Summary:
    This merge brings in the improved 'platform' command that knows how to
    interface with remote machines; that is, query OS/kernel information, push
    and pull files, run shell commands, etc... and implementation for the new
    communication packets that back that interface, at least on Darwin based
    operating systems via the POSIXPlatform class. Linux support is coming soon.

    Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
    X Mountain Lion.

    Additional improvements (not in the source SVN branch 'lldb-platform-work'):
    - cmake build scripts for lldb-platform
    - cleanup test suite
    - documentation stub for qPlatform_RunCommand
    - use log class instead of printf() directly
    - reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
    - add new logging category 'platform'

- Addresses review comments from Stefanus!

- add new "--libcxx" parameter to dotest.py to specify path to custom libc++

The tests use a plugin based on the name from sys.platform.
Unfortunately that string includes the major version number in
Python 2.7, so the tests would look for builder_freebsd9.py,
builder_freebsd10.py, etc.

The issue doesn't affect Linux as Python returns 'linux2' also
on Linux 3.x -- see http://bugs.python.org/issue12326 for details.

It seems later versions of Python will drop the major version
number, so adopt this convention now for FreeBSD.

- Test verifies LLDB's handling of inferiors with threads that: hit breakpoints,
  modfiy variables that have watchpoints set, generate user signals, and crash.
- Add a few "stress tests" (with ~100 threads) -- run these with "-l" dotest.py
  flag.
- Fix stop_reason_to_str helper in lldbutil to handle eStopReasonThreadExited.
- Add sort_stopped_threads helper to lldbutil to separate thread lists based
  on stop reason.

Logged llvm.org/pr16566 and llvm.org/pr16567 for bugs exposed.

There's still significant work to do in the FreeBSD port, so no point
in a pr for these yet.

This is a rewrite of the command history facility of LLDB

It takes the history management out of the CommandInterpreter into its own CommandHistory class
It reimplements the command history command to allow more combinations of options to work correctly (e.g. com hist -c 1 -s 5)
It adds a new --wipe (-w) option to command history to allow clearing the history on demand
It extends the lldbtest runCmd: and expect: methods to allow adding commands to history if need be
It adds a test case for the reimplemented facility

- For instance, allows 'gcc' to match x86-64-linux-gnu-gcc as required on some Debian builds.
- Also adds doc-strings and a more consistent naming convention for related helpers.

llvm-svn: 183415

- one test case is due to llvm.org/pr16229
- other test case uses a Linux workaround for above by using os.fork() instead of subprocess module

Patch by Andy Kaylor!

llvm-svn: 183340

Adding support for stopping all threads of multithreaded inferiors on Linux.  Also adding multithreaded test cases.

llvm-svn: 182809

- Note that this is not correct, as the failure is associated with build options of libc.so, however it's failing on a Debian buildbot that uses gcc 4.6.2 (and the real goal is a complete backtrace even with -fomit-frame-pointer).

- Adds helpers to lldbtest.py to check the expectedCompiler and expectedVersion, with an eventual goal of reducing the number of test decorators.
--- Currently allows a comparison operator and a compiler version to be specified.
--- Can be extended to support ranges of compiler versions.

llvm-svn: 182155

- On Linux, the partial back-trace after an assert can cause the basic test to fail as discussed on lldb-dev.
- Uses SBFrame to walk up the stack to the assert site and tests expression evaluation of locals, globals and arguments.

Thanks to Daniel for review and testing on OS/X.

llvm-svn: 182115

- s/skipOnLinux/skipIfLinux/ to match style of every other decorator
- linkify bugizilla/PR numbers in comments

No intended change in functionality.

llvm-svn: 181913

llvm-svn: 181857

- older versions of clang are unable to include <chrono> from libstdc++
- skipping tests until buildbots are updated

llvm-svn: 181829

llvm-svn: 181341

llvm-svn: 181239

- moved build logic from Makefile and TestPublicAPIHeaders.py into lldbtest to allow reuse
- added decorator @skipIfi386

llvm-svn: 180955

-adds icc to the lit of compilers to run the tests
-adds icc test decorators
-skip TestAnonymous.py for icc

Fix the getCompilerVersion() function to do the right thing with clang 5.0 which now says "LLVM version" instead of "clang version".

llvm-svn: 176282

- pull up logic to get compiler version from TestUniqueTypes.py into lldbtest.py
- work around an GCC 4.6.3 issue

llvm-svn: 176190

Fixing issues in previous checkin - still figuring out how to make expectedFailureClang take the bugnumber

llvm-svn: 175945

The decorators @expectedFailure (plain and special-case like i386, clang, ...) are modified to optionally take a bugnumber argument
If such an argument is specified, the failure report (or unexpected success report) will include the information passed in as part of the message
This is mostly useful for associating failures to issue IDs in issue management systems (e.g. the LLVM bugzilla)

llvm-svn: 175942

- replace "catch-all" except clause with one that specifically catches what pexpect throws
- handle case where child is already terminated (or is terminating) by the time tear-down is run

llvm-svn: 175844

- rework the way SBDebugger.SetAsync() is used to avoid side effects (reset original value at TearDownHook)
- refactor expectedFailureClang (and add expectedFailureGcc decorator)
- mark TestChangeValueAPI.py as expectedFailureGcc due to PR-15039

llvm-svn: 175523

- fixed cleanup of Popen objects by pushing spawn logic into test Base and out of test cases
- connect subprocess stdin to PIPE (rather than the parent's STDIN) to fix silent terminal issue

Tested on Linux and Mac OS X

llvm-svn: 175301

- set auto-confirm to false when running TestExprs (avoid hang when using API)
- set prompt-on-quit to false in test helper (avoid timeout when using lldb CLI)

llvm-svn: 173485

- Add new decorator "@skipIfGcc" to lldbtest.py

llvm-svn: 173394

The skipOnLinux decorator wasn't calling the test method correctly (no need to pass in the "self") resulting
in errors on MacOS X for the tests so decorated.

llvm-svn: 168662

- use lldb 'settings' command to help testcase find shared library
- pull up dyldPath variable from TestLoadUnload.py to fixture base class (applicable in multiple cases)

llvm-svn: 168612

- add decorators @expectedFailLinux and @skipOnLinux
- skip/mark xfail cases due to open bugzillas # 14323, 14416, 14423, 14424, 14425, 14426
