Modified the lldb_private::Thread to work much better with the OperatingSystem plug-ins. Operating system plug-ins can now return have a "core" key/value pair in each thread dictionary for the OperatingSystemPython plug-ins which allows the core threads to be contained with memory threads. It also allows these memory threads to be stepped, resumed, and controlled just as if they were the actual backing threads themselves.
A few things are introduced:
- lldb_private::Thread now has a GetProtocolID() method which returns the thread protocol ID for a given thread. The protocol ID (Thread::GetProtocolID()) is usually the same as the thread id (Thread::GetID()), but it can differ when a memory thread has its own id, but is backed by an actual API thread.
- Cleaned up the Thread::WillResume() code to do the mandatory parts in Thread::ShouldResume(), and let the thread subclasses override the Thread::WillResume() which is now just a notification.
- Cleaned up ClearStackFrames() implementations so that fewer thread subclasses needed to override them
- Changed the POSIXThread class a bit since it overrode Thread::WillResume(). It is doing the wrong thing by calling "Thread::SetResumeState()" on its own, this shouldn't be done by thread subclasses, but the current code might rely on it so I left it in with a TODO comment with an explanation.

- Required for platform-independant handling of general purpose registers (i.e. for core dumps).
Thanks to Samuel Jacob for this patch.

- Adds unique enums for ymm registers to the ABI and the POSIX register context.
- Reworks the register context data structures to support a union of FXSAVE and XSAVE
--- Allows the same code base to deal with the FPU independent of the availability of AVX.
- Determine if AVX is supported by attempting to read XSAVE using ptrace.
--- Support an extended register set for avx registers if available.
- Provide a mechanism to assemble/parse register halves into a single ymm buffer for use with RegisterValue.
--- Reworked Read/WriteRegister routines to read/write/parse ymm registers.
Adds tests for ymm register write with read-back, and expressions involving ymm registers.
- Tests vary depending on the availability of an avx register set.
Thanks to Daniel and Matt for their reviews.

- process in 'unloaded' state was (incorrectly) considered to be alive by POSIX plugin
- above caused a regression in TestProcessLaunch cases

- Includes a stub for AVX support in the x86-64 register context and a failing test for register sets that are unavailable.
Thanks to Greg Clayton for his review feedback.

- All Linux logging channels now use a single global instance of lldb_private::Log, to handle the case of logging during process tear down.
- Also removed a single use of LogSP in FreeBSD and fixed a typo in a comment while reading through ProcessKDPLog.

- generate-vers.pl has to be called by cmake to generate the version number
- parallel builds not yet supported; dependency on clang must be explicitly specified
Tested on Linux.
- Building on Mac will require code-signing logic to be implemented.
- Building on Windows will require OS-detection logic and some selective directory inclusion
Thanks to Carlo Kok (who originally prepared these CMakefiles for Windows) and Ben Langmuir
who ported them to Linux!

The attached patch fixes a problem with performing an attach from the SBTarget API on Linux (and other systems that use ProcessPOSIX).
When Process::Attach was called from SBTarget, it resulted in a call to a form of the DoAttachWithID function that wasn't implemented in ProcessPOSIX, and so it fell back to the default implementation (which just returns an error). It didn't seem necessary to use the attach_info parameter for this case, so I just implemented it as a call to the simpler version of the function.
In debugging this problem, I also found that SBTarget wasn't checking the return value from the Attach call, causing it to hang when the attach fails.

Hello everyone,
please find the attached patch for TOT and lldb-platform-work branch, which provides the following changes:
- fixed a crash in the ProcessPOSIX constructor when an executable module object is not yet created.
- added support for the multi instanciated FreeBSD platform objects (the local host and remote as example).
- enabled the remote gdb plugin on FreeBSD.

Initial step -- infrastructure change -- to fix the bug. Change the RegisterInfo data structure
to contain two additional fields (uint32_t *value_rges and uint32_t *invalidate_regs) to facilitate
architectures which have register mapping.
Update all existing RegsiterInfo arrays to have two extra NULL's (the additional fields) in each row,
GDBRemoteRegisterContext.cpp is modified to add d0-d15 and q0-q15 register info entries which take
advantage of the value_regs field to specify the containment relationship:
d0 -> (s0, s1)
...
d15 -> (s30, s31)
q0 -> (d0, d1)
...
q15 -> (d30, d31)

This patch combines common code from Linux and FreeBSD into
a new POSIX platform. It also contains fixes for 64bit FreeBSD.
The patch is based on changes by Mark Peek <mp@FreeBSD.org> and
"K. Macy" <kmacy@freebsd.org> in their github repo located at
https://github.com/fbsd/lldb.
