Joerg Sonnenberger 9d09e2fe90 Reapply r201910. MSVC gets __func__ defined explicitly, even though it 
can't build anything here.

Kostya Serebryany cf5d8e4f29 AdjustStackSizeLinux() is used in Lsan, Tsan and Msan non-Linux-specific code so it seems it should have more generic name and moved to a common scope. 
Renamed to AdjustStackSize.
Patch by Viktor Kutuzov.

Reid Kleckner 324eee45a7 Revert "Replace __FUNCTION__ with __func__, the latter being standard C99/C++11." 
This reverts commit r201910.

While __func__ may be standard in C++11, it was only recently added to
MSVC in 2013 CTP, and LLVM supports MSVC 2012.  __FUNCTION__ may not be
standard, but it's *very* portable.

Evgeniy Stepanov 05938a23f5 [sanitizer] Use mmap to zero-fill large shadow regions. 
This is covered by existing ASan test.
This does not change anything for TSan by default (but provides a flag to 
change the threshold size).

Evgeniy Stepanov 769d46f373 [sanitizer] Use system unwinder in signal handlers on Android. 
Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.

Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.
