Summary:
This is required for standalone LSan to work with libdispatch worker threads,
and is a slimmed down version of the functionality provided for ASan
in asan_mac.cc.
Re-commit of r305695 with use_stacks=0 to get around a racy lingering pointer.

We seem to assume that OS-provided thread IDs are either uptr or int, neither of which is true on Darwin. This introduces a tid_t type, which holds a OS-provided thread ID (gettid on Linux, pthread_threadid_np on Darwin, pthread_self on FreeBSD).

Summary:
We have a way to keep track of allocated DTLS segments: let's use it
in LSan. Although this code is fragile and relies on glibc
implementation details, in some cases it proves to be better than
existing way of tracking DTLS in LSan: marking as "reachable" all
memory chunks allocated directly by "ld".
The plan is to eventually get rid of the latter, once we are sure
it's safe to remove.

Update the main thread's os_id on every pthread_create, and before
initiating leak checking. This ensures that we have the correct os_id even if we
have forked after Init().
