When glancing at libc.so, I noticed we had five copies of
`__fortify_fatal` sitting around. LLVM can't inline variadic functions;
allowing everything to reference the same one seems best to me. This
saves us a few hundred bytes. Whoopee.

It seems clearer to include FD_SETSIZE in the message. set_size
is sizeof(fd_set) so there's an extra mental hoop to jump if that's
in the error message.

Move all the new checks over to the existing __fortify_fatal.

This library is used by a number of different libraries in the system.
Make it easy for platform libraries to use this library and create
an actual exported include file.
Change the names of the functions to reflect the new name of the library.
Run clang_format on the async_safe_log.cpp file since the formatting is
all over the place.

Our FORTIFY _chk functions' implementations were very repetitive and verbose
but not very helpful. We'd also screwed up and put the SSIZE_MAX checks where
they would never fire unless you actually had a buffer as large as half your
address space, which probably doesn't happen very often.
Factor out the duplication and take the opportunity to actually show details
like how big the overrun buffer was, or by how much it was overrun.
Also remove the obsolete FORTIFY event logging.
Also remove the unused __libc_fatal_no_abort.
This change doesn't improve the diagnostics from the optimized assembler
implementations.
