The CHECK(encoding != DW_EH_PE_aligned) can trip given the right
arguments. This check isn't necessary, since the code will return
false in that case.
Add new unit test that tries all values to make sure no CHECK fires.
Bug: 120968571
Test: Passes new unit test, and passes fuzzing that failed before.

Rename Memory::Read to ReadFully to match its semantics with that of
android::base. ReadPartially will be renamed to Read in a follow up
commit, kept intentionally separate so that there aren't any callers
accidentally switched from ReadFully to Read.

- 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.

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.
