Added a unit test to test debugserver and llgs compliance on --named-pipe support.
Modified llgs to implement --named-pipe support. (Note: need to revisit with
new generic pipe support).

The fix adds a std::weak_ptr<Module> into the TypeImpl and fills in the weak pointer when possible. It also checks to make sure the module is still alive prior to using it which should make our API safer to use.

If we have any section headers in the collection, we already parsed them.
Therefore, don't reparse the section headers when the section_headers collection
is not empty.

This patch fixes a number of issues with embedded Python on
Windows. In particular:
1) The script that builds the python modules was normalizing the
case of python filenames during copies. The module name is
the filename, and is case-sensitive, so this was breaking code.
2) Changes the build to not attempt to link against python27.lib
(e.g. the release library) when linking against msvcrt debug
library. Doing a debug build of LLDB with embedded python
support now requires you to provide your own self-compiled
debug version of python.
3) Don't import termios when initializing the interpreter. This
is part of a larger effort to remove the dependency on termios
since it is not available on Windows. This particular instance
was unnecessary and unused.

Fixes include:
- Don't say that "<arch>-apple-ios" is compatible with "<arch>-apple-macosx"
- Fixed DynamicLoaderMacOSXDYLD so specify an architecture that was converted solely from a cputype and subtype, just specify the file + UUID.
- Fixed PlatformiOSSimulator::GetSupportedArchitectureAtIndex() so it returns the correct archs
- Fixed SymbolFileDWARFDebugMap to load .o files correctly by just specifying the architecture without the vendor and OS now that "<arch>-apple-ios" is not compatible with "<arch>-apple-macosx" so we can load .o files correctly for DWARF with debug map
- Fixed the coded in TargetList::CreateTarget() so it does the right thing with an underspecified triple where just the arch is specified.

The following intermittently-failing tests have been flipped from
skip to XFAIL on some combo of Linux and MacOSX:
TestCallStopAndContinue.py (Linux, MacOSX)
TestCallWithTimeout.py (Linux)
TestConvenienceVariables.py (Linux)
TestStopHookMultipleThreads.py (Linux)
The following new tests have been marked XFAIL but are just
intermittently failing:
TestMultipleDebug.py (definitely intermittent on MacOSX, not sure I've seen
it pass yet on Linux)

Being in lldb\source, ${CMAKE_CURRENT_BINARY_DIR} would resolve to
the build\tools\lldb\source directory. For correct operation, and
parity with the shell script, it needs to resolve to the
build\tools\lldb\scripts directory.

These fix the broken debian lldb build, which is using g++ 4.7.2.
TypeFormat changes:
1. stopped using the C++11 "dtor = default;" construct.
The generated default destructor in the two derived classes wanted
them to have a different throws() semantic that was causing 4.7 to
fail to generate it. I switched these to empty destructors defined
in the .cpp file.
2. Switched the m_types map from an ordered map to an unordered_map.
g++ 4.7's c++ library supports the C++11 emplace() used by TypeFormat
but the same c++ library's map impl does not. Since TypeFormat didn't
look like it depended on ordering in the map, I just switched it to
a std::unordered_map.
NativeProcessLinux - g++ 4.7 chokes on lexing the "<::" in
static_cast<::pid_t>(wpid). g++ 4.8+ and clang are fine with it.
I just put a space in between the "<" and the "::" and that cleared
it up.

debug sessions simultaneously to expose race conditoin/locking
issues.
This directory has an inferior program, testprog.cpp that has a
couple of functions we can put breakpoints on.
It has a driver program, multi-process-driver.cpp, which links
against the LLDB solib and uses the SB APIs. It creates 50 pthreads,
creates a debugger on all of them, launches a debug session of the
inferior testprog, hits a couple breakpoints, walks the stack,
continues, etc., and then kills the inferior and ends the debug
session.
A pass is if all fifty debug sessions complete successfully
in the alloted time (~60 seconds).
We may need to tweak this one to work correctly on different
platforms/targets but I wanted to get it checked in to start.

Fixed up gdb-remote port-grabbing code to use a random port in a wide range,
and to allow that to fail more gracefully. This appears to have solved some
gdb-remote intermittent failing behavior.

All tests matching '-p TestObjCMethods' now are marked correctly for MacOSX, and some
error classes have been removed in cleanup code looking for files that
might not exist due to previous failure.

The current strategy for host allocation is to choose a random
address and attempt to allocate there, eventually failing if the
allocation cannot be satisfied.
The C standard only guarantees that RAND_MAX >= 32767, so for
platforms that use a very small RAND_MAX allocations will fail
with very high probability. On such platforms (Windows is one),
you can reproduce this trivially by running lldb, typing "expr (3)"
and then hitting enter you see a failure. Failures generally
happen with a frequency of about 1 failure every 5 evaluations.
There is no good reason that allocations need to look like "real"
pointers, so this patch changes the allocation scheme to simply
jump straight to the end and grab a free chunk of memory.

The getopt library has a structure called option (lowercase). We
have a structure called Option (uppercase). previously the two
structures had exactly the same definitions, and we were doing a
C-style cast of an Option* to an option*. C-style casts don't
bother to warn you when you cast to unrelated types, but in the
original OptionValidator patch I modified the definition of Option.
This patch fixes the errors by building an array of option
structures and filling it out the correct way before passing it to
the getopt library.
This also fixes one other source of test failures: an uninitialized
read that occurs due to not initializing a field of the
OptionDefinition.

On MacOSX, we need to adjust the way we clean up the crashlog dylib in deleteCrashInfoDylib().
Right now it is only geared to run one test at a time. For now I'm just skipping the delete.
I'll work with Apple on a fix that handles this. It seems to only cause one dylib total to
hang around that might otherwise have been deleted. Fixes MacOSX multiple tests running
at the same time. (I didn't hit this on Yosemite, might be an issue that only shows up
on Mavericks?)

This reverses out the options validators changes. We'll get these
back in once the changes to the output can be resolved.

This change modifies the way the multi-threaded test runner works.
It uses the Python multiprocessing library rather than the threading
library. Investigation showed that all MacOSX threads were waiting on
the global python lock when using the threading approach. Not sure
why that differed from the Linux/FreeBSD implementations.
The new approach uses the multiprocessing library's Pool class. It's
mildly cleaner than the other version, runs multithreaded on MacOSX,
and seems to have caused no performance regression on Linux. The
worker thread logic is simpler with the Pool managing the worker
processes.
This also includes a minor change to the test runner's python
lldb dir logic using the -P option. It now looks at the last line
of output rather than the first line. This covers part of the issue
of extra options validation logic getting spit out. The test runner
will now pick up the right python library directory. It does not
fix all the issues, though, as a ton of tests (50+ on Linux) are
failing due to unexpected output when running lldb.
