* commit '012090e57b697133ad6f7d989e103d71302749f8':
  Only copy mcontext data from sigcontext.

e484607622 Only copy mcontext data from sigcontext. 
The ucontext_t data structure could be bigger than the kernel data
structure. Since the unwinder only cares about the mcontext data, only
copy that out of the structure. The mcontext data is the same size in
the kernel and in the ucontext_t structure.

a3a8f6d2ab Remove libstdc++ dependency from host libbacktrace 
The libc++ version of libbacktrace on the host was still linking against
libstdc++, and this was causing problems in art.

ac2fe7eb81 Add missing headers 
These headers are needed for pid_t and free when using libc++ headers (POSIX
does not require that the symbols be exposed with the previous includes).

a2efd3ac7a Rewrite unwind thread handling. 
This new version doesn't require any specialized thread
implementation, it uses the Current implementation to do its job.
In addition, it runs much faster when multiple threads are trying
to unwind at the same time since the global signal lock is held for
only a small amount of time. Even running through the threads one at
a time should be faster since it no longer requires two passes through
the unwound stacks.

The new code now allows multiple simultaneous unwinds of the
same thread.

Finally, add the ability to unwind from a ucontext_t passed in. This
functionality doesn't work for remote unwinds yet.

Add new tests to check for leaks.

Refactor the BACK_LOGW code into a single header file.

46756821c4 Rewrite libbacktrace to be all C++. 
This includes removing the map_info.c source and replacing it with the
BacktraceMap class to handle all map related code.

Change all callers of libbacktrace map functionality.

Also modify the corkscrew thread code so that it doesn't need to build
the map twice (once in the corkscrew format and once in the libbacktrace
format).

20303f856f Next phase of the move, reformat use C++ features. 
Use the libbacktrace C++ interface instead of the C interface in debuggerd.

Reformat the debuggerd code to be closer to Google C++ style.

Fix all debuggerd casts to be C++ casts.

Add a frame number to the frame data structure for ease of formatting and
add another FormatFrameData function.

Change the format_test to use the new FormatFrameData function.

Modify all of the backtrace_test to use the C++ interface.

of the current process at the same time.

17e91d44ed Rewrite libbacktrace using C++. 
The old code was essentially trying to be C++ in C and was awkward. This
change makes it all objects with a thin layer that C code can use.

There is a C++ backtrace object that is not very useful, this code will
replace it.

This change also includes moving the backtrace test to a gtest, and adding
coverage of all major functionality.
