0d07dcc241 Make the unit tests isolated. 
Modify the tests that require a single filename, to use a filename
that has the pid as part of the name. This allows multiple different
versions of the test to run on the same machine, and allows
each test to be run at the same time.

Test: Ran unit tests on device.
Test: Ran the unit tests 100 times, no failures.

Christopher Ferris
dfbc59ae51 Use new AndroidLocalUnwinder. 
The new object incorporates all Android specific knowledge into
a single place and makes everything simpler.

Fixed a bug where if backtrace_full was enabled, the AddBacktrace
function would always set the size to the maximum number
of frames instead of the actual number of frames.

Added a new smoke system tests for backtrace_full.

Modified the smoke test to do a malloc/free, so it's really
a smoke test.

Bug: 232575330

Test: Unit tests pass on device.
Test: Verify the full backtrace actually produces valid backtraces.
Test: Run bionic-unit-tests with backtrace_full enabled.
Test: Run bionic-benchmarks --benchmark_filter=stdlib_malloc_free_decay1/512

1727595b0e mntent_test: don't assume /proc isn't the first mount. 
This test tried to be lazy and test both getmntent() and getmntent_r()
in the same test, but that led to an implicit assumption that /proc
isn't the first mount returned.

This new version is quite a bit more thorough than the old. It does
assume that the mount list doesn't change while the test is running, but
that seems like a reasonable assumption to make during CTS?

b42e8b4dec Add option to force memunreachable check. 
The new option is named check_unreachable_on_signal. It is meant
to duplicate dumpsys meminfo --unreachable <PID> for non-java
processes. When enabled, a user can send a signal to a process
which will trigger the unreachable check on the next allocation
call.

Added new unit tests.

Test: New unit tests pass.
Test: Enabled for the entire system, then dumped on the netd
Test: process and also system_server.

See:
  https://man7.org/linux/man-pages/man2/close_range.2.html

Note: 'man close_range' documents 'flags' as unsigned int,
while glibc unistd.h as just 'int'.  Picking 'int' to match glibc,
though it probably doesn't matter.

f78486f40e Mangle the pointers stored in PointerData. 
The libmemunreachable library looks through memory to determine
if pointers are leaked. Unfortunately, the malloc debug code
stores the original pointer in data structures, so it looks like
pointers are still in use. The fix is to mangle the pointers
stored in memory so that it doesn't trick the library into thinking
they are live.

Test: All unit/system tests pass.
Test: Ran libmemunreachable and verified leaks show up.
