Changes
- Refactor the code so that only guards require creating a special header
for every pointer allocated.
- Store only a single copy of every backtrace. This saves memory so that
turning on the backtrace option doesn't result in 10X memory usage.
- Added new option track_allocs that only verifies pointers are valid for
free/malloc_usable_size/realloc.
- Remove suffix from test names.
- Add the TRACK_ALLOCS options to all guard options.
- Add new option verify_pointers that is a lightweight way to verify
pointers that are passed to allocation routines.
- Do auto-formatting of the code.
- Updated documentation for all of these changes.
Bug: 74361929
Test: Ran unit tests.
Test: Ran libmemunreachable unit tests.
Test: Ran an app with backtrace enabled.
