We already require this XSI standard in many files in Libav.
Furthermore enabling this globally should expose necessary
functionality that gets hidden on some (BSD) systems if
_POSIX_C_SOURCE is enabled without _XOPEN_SOURCE.

-These systems will not compile out-of-the-box due to broken system headers.
-Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
