Add an explicit check for a darwin kernel KDP_VERSIONSTRING when
starting a kdp communication session, instead of assuming darwin
kernel for any "non-EFI" kdp session.

Identify a kdp session that is connecting to an EFI monitor,
use a DynamicLoaderStatic dynamic loader for the session
instead of a kernel or user dynamic loader.

Added commands to the KDP plug-in that allow sending raw commands through the KDP protocol. You specify a command byte and a payload as ASCII hex bytes, and the packet is created with a valid header/sequenceID/length and sent. The command responds with a raw ASCII hex string that contains all bytes in the reply including the header.
An example of sending a read register packet for the GPR on x86_64:
(lldb) process plugin packet send --command 0x07 --payload 0100000004000000

Add support for debugging KASLR kernels via kdp (the kernel being
loaded at a random offset).
To get the kernel's UUID and load address I need to send a kdp
packet so I had to implement the kernel relocation (and attempt to
find the kernel if none was provided to lldb already) in ProcessKDP
-- but this code really properly belongs in DynamicLoaderDarwinKernel.
I also had to add an optional Stream to ConnectRemote so
ProcessKDP::DoConnectRemote can print feedback about the remote kernel's
UUID, load address, and notify the user if we auto-loaded the kernel via
the UUID.

No functionality changes, mostly cleanup.
Cleaned up the Mutex::Locker and the ReadWriteLock classes a bit.
Also cleaned up the GDBRemoteCommunication class to not have so many packet functions. Used the "NoLock" versions of send/receive packet functions when possible for a bit of performance.

Trying to solve our disappearing thread issues by making thread list updates safer.
The current ProcessGDBRemote function that updates the threads could end up with an empty list if any other thread had the sequence mutex. We now don't clear the thread list when we can't access it, and we also have changed how lldb_private::Process handles the return code from the:
virtual bool
Process::UpdateThreadList (lldb_private::ThreadList &old_thread_list,
lldb_private::ThreadList &new_thread_list) = 0;
A bool is now returned to indicate if the list was actually updated or not and the lldb_private::Process class will only update the stop ID of the validity of the thread list if "true" is returned.
The ProcessGDBRemote also got an extra assertion that will hopefully assert when running debug builds so we can find the source of this issue.

Third round of code cleanups:
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
- applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
- fixed an issue where command type summary add for type "struct Foo" would not match any types.
currently, "struct" will be stripped off and type "Foo" will be matched.
similar behavior occurs for class, enum and union specifiers.

Modified the LocateMacOSXFilesUsingDebugSymbols(...) function to locate
an executable file if it is right next to a dSYM file that is found using
DebugSymbols. The code also looks into a bundle if the dSYM file is right
next to a bundle.
Modified the MacOSX kernel dynamic loader plug-in to correctly set the load
address for kext sections. This is a tad tricky because of how LLDB chooses
to treat mach-o segments with no name. Also modified the loader to properly
handle the older version 1 kext summary info.
Fixed a crasher in the Mach-o object file parser when it is trying to set
the section size correctly for dSYM sections.
Added packet dumpers to the CommunicationKDP class. We now also properly
detect address byte sizes based on the cpu type and subtype that is provided.
Added a read memory and read register support to CommunicationKDP. Added a
ThreadKDP class that now uses subclasses of the RegisterContextDarwin_XXX for
arm, i386 and x86_64.
Fixed some register numbering issues in the RegisterContextDarwin_arm class
and added ARM GDB numbers to the ARM_GCC_Registers.h file.
Change the RegisterContextMach_XXX classes over to subclassing their
RegisterContextDarwin_XXX counterparts so we can share the mach register
contexts between the user and kernel plug-ins.

Added a boolean to the pure virtual lldb_private::Process::CanDebug(...)
method so process plug-ins that are requested by name can answer yes when
asked if they can debug a target that might not have any file in the target.
Modified the ConnectionFileDescriptor to have both a read and a write file
descriptor. This allows us to support UDP, and eventually will allow us to
support pipes. The ConnectionFileDescriptor class also has a file descriptor
type for each of the read and write file decriptors so we can use the correct
read/recv/recvfrom call when reading, or write/send/sendto for writing.
Finished up an initial implementation of UDP where you can use the "udp://"
URL to specify a host and port to connect to:
(lldb) process connect --plugin kdp-remote udp://host:41139
This will cause a ConnectionFileDescriptor to be created that can send UDP
packets to "host:41139", and it will also bind to a localhost port that can
be given out to receive the connectionless UDP reply.
Added the ability to get to the IPv4/IPv6 socket port number from a
ConnectionFileDescriptor instance if either file descriptor is a socket.
The ProcessKDP can now successfully connect to a remote kernel and detach
using the above "processs connect" command!!! So far we have the following
packets working:
KDP_CONNECT
KDP_DISCONNECT
KDP_HOSTINFO
KDP_VERSION
KDP_REATTACH
Now that the packets are working, adding new packets will go very quickly.

Completed more work on the KDP darwin kernel debugging Process plug-in.
Implemented connect, disconnect, reattach, version, and hostinfo.
Modified the ConnectionFileDescriptor class to be able to handle UDP.
Added a new Stream subclass called StreamBuffer that is backed by a
llvm::SmallVector for better efficiency.
Modified the DataExtractor class to have a static function that can
dump hex bytes into a stream. This is currently being used to dump incoming
binary packet data in the KDP plug-in.

Added the ability to connect using "tcp://<host>:<port>" which is the
same as the old "connect://<host>:<port>". Also added the ability to
connect using "udp://<host>:<port>" which will open a connected
datagram socket. I need to find a way to specify a non connected
datagram socket as well.
We might need to start setting some settings in the URL itself,
maybe something like:
udp://<host>:<port>?connected=yes
udp://<host>:<port>?connected=no
I am open to suggestions for URL settings.
Also did more work on the KDP darwin kernel plug-in.
