Rationale:
Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as
std::__1::vector<int, std::__1::allocator<....
rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code
Proposed solution:
Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name
Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point
LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem
Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice
The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one
It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type
Caveats:
- for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet.
- while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters

Also moved it into the lldb_private namespace.
The llgs branch is making use of this interface and its use is not
strictly limited to POSIX.

Use a map rather than a vector to store the objects managed by the shared
cluster since mostly want this for random lookup, so the map is much faster.

- Tested with Eclipse, likely to work with other GDB/MI compatible GUIs.
- Some but not all MI commands have been implemented. See MIReadme.txt for more info.
- Written from scratch, no GPL code, based on LLDB Public API.
- Built for Linux, Windows and OSX. Tested on Linux and Windows.

This is meant to address case 3 that I recently broke with an earlier
change to rectify usage of the $qC message for thread ids, specifically:
3. TOT lldb <=> gdbserver (without $qProcessInfo support and not Apple/iOS).

the SystemRuntime to check if a thread will have any problems
performing an inferior function call so the driver can skip
making that function call on that thread. Often the function
call can be executed on another thread instead.

The clean line is failing under Ubuntu 12.04/gcc. It cleans fine
without it on MacOSX. It doesn't clean right on Linux but at least
now it doesn't fail the test.

Python defines _XOPEN_SOURCE and _POSIX_C_SOURCE unconditionally. On Linux,
this is problematic as glibc's features.h defines these values if _GNU_SOURCE is
defined to the value that is currently implemented. Python defines it to the
versions that it requires, which may be different. Undefine the macros on Linux
(technically, this should be safe to do globally) before including the python
headers.

another way to indicate that this register is a generic
Return Address register (in addition to "ra") - this is
used primarily by OperatingSystem plugins.
Correctly annotate the UnwindPlan created by EmulateInstructionARM64
to indicate that it was not sourced from a compiler and it
is valid at every instruction.

$qC from debugserver now returns the current thread's thread-id (and, like $?, will set a current thread if one is not already selected). Previously it was returning the current process id.
lldb will now query $qProcessInfo to retrieve the process id. The process id is now cached lazily and reset like other cached values. Retrieval of the process id will fall back to the old $qC method for vendor==Apple and os==iOS if the qProcessInfo retrieval fails.
Added a gdb remote protocol-level test to verify that $qProcessInfo reports a valid process id after launching a process, while the process is in the initial stopped state. Verifies the given process id is a currently valid process on host OSes for which we know how to check (MacOSX, Linux, {Free/Net}BSD). Ignores the live process check for OSes where we don't know how to do this. (I saw no portable way to do this in stock Python without pulling in other libs).

The FreeBSD package building cluster installs e.g. 'python2.7', but no
plain 'python' to avoid version-related issues.
CMake's FindPythonInterp locates an interpreter with such a name and
provides it in the PYTHON_EXECUTABLE variable. Use that if it's set,
falling back to the original '/usr/bin/env python' otherwise.
This is a missing part of LLDB commit r207122.

Added a test validating that $qC after an inferior launch via $A
returns a thread id that an immediately followig $? reports for the
active thread. This is currently skipped on debugserver (the thread
ids don't match) and isn't yet implemented in TOT for llgs.

data if it is available.
Change ProcessGDBRemote's maximum read/write packet size from a
fixed 512 byte value to asking the remote gdb stub what its maximum
is, using up to 128kbyte sizes if that's allowed, and falling back
to 512 if the remote gdb stub doesn't advertise a max packet size.
Add a new "process plugin packet xfer-size" command that can be used
to override the maximum packet size (although not exceeding any packet
size maximum published by the remote gdb stub).

Pushed gdbremote protocol sequence expectations into a separate
class and defer matching of llgs/debugserver output to the
sequence entry. Pre-step to adding regex matching and
grouped content collecting.
No longer require anything before the read/send packet
portion of slurped-up log lines used for setting up
gdb remote test sequences. Several packet logging options
produce a wide range of content before the read/send packet.
Added helpers to TestLldbGdbServer to clean up test setup
and test expectations matching.
