Factor the common code out of cf_free and mz_free.
...
Introduce the mac_ignore_invalid_free flag (0 by default) which makes both cf_free and mz_free ignore invalid free invocations and leak memory.

Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
...
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

[Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).
