Found a race condition when killing an application where the state could be set to exited by the waitpid_thread() _before_ we call task resume (via MachProcess::PrivateResume()) in MachProcess::Kill().

Huge performance improvements when one breakpoint contains many locations.
325,000 breakpoints for running "breakpoint set --func-regex ." on lldb itself (after hitting a breakpoint at main so that LLDB.framework is loaded) used to take up to an hour to set, now we are down under a minute. With warm file caches, we are at 40 seconds, and that is with setting 325,000 breakpoint through the GDB remote API. Linux and the native debuggers might be faster. I haven't timed what how much is debug info parsing and how much is the protocol traffic to/from GDB remote.
That there were many performance issues. Most of them were due to storing breakpoints in the wrong data structures, or using the wrong iterators to traverse the lists, traversing the lists in inefficient ways, and not optimizing certain function name lookups/symbol merges correctly.
Debugging after that is also now very efficient. There were issues with replacing the breakpoint opcodes in memory that was read, and those routines were also fixed.

Change debugserver from using the mach port number (in debugserver's
own port namepsace) as the thread identifier to using the system-wide
globally unique thread id as the thread identifier number.
MachThread.cpp keeps both the unique id and the mach port number
for each thread. All layers outside MachThread class use the unique
id with three exceptions: (1) Mach exceptions come in with the port
number (thread_port) which needs to be translated, (2) any calls to
low-level thread_get_state/thread_set_state/thread_suspend etc need
to use the mach port number, (3) MachThreadList::UpdateThreadList
which creates the MachThread objects gets the unique id and passes
it to the MachThread ctor as an argument.
In general, any time nub_thread_t is used, it is now referring to a
unique thread id. Any time a thread_t is used, it is now referring
to a mach port number. There was some interchangability of these
types previously. nub_thread_t has also been changed to a 64-bit
type which necessitated some printf specification string changes.
I haven't been able to test these changes extensively yet but want
to checkpoint the work. The scenarios I've been testing are all
working correctly so while there may be some corner cases I haven't
hit yet, I think it is substantially correct.

Add unconditional logging messages to every place in debugserver
where we send a SIGKILL signal or do a ptrace PT_KILL call to
terminate the inferior process. When the debuggee is silently
killed off, the console logging from debugserver can disambiguate
whether debugserver killed off the process because it failed to
completely set it up, becuase it was told to (via the "k" packet),
or if some external daemon killed it.

Added optional calls to lldb_private::Process for getting memory region info
from a process and hooked it up to the new packet that was recently added
to our GDB remote executable named debugserver. Now Process has the following
new calls:
virtual Error
Process::GetMemoryRegionInfo (lldb::addr_t load_addr, MemoryRegionInfo &range_info);
virtual uint32_t
GetLoadAddressPermissions (lldb::addr_t load_addr);
Only the first one needs to be implemented by subclasses that can add this
support.
Cleaned up the way the new packet was implemented in debugserver to be more
useful as an API inside debugserver. Also found an error where finding a region
for an address actually will pick up the next region that follows the address
in the query so we also need ot make sure that the address we requested the
region for falls into the region that gets returned.

Remove the QAddressIsExecutable packet I added last night.
Add a more general purpose qMemoryRegionInfo packet which can
describe various attributes about a memory region. Currently it
will return the start address, size, and permissions (read, write,
executable) for the memory region. It may be possible to add
additional attributes in the future such as whether the region is
designated as stack memory or jitted code a la vmmap.
I still haven't implemented the lldb side of the code to use this
packet yet so there may be unexpected behavior - but the basic implementation looks
about right. I'll hook it up to lldb soon and fix any problems that crop up.

Add "QAddressIsExecutable" packet to debugserver. Used to test
whether a given address is in an executable region of memory or
not. I haven't written the lldb side that will use this packet it
hasn't been tested yet but it's a simple enough bit of code.
I want to have this feature available for the unwinder code. When
we're stopped at an address with no valid symbol context, there are
a number of questions I'd like to ask --
is the current pc value in an executable region (e.g. did they
jump to unallocated/unexecutable memory? we know how to unwind
from here if so.)
Is the stack pointer or the frame pointer the correct register
to use to find the caller's saved pc value?
Once we're past the first frame we can trust things like eh_frame
and ABI unwind schemes but the first frame is challenging and having
a way to check potential addresses to see if they're executable or
not would help narrow down the possibilities a lot.

Fixed the Xcode project building of LLVM to be a bit more user friendly:
- If you download and build the sources in the Xcode project, x86_64 builds
by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
Xcode project will download the right LLVM sources and build them from
scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
directory, we will use the sources you have placed in the LLDB directory.
Python can now be disabled for platforms that don't support it.
Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

Python does some bad things to the signal masks in the current process and
then we spawn child processes (debugserver, etc) and those bad settings get
inherited. We stop this from happening by correctly mucking with the posix
spawn attributes.

