The shadow memory initialization in `tsan_platform_mac.cc` needs to be updated to also initialize the meta shadow and to mprotect the memory ranges that need to be avoided.  This patch moves most of the Linux implementation of `InitializeShadowMemory`, `ProtectRange` and `CheckAndProtect` into `tsan_rt.cc` so it can be reused on OS X as well.
