Dmitry Vyukov e9a5f03716 tsan: support mmap(MAP_32BIT) 
Allow user memory in the first TB of address space.
This also enabled non-pie binaries and freebsd.

Dmitry Vyukov 65dce1e4f7 tsan: write memory profile in one line (which is much more readable) 
e.g.:
RSS 420 MB: shadow:35 meta:231 file:2 mmap:129 trace:19 heap:0 other:0 nthr=1/31
RSS 365 MB: shadow:3 meta:231 file:2 mmap:106 trace:19 heap:0 other:0 nthr=1/31
RSS 429 MB: shadow:23 meta:234 file:2 mmap:143 trace:19 heap:6 other:0 nthr=1/31
RSS 509 MB: shadow:78 meta:241 file:2 mmap:147 trace:19 heap:19 other:0 nthr=1/31

Dmitry Vyukov bde4c9c773 tsan: refactor storage of meta information for heap blocks and sync objects 
The new storage (MetaMap) is based on direct shadow (instead of a hashmap + per-block lists).
This solves a number of problems:
 - eliminates quadratic behaviour in SyncTab::GetAndLock (https://code.google.com/p/thread-sanitizer/issues/detail?id=26)
 - eliminates contention in SyncTab
 - eliminates contention in internal allocator during allocation of sync objects
 - removes a bunch of ad-hoc code in java interface
 - reduces java shadow from 2x to 1/2x
 - allows to memorize heap block meta info for Java and Go
 - allows to cleanup sync object meta info for Go
 - which in turn enabled deadlock detector for Go

Dmitry Vyukov 8d1eb705c7 tsan: add support for passing file descriptors over UNIX domain sockets 
tsan was missing new fd's arrived from recvmsg(),
and thus was reporting false positives due to missed synchronization on the fd's

Dmitry Vyukov 464ebbd67b tsan: move shadow stack from thread descriptors to fixed addresses 
This allows to increase max shadow stack size to 64K,
and reliably catch shadow stack overflows instead of silently
corrupting memory.

Dmitry Vyukov 302ec7b9bc tsan: add memory_limit_mb flag 
The flag allows to bound maximum process memory consumption (best effort).
If RSS reaches memory_limit_mb, tsan flushes all shadow memory.

Sergey Matveev 954c6ef10f [sanitizer] Move GetThreadStackAndTls from TSan to sanitizer_common. 
Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).

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.
