Convert futex to cond wait.
Switch to the better supported pthread_cond to handle the Wait/Wake
functions.
Also, increase the number of simultaneous threads in the thread tests.

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.

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.

Use real time signal for threads instead of SIGURG.
This guarantees that any application is not also using this signal
for some other purpose.

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).

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.
