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.

in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.

[Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

[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.
