ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Fri Aug 18 13:02:19 2023 -0300| [8c789c5da3ce9dd721fb0ec14927c3809eca446d] | committer: James Almer

avutil/thread: add wrappers for pthread_cond_t functions

This abstraction is similar to the existing one for pthread_mutex_t and
pthread_once_t functions, and should reduce the amount of ifdeffery used
in future code.
