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.

Create an UnwindMapLocal object.
The way libunwind handles local unwinds is different from remote unwinds,
so create a new map object to handle the differences.
Add new test to verify the map data is being generated correctly.
Add new tests to check for leaks.
Refactor the BACK_LOGW code into a single header file.

Re-enable libunwind for arm.
Update to handle the new optimized way that libunwind works.
In addition, a small refactor of the BacktraceMap code.
A few new tests of for good measure.

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).

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.

Refactor to share map_info amongst threads.
Allow the use of the same map info to be shared when getting information on
multiple threads from the same pid.

More libbacktrace fixes.
Included in minor fix ups is the addition of a warning macro to replace
all of the ALOGW calls.
Fix a race where multiple threads could be attempting to unwind the threads
of the current process at the same time.

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.
