Dmitry Vyukov 8df3c7ded2 sanitizer_common: sanitize time functions
We have SleepForSeconds, SleepForMillis and internal_sleep.
Some are implemented in terms of libc functions, some -- in terms
of syscalls. Some are implemented in per OS files,
some -- in libc/nolibc files. That's unnecessary complex
and libc functions cause crashes in some contexts because
we intercept them. There is no single reason to have calls to libc
when we have syscalls (and we have them anyway).

Add internal_usleep that is implemented in terms of syscalls per OS.
Make SleepForSeconds/SleepForMillis/internal_sleep a wrapper
around internal_usleep that is implemented in sanitizer_common.cpp once.

Also remove return values for internal_sleep, it's not used anywhere.

Eventually it would be nice to remove SleepForSeconds/SleepForMillis/internal_sleep.
There is no point in having that many different names for the same thing.

Amy Huang 9ba623c655 [asan] Add %d variable to external_symbolizer_path option, so that user can specify paths relative to the location of the binary.
We want way to set a path to llvm-symbolizer that isn't relative
to the current working directory; this change adds a variable that
expands to the path relative to the current binary.
This approach came from comments in https://reviews.llvm.org/D93070

Dmitry Vyukov 5f149ef51f compiler-rt: allow golang race detector to run on musl-c
tsan while used by golang's race detector was not working on alpine
linux, since it is using musl-c instead of glibc. Since alpine is very
popular distribution for container deployments, having working race
detector would be nice. This commits adds some ifdefs to get it working.

It fixes https://github.com/golang/go/issues/14481 on golang's issue tracker.

Nico Weber 65492d959b compiler-rt: Rename .cc file in lib/sanitizer_common to .cpp
See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran

  for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done

and manually updated (many) references to renamed files found by that.
