Fix http://code.google.com/p/address-sanitizer/issues/detail?id=87 by making sure we replace the default CFAllocator only after __CFInitialize has been called.

First, placement new from standard library conflicts with our own.
Second, we are in trouble if user uses the same function (we either get instrumented code in runtime, or non-instrumented code in user program).

[TSan] add a new option 'use_internal_symbolizer' that allows to choose between addr2line-based and llvm-based symbolizer w/o having to rebuild the runtime. This is hopefully a temporary solution that simplifies testing process. In the end, we should leave a single symbolizer.

These callbacks assume that the memory belongs to asan_zone, so it's incorrect to pass it to another one.
If a need for this appears (e.g. system libraries free the memory using wrong zone), it should be documented.

[Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.
