Currently we use very common names for macros like ACQUIRE/RELEASE,
which cause conflicts with system headers.
Prefix all macros with SANITIZER_ to avoid conflicts.

Currently we don't lock ScopedErrorReportLock around fork
and it mostly works becuase tsan has own report_mtx that
is locked around fork and tsan reports.
However, sanitizer_common code prints some own reports
which are not protected by tsan's report_mtx. So it's better
to lock ScopedErrorReportLock explicitly.

Enable clang Thread Safety Analysis for sanitizers:
https://clang.llvm.org/docs/ThreadSafetyAnalysis.html
Thread Safety Analysis can detect inconsistent locking,
deadlocks and data races. Without GUARDED_BY annotations
it has limited value. But this does all the heavy lifting
to enable analysis and allows to add GUARDED_BY incrementally.
