Also add a comment to the GetElf function to indicate that it never returns
nullptr.
Also needed to add this library to the a million and one places that the vndk
has hard-coded this data.
Bug: 23762183
Test: Built, nothing uses the new code.
Test: However, I did run backtrace_test using this code, and all tests pass.

(cherry picked from commit dc4104b720)
The StepIfSignalHandler code reads from the process memory object, which
is currently the slowest way to read memory. Change the code to read from
the elf memory object which will almost always be a memory mapped file and
should be really fast.
Also, move the tests for StepIfSignalHandler to its own file.
Bug: 23762183
Test: Unit tests pass.

- Add namespace unwindstack everywhere so that it's easier for other
code to use the library.
- Move some of the header files into include/unwindstack so that they
can be exposed.
- Modify the headers so that only a limited number need to be exposed.
- Update the tools to use the new headers.
- Add a GetLoadBias() call on the Elf object. This prevents the need
to get the interface object out of the Elf object.
- Move the GetRelPc() call out of the Reg class, to the Elf class. It's
not always the case that a Reg object will be around when you want to
get a relative pc. The tests for this moved to ElfTest.cpp.
Bug: 23762183
Test: Unit tests pass.

- Cleanup the blueprint file a bit.
- Fix the formatting in DwarfMemoryTest.cpp.
- Fix the misnamed test MemoryBuffer.cpp to MemoryBufferTest.cpp.
- Add a function to find the location of the test files so it's not
necessary to run the test in the same directory as the test files.
Bug: 23762183
Test: Builds and unit tests pass.

- Use the CHECK macro everywhere that assert was used.
- Remove the _debug version of the tests and leave the CHECK macro so
it's always checking in the code.
