Replaces libbacktrace in CallStack. There is one small behavioral
change, the BuildId data is added to the unwinds.
Bug: 120606663
Test: All unit tests pass.
Test: Run the fuzzer for over an hour without any crashes.

This reverts commit b9d0753d2b.
Reason for revert: Re-land with MacOS workaround.
Test: Build (on Linux) and boot AOSP, with weak symbols enabled and disabled.

This reverts commit 9d3146af22.
Reason for revert: It appears that weak symbols don't work as expected on MacOS, breaking the MacOS aapt build.

Move towards crashing if a normally configured RefBase object is
destroyed without ever incrementing the reference count. We've been
threatening to do this for a long time. The previously last known
violation had been fixed.
This also fixes stack trace printing from RefBase, which had previously
been broken, and which we found necessary to track down further
violations of this rule.
Unfortunately, we found several more violations with the aid of
that fix. After existing CLs are submitted, there are
still some failures, but they are no longer numerous. Thus this CL
doesn't actually crash in the event of a violation, but does log a
verbose stack trace if it encounters one.
Bugs have been filed against the remaining known RefBase client offenders.
We plan to enable crashing on usage violations once those are fixed.
The fix for the stack trace printing breakage unfortunately requires
the use of weak symbols in order to avoid a circular build dependency.
We expect to eventually replace this with execinfo.h functionality.
Some random reformatting, driven by consistency with current formatting
requirements.
Add missing include to BacktraceMap.h.

These warnings are triggered by -Wextra-semi (and not -Weverything, as
incorrectly mentioned in I49b6e6af483e011632e6a34c0663c93e5c385aa6).
This warning is added to Hidl-generated libs.
To appease clang-format, this patch also fixes some extra newlines.
Test: Build

Moved headers from include/libutils and include/libsysutils to
libutils/include and libsysutils/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Moved headers of libutils to libutils_headers. They should be used
by modules for header-only inlines. Added libutils_headers as
dependency of libutils.
Split of C++ headers into those that have no dependency and those that
have dependency on libutils.so will be handled in a later CL.
Test: Add above libs to shared lib of local module
