Remove the mips ucontext definition, there is no need for it any more.
Fix the mips/x86 ucontext copy code to copy the entire uc_mcontext data
across.
Fix a potential memory leak too.

We're seeing major stack trace generation performance
regression and want to find out whether it's libunwind.

In order to be explicit in the Backtrace::Create() calls, adding a couple
of defines and some comments to describe what they mean.

Included in minor fix ups is the addition of a warning macro to replace
all of the ALOGW calls.

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.

- Add a wait for stop to backtrace_test. There is a possible race
condition that is exposed when using libunwind.
- Fix a few calls to unwind function calls.

This library will be used to abstract away getting backtrace
data from how it is implemented. This is the first step to
replacing libcorkscrew with libunwind.
