Alexey Samsonov 51ae983718 [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).

Dmitry Vyukov 7fb7330469 asan/tsan: weak interceptors 
The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc

Alexander Potapenko ec316e5940 Partially revert r154390 (http://llvm.org/viewvc/llvm-project?view=rev&revision=154390) 
Until we work out the solution for http://code.google.com/p/address-sanitizer/issues/detail?id=65 we'd better not allow
the clients to override AddressSanitizer's signal handler.

The second part of r154390 (removing the sighandler-related tests) is not reverted, because those tests were broken
and didn't test anything.

Alexander Potapenko bc42d44112 Change the way ASan interacts with custom signal handlers. 
From now on we allow the clients to override signal handlers set by ASan, but print a warning in such a case.

Remove the tests for signal() and sigaction(), because they made little sense even without this change.
