Also delete some fdsan code that attempts to check for the post-fork
state, but never will, because we update the cached pid upon fork.

I'm assuming this was useful while debugging, but isn't needed now.

accept creates an additional socket behind the scenes to communicate
with netd. Filter out events for temporarily created, but then closed
fds to allow for this.

Add tests for all of our existing wrappers (with one commented out,
because it's unexpectedly generating multiple events).

Add a hook that's called upon file descriptor creation to libc, and a
library that uses it to capture backtraces for file descriptor creation,
to make it easier to hunt down file descriptor leaks.
Currently, this doesn't capture all of the ways of creating a file
descriptor, but completeness isn't required for this to be useful as
long as leaked file descriptors are created with a function that is
tracked. The primary unhandled case is binder, which receives file
descriptors as a payload in a not-trivially-parsable byte blob, but
there's a chance that the leak we're currently trying to track down
isn't of a file descriptor received over binder, so leave that for
later.
