libavformat: Remove FF_NETERRNO()

Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR()
error codes. Provide fallback definitions of other errno.h network
errors, mapping them to the corresponding winsock errors.

ffserver: set the sample aspect ratio

Hi.

It seems that ffserver sets sample_aspect_ratio to an invalid value and lavf
rejects it.

I am not sure what I am doing here, but the attached patch actually solves
something: using the following config:

CustomLog -
NoDaemon
RTSPPort 5454
<Stream test1-rtsp.mpg>
Format rtp
File "/tmp/test1-rtsp.mpg"
</Stream>

it allows a somewhat old ffplay (unaffected by the content-base issue I
spoke of in another thread) to play the stream.

Without it, ffserver logs this and closes the stream:

Wed Feb 16 14:52:14 2011 [rtp @ 0x1399de0]Aspect ratio mismatch between encoder and muxer layer

Pass VBV delay to the calling application via ctx

VBV delay is useful for T-STD compliance in some TS muxers. It is
certainly possible to retrieve it by parsing the output of FFmpeg, but
getting it from the context makes it simpler and less error-prone.
