- The pc read from the eh frame binary table of pc/fde offset is off by 4.
I verified that on arm/arm64/x86/x86_64 the pc in this table matches
the fde pc_start value. I did this by adding an error if this occurred
and ran unwind_info over everything in system/lib, system/lib64, system/bin.
- Fixed unit tests for the above change.
- Fix a small bug in the processing encoded values. The high
bit of the encoding should be masked off, but I wasn't doing that. That
meant during processing of the fde, I was incorrectly returning
an error because the encoded value was unknown.
- Added a new test for this encoding change.
Bug: 23762183
Test: Build and all unit tests pass. Also, see above comments.

- 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.

- 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.
Bug: 23762183
Test: Ran unit tests.
