The os.c was added by august while porting gmerlin-avdecoder to windows.
I just found another problem: For the semaphores, the implementation is missing
as well. For linux, we can use the system supplied semaphores. But for OSX,
the sem_* functions are present but non-working. This basically means
that using RTSP on OSX doesn't work right now.
So if someone finds a GPLed semaphore implementation, that would be great as
well (sometimes I feel like I'm the only one who uses semaphores at all).

Yes, if you find a GPLed drop-in replacement for base64 en-/decoding, that
would be great.

base64 is used for http authentication and some RTSP variants, so these should
work afterwards.
