c56a499422 Only skip frames for local unwinds.
When doing a remote unwind, and there is a crash in the unwind stack
code or in libbacktrace, the old version would skip those frames.
This makes debugging crashes in those libraries a bit difficult.

Bug: 68820611

Test: Ran unit tests.
Test: kill -3 a zygote process and verify no frames in
Test: libunwindstack.so/libbacktrace.so.
Test: Forced a crash in libunwindstack.so and verified the tombstone
Test: contains the full crash.

086baf981d Switch libbacktrace new unwinder.
Update the backtrace leak tests to share a map since this is the most
common way it will be used, and it runs much faster.

Remove the CreateNew functions, and references to them.

Remove benchmarks of CreateNew functions.

Test: Builds, ran new unit tests, ran art tests.

b63a60fe83 libbacktrace: make Backtrace::FormatFrameData static.
Backtrace::FormatFrameData doesn't depend on anything from its
instance. Make it static so that callers that don't have a Backtrace*
available can format frames.

Test: mma

6f3981c181 Add support for the new unwind method.
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.

96722b0fa4 Cleanup the libbacktrace interface a bit.
- Change the field name load_base to load_bias (which is what it really is).
- Add a rel_pc field so that callers do not need to compute it themselves.
- Remove the BacktraceMap::GetRelativePc() since nobody should need to
  compute this themselves.

Bug: 23762183

Test: Compiles and unit tests pass (debuggerd, libbacktrace).
