[tsan] locate the auxilary space for tsan's Allocator64 after the main region, not before. This simplifies the shadow mappings

[ASan] fix flakiness of Linux-specific clone_test: waitpid should better be provided with __WCLONE option, otherwise it didn't wait for the subprocess, returned -1, and we went crushing the subprocess stack

For invalid pointers passed to free_common check whether they are actually skewed to hold an additional CFAllocatorRef.
If so, fix the pointer and pass it to asan_free.

See http://code.google.com/p/address-sanitizer/issues/detail?id=70 for more background.

library.

These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.

I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.

I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.

The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:

  <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
  <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
  <prefix>/lib/clang/X.Y/include/sanitizer/...

But maybe others have different suggestions?

Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.

Finally, it switches to the proper flag -rdynamic.

With this, the cmake build is warning free on my bootstrap Linux build.