Fixed CommandReturnObject::SetImmediateErrorFile() to set the correct stream.
Modifed lldb_private::Process to be able to handle connecting to a remote
target that isn't running a process. This leaves lldb_private::Process in the
eStateConnected state from which we can then do an attach or launch.
Modified ProcessGDBRemote to be able to set stdin, stdout, stderr, working
dir, disable ASLR and a few other settings down by using new GDB remote
packets. This allows us to keep all of our current launch flags and settings
intact and still be able to communicate them over to the remote GDB server.
Previously these were being sent as arguments to the debugserver binary that
we were spawning. Also modified ProcessGDBRemote to handle losing connection
to the remote GDB server and always exit immediately. We do this by watching
the lldb_private::Communication event bit for the read thread exiting in the
ProcessGDBRemote async thread.
Added support for many of the new 'Q' packets for setting stdin, stdout,
stderr, working dir and disable ASLR to the GDBRemoteCommunication class for
easy accesss.
Modified debugserver for all of the new 'Q' packets and also made it so that
debugserver always exists if it loses connection with the remote debugger.

Added a new variant of SBTarget::Launch() that deprectates the old one that
takes separate file handles for stdin, stdout, and stder and also allows for
the working directory to be specified.
Added support to "process launch" to a new option: --working-dir=PATH. We
can now set the working directory. If this is not set, it defaults to that
of the process that has LLDB loaded. Added the working directory to the
host LaunchInNewTerminal function to allows the current working directory
to be set in processes that are spawned in their own terminal. Also hooked this
up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its
API changed, but nothing is making use of it yet. Modfied "debugserver" and
"darwin-debug" to also handle the current working directory options and modified
the code in LLDB that spawns these tools to pass the info along.
Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout
and stderr.
After clearing the default values for the stdin/out/err file handles for
process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable
which is now fixed. Also fixed the setting of boolean values to be able to
be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no",
"off", or "0" for false.
Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not
already opened. Previous to this fix debugserver would only correctly open and dupe
file handles for the slave side of a pseudo terminal. It now correctly handles
getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to
files. Also made sure the file handles were correctly opened with the NOCTTY flag
for terminals.

Fixed an issue in "SBError SBProcess::Destroy ()" where it wasn't properly
checking the validity of the shared pointer prior to using it.
Fixed the GDB remote plug-in to once again watch for a reply from the "k"
packet, and fixed the logic to make sure the thread requesting the kill
and the async thread play nice (and very quickly) by synchronizing the
packet sending and reply. I also tweaked some of the shut down packet
("k" kill, "D" detach, and the halt packet) to make sure they do the right
thing.
Fixed "StateType Process::WaitForProcessStopPrivate (...)" to correctly pass
the timeout along to WaitForStateChangedEventsPrivate() and made the function
behave correctly with respect to timing out.
Added separate STDIN, STDOUT, and STDERR support to debugserver. Also added
the start of being able to set the working directory for the inferior process.

Thread safety changes in debugserver and also in the process GDB remote plugin.
I added support for asking if the GDB remote server supports thread suffixes
for packets that should be thread specific (register read/write packets) because
the way the GDB remote protocol does it right now is to have a notion of a
current thread for register and memory reads/writes (set via the "$Hg%x" packet)
and a current thread for running ("$Hc%x"). Now we ask the remote GDB server
if it supports adding the thread ID to the register packets and we enable
that feature in LLDB if supported. This stops us from having to send a bunch
of packets that update the current thread ID to some value which is prone to
error, or extra packets.

Add '-no-stdio' option to 'process launch' command, which causes the
inferior to be launched without setting up terminal stdin/stdout for it
(leaving the lldb command line accessible while the program is executing).
Also add a user settings variable, 'target.process.disable-stdio' to allow
the user to set this globally rather than having to use the command option
each time the process is launched.

Fixed Process::Halt() as it was broken for "process halt" after recent changes
to the DoHalt down in ProcessGDBRemote. I also moved the functionality that
was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has
to implement a tricky halt/resume on the internal state thread. The
functionality is the same as it was before with two changes:
- when we eat the event we now just reuse the event we consume when the private
state thread is paused and set the interrupted bool on the event if needed
- we also properly update the Process::m_public_state with the state of the
event we consume.
Prior to this, if you issued a "process halt" it would eat the event, not
update the process state, and then produce a new event with the interrupted
bit set and send it. Anyone listening to the event would get the stopped event
with a process that whose state was set to "running".
Fixed debugserver to not have to be spawned with the architecture of the
inferior process. This worked fine for launching processes, but when attaching
to processes by name or pid without a file in lldb, it would fail.
Now debugserver can support multiple architectures for a native debug session
on the current host. This currently means i386 and x86_64 are supported in
the same binary and a x86_64 debugserver can attach to a i386 executable.
This change involved a lot of changes to make sure we dynamically detect the
correct registers for the inferior process.

If debugserver is running on the local machine, pass it a
pseudoterminal to pass to the inferior for the inferior's I/O
(to allow direct writing, rather than passing all the I/O around
via packets).

Fix problem where "process detach" was not working properly. The
ptrace thread update that was replying to the SIGSTOP was also causing the
process to not really be sigstop'd any more so then the call to ptrace
detach was failing, and when debugserver exited the attached process
was being killed. Now the ptrace thread update does not disturb the sigstop
state of the thread, so the detach works properly.

Got the ARM version of debugserver up to date.
Renamed the "dispatchqaddr" setting that was coming back for stop reply packets
to be named "qaddr" so that gdb doesn't thing it is a register number. gdb
was checking the first character and assuming "di" was a hex register number
because 'd' is a hex digit. It has been shortened so gdb can safely ignore it.
