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 6cfab724ec tsan: refactor deadlock detector 
Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.

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.
