[PATCH] tsan: ignore interceptors coming from specified libraries

[Dmitry Vyukov]

  Added to the description:

  Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib, then must call our internal allocator instead of libc malloc.
