Dmitry Vyukov 16e7a758b0 tsan: do not deadlock on fork
Currently correct programs can deadlock after fork, because atomic operations and async-signal-safe calls are not async-signal-safe under tsan.
With this change:
- if a single-threaded program forks, the child continues running with verification enabled (the tsan background thread is recreated as well)
- if a multi-threaded program forks, then the child runs with verification disabled (memory accesses, atomic operations and interceptors are disabled); it's expected that it will exec soon anyway
- if the child tries to create more threads after multi-threaded fork, the program aborts with error message
- die_after_fork flag is added that allows to continue running, but all bets are off

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).

Alexey Samsonov 25d010a98d [Sanitizer] Always initialize a Symbolizer (even if 'symbolize' is false).
If 'symbolize' flag is not set, we still want to transform virtual address
to module+offset pair in the call to Symbolizer::SymbolizeCode().
See https://code.google.com/p/address-sanitizer/issues/detail?id=251 for
more details.

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.

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).
