[PATCH] [Sanitizers] Intercept opendir()

[Evgeniy Stepanov]

Got it.
This interceptor is beneficial on linux, too - it adds check for opendir() path.
Also, we've been moving interceptors to sanitizer_common, not the other way around. Please move it back, and merge the TSan bits into it (see COMMON_INTERCEPTOR_FD_ACQUIRE).
