Convert abort's inline_tgkill to do the equivalent of
pthread_sigqueue(pthread_self(), ...), so that we can use it in fdsan
as well.

to allow users to get and interpret the tags.

libc had some -Wimplicit-fallthrough warnings. They all seem to be
benign. We're trying to enable this flag globally, so we need to
annotate these breaks here.

Let the debuggerd handler get the address of the fdsan table so that
crash_dump can parse it and print it out in tombstones.

Make it easier for other code to parse the fdsan table themselves by
making it so that they can include the bionic_fdsan.h header to get a
struct definition with the layout without bringing in other
dependencies.

Add handling for all 4 cases of failure of exchange_owner_tag. Also,
mask off and sign extend the type byte of the owner tag, and add a
test for that.

Generate a tombstone instead of just a log message when warning. Also,
don't use async_safe_fatal_va_list when we're not calling abort, as
this will permanently set the abort message.

Add two functions to allow objects that own a file descriptor to
enforce that only they can close their file descriptor.
Use them in FILE* and DIR*.
