(which, in turn, is required for our interceptors to take effect), re-exec the program with

tsan: fix new memory allocator
...
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.

Re-implement the wrappers for libdispatch functions using blocks where appropriate
...
(kudos to Anna Zaks for a good example).
This simplifies the code much and lets us not implement internal parts of libdispatch.
All ASan tests from t32 and t64 should pass with the dylib runtime now.
