Get debugserver to call task_set_state to prime the control registers so that watchpoints
take for threads created while the program is running. Remove the testcase skips from TestConcurrentEvents.py,
since they all pass now, and fix TestWatchpointMultipleThreads.py - which should have caught this problem -
so it doesn't artificially break on new thread creation before the watchpoint triggers.

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.

Designate MachThreadList as a transaction coordinator when doing Enable/DisableHardwareWatchpoint on the list of threads.
In case the operation (iterating on the threads and doing enable/disable) fails in the middle, we rollback the already
enabled/disabled threads to their checkpointed states. When all the threads succeed in enable/disable, we ask each thread
to finsih the transaction and commit the change of the debug state.

Modify the delegation chain from MachThreadList -> MachThread -> DNBArchProtocol so that when
the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.
Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.
Modify TestWatchpointMultipleThreads.py to test this functionality.

Convert lldb::ModuleSP to use an instrusive ref counted pointer.
We had some cases where getting the shared pointer for a module from
the global module list was causing a performance issue when debugging
with DWARF in .o files. Now that the module uses intrusive ref counts,
we can easily convert any pointer to a shared pointer.

Add logic to the DNBArchImplX86_64/DNBArchImplI386::NotifyException() callback method
in order to distinguish the real single step exception from a watchpoint exception
which uses the same exc_type of EXC_BREAKPOINT and exc_code of EXC_I386_SGL.
This is done by checking the debug status register to find out whether the watchpoint
data break event has fired, and, if yes, stuff the data break address into the exception's
exc_sub_code field on the debugserver side for lldb to consume on the other end.

Then
lldb /path/to/executable

Added new OptionGroup classes for UInt64, UUID, File and Boolean values.
Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules".
Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]
So you can load individual sections without running a target:
(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000
Or you can rigidly slide an entire shared library:
(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000
This should improve bare board debugging when symbol files need to be slid around manually.

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.

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.
