Anna Zaks 8d225205e3 [asan] Fix the deadlocks introduced by "On OS X, log reports to syslog and os_trace" commit 
[asan] On OS X, log reports to syslog and os_trace, has been reverted in r252076 due to deadlocks on earlier versions of OS X. Alexey has also noticed deadlocks in some corner cases on Linux. This patch, if applied on top of the logging patch (http://reviews.llvm.org/D13452), addresses the known deadlock issues.

(This also proactively removes the color escape sequences from the error report buffer since we have to copy the buffer anyway.)

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.

Directory structure:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan runtime library.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between various sanitizers.

ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).

ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:

make check-asan
