Justin Bogner ad560c4c11 CMake: Enable -Werror for the -fno-function-sections check 
If the -fno-function-sections flag isn't recognized, the compiler
emits a warning. This isn't enough to cause the check to fail, so we
enable -Werror as well.

Alexander Potapenko 2e7dc60ee3 [ASan] Replace the call to "vname" with "WRAP(vname)" in FORMAT_INTERCEPTOR_IMPL 
It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.

This patch fixes asan/lit_tests/TestCases/printf-3.c on Mac.

Dmitry Vyukov 8aaa44c43d tsan: relax check for errno spoiling more 
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

Sergey Matveev c18b36625e [sanitizer] Partial revert of recent ioctl changes. 
Some build environments are missing the required headers.
This reverts r200544, r200547, r200551. This does not revert the change that
introduced READWRITE ioctl type.
