Relocate the external headers provided by ASan and the common sanitizer
...
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.

Some flag cleanup for the sanitizer runtimes.
...
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.

[ASan] Create new files asan_report.{h,cc} as a preparation for refactoring of ASan error reporting code.
...
Currently ASan reports many kinds of errors, and the code that actually prints error messages can
be found inside allocator, OS-specific files, interceptors code etc.
An example of maintenance troubles this situation causes:
There is currently an ASan interface function that registers
callback which should take the char buffer with error report printed by ASan.
This function is now broken, as one has to insert callback calls to all the places in
ASan code where the error reports are printed, surprisingly it is not only
"__asan_report_error" function...
