Dmitry Vyukov 5ba736457c tsan: ignore interceptors coming from specified libraries
LibIgnore allows to ignore all interceptors called from a particular set
of dynamic libraries. LibIgnore remembers all "called_from_lib" suppressions
from the provided SuppressionContext; finds code ranges for the libraries;
and checks whether the provided PC value belongs to the code ranges.

Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of
SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib,
then must call our internal allocator instead of libc malloc.

Sergey Matveev d109eb052b [tsan] Move some suppressions-related code to common.
Factor out code to be reused in LSan. Also switch from linked list to vector.

Dmitry Vyukov 19b855fe3e tsan: remove shutdown code
tsan runtime shutdown is problematic for 2 reasons:
1. others crash during shutdown
2. we have to override user exit status (don't know it and can't return from atexit handler)

Kostya Serebryany 4ad375f0a9 [tsan] First commit of ThreadSanitizer (TSan) run-time library.
Algorithm description: http://code.google.com/p/thread-sanitizer/wiki/ThreadSanitizerAlgorithm

Status:
The tool is known to work on large real-life applications, but still has quite a few rough edges.
Nothing is guaranteed yet.

The tool works on x86_64 Linux.
Support for 64-bit MacOS 10.7+ is planned for late 2012.
Support for 32-bit OSes is doable, but problematic and not yet planed.

Further commits coming:
  - tests
  - makefiles
  - documentation
  - clang driver patch

The code was previously developed at http://code.google.com/p/data-race-test/source/browse/trunk/v2/
by Dmitry Vyukov and Kostya Serebryany with contributions from
Timur Iskhodzhanov, Alexander Potapenko, Alexey Samsonov and Evgeniy Stepanov.
