There is a hang when enabling leak_track since the dumping of the
leak data can wind up doing an allocation.
Add new system unit test to make sure this doesn't happen again.
Bug: 111146059
Test: Test program that leaks does not hang forever.
Test: Unit tests pass.

Bump the version from v1.1 to v1.2 and add a build fingerprint line.
Update the heap dump documentation to match the new format and reflect
what made it in P and what made it in Q.
Update the unit tests for this change.
Add -O0 to unit test code to make it easier to debug.
Add an external function that can be used by the framework code
so that there is only one way to dump the heap.
Bug: 110095681
Test: Ran unit tests.
Test: Did a dump of a real process and verified fingerprint.
Test: Did a dump of a process without malloc debug enabled.

(cherry picked from commit c84a2a2601)
This adds a new option backtrace_full, when it is set, then it will use
libunwindstack.
Modify the dump to file data to dump the extra information from libunwindstack.
Along with the new dump file format, change the version to v1.1.
Updated document for new format of file data.
Add unit tests for the new functionality.

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.

This library is used by a number of different libraries in the system.
Make it easy for platform libraries to use this library and create
an actual exported include file.
Change the names of the functions to reflect the new name of the library.
Run clang_format on the async_safe_log.cpp file since the formatting is
all over the place.
Bug: 31919199
Test: Compiled for angler/bullhead, and booted.
Test: Ran bionic unit tests.
Test: Ran the malloc debug tests.
Change-Id: I8071bf690c17b0ea3bc8dc5749cdd5b6ad58478a
Previously malloc debug can be enabled only using global settings
accessible to the root user only. This CL adds a new option to enable
it using environment variables making it possible to use it with pure
native (shell) applications on production builds (from shell user) and
prepares it for using it from logwrapper on production devices.
Remove the old environment variable and property since they are not
necessary.
Test: Enable malloc debug using environment variable and verify
Test: that it only affects the commands launched from the shell.
Test: Enable malloc debug using the property variable and verify
Test: that it affects all commands.
Test: Run all unit tests in 32 bit and 64 bit.
