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.

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 the StepIfSignalHandler function to the Regs object that checks
if the code is in a signal handler.
- Add tests for new code, also add a test that unwinds through a signal
handler.
- Slight modification to Elf to fail if a bad machine type is encountered.
Add tests for this.
Bug: 23762183
Test: Ran unit tests.

- 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.
