There are no actual users of the machine type output parameter to
Regs::RemoteGet. The concrete implementations of Regs know what machine
type they represent anyway, so provide an accessor to query.

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.
Bug: 23762183
Test: Unit tests pass.

- Fixes a few bugs in untested functionality.
- Add tests for the way the register handling code is used.

- 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.

This cl includes the code to read arm unwind information from a shared
library.
Bug: 23762183
Test: Passes all unit tests. I can dump the arm unwind information
Test: for an arm shared library.
