avio: Handle AVERROR_EOF in the same way as the return value 0

This makes sure the ffurl_read_complete function actually
returns the number of bytes read, as the documentation of the
function says, even if the underlying protocol uses AVERROR_EOF
instead of 0.

rmdec: Use the AVIOContext given as parameter in rm_read_metadata()

This fixes crashes when playing back certain RealRTSP streams.

When invoked from the RTP depacketizer, the full realmedia
demuxer isn't invoked, but only certain functions from it, where
a separate AVIOContext is passed in as parameter (for the buffer
containing the data to parse). The functions called from within
those entry points should only be using that parameter, not
s->pb. In the depacketizer case, s is the RTSP context, where ->pb
is null.

cmdutils: wrap exit explicitly

Some C runtime implementations deadlock when calling threading functions
on the atexit() handler.

Use a simpler wrapper similar to av_log to call the cleanup function
before exit.

The extradata is already freed by avformat_open_input on
failure.

qdm2: use init_static_data
qdm2: formatting cosmetics

Apply the usual style plus drop few unnecessary return at the end
of void functions.
qdm2: check and reset dithering index per channel

Checking per subband would have the index exceed the
dithering noise table size.

avformat_find_stream_info: fallback to timestamps in analyzeduration check in more cases

This fixes speex in rtmp
Fixes Ticket2409

the nellymoser in flv case actually needs larger analyzeduration. The code
previously just failed to calculate the duration

If this causes any problems, like premature analyze/probe end, please report!
