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 ce3721057d tsan: remove in_rtl counter 
This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

Dmitry Vyukov 302ec7b9bc tsan: add memory_limit_mb flag
