240d212822 pipewire-v4l2: disable _FORTIFY_SOURCE when defining override functions 
_FORTIFY_SOURCE defines always_inline versions of open etc. functions,
which conflict with our exported override versions.  Disable it for the
file that defines the override functions.

3ee852b808 pipewire-v4l2: More improvements 
Keep separate map for fd to files so we can implement dup.

Filter out duplicates in enumfmt.

tryfmt should return the closest match.

Use pthread_once to init the global state.

Make things mostly work in GStreamer.
