Kostya Serebryany 809632e28e [asan] interceptors for strcasecmp and strncasecmp. patch by samsonov@google.com

Kostya Serebryany 8b981c2564 The code instrumented with ASan may have its own instance of the
mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).

The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.
The corresponding AddressSanitizer bug is

Kostya Serebryany 6bb2f1d5b5 Recently the GCD tests started failing because of the invalid size of
FakeStack on the worker threads.
This patch moves the AsanThread initialization into a separate
procedure that's called when AsanThread objects are called for worker
threads.
