150ddbc148 Do not memcpy raw video frames when using null muxer 
Commit 035af99 made avconv always call an encoder when using the
null muxer.  While useful for 2-pass encodes, it inadvertently
caused an extra memcpy of raw frames when decoding only.

This hack restores the old behaviour when only decoding while
allowing use of the null muxer with encoded streams as well.

7bb3e62594 avconv: make copy_tb on by default. 
I.e. on streamcopy set output codec timebase from input stream timebase
(as opposed to input codec timebase). This should be more sane, because
since the stream is not decoded, the input codec tb has no relation to
the timestamps of the copied packets.

aa38cff2c6 avconv: fix segfault at EOF with delayed pictures 
At EOF it makes no sense to modify avpkt.{data,size} in output_packet
since no data is consumed. Frame threading with more than 1 threads
hits the segfault.

af8ad892bf avconv: use the same behavior when decoding audio/video/subs 
I.e. if the packet was only partially consumed, pass the rest of it into
the decoder again.

Also simplify the code so it's the same for video/audio/subs.

776f2bb91a Call avformat_network_init/deinit in the programs 
Calling the init function will become mandatory at some later
point. By calling it, more heavy network init (such as SSL/TLS
library init) can be done once at startup, instead of implicitly
when used (which could lead to it being done a number of times).

d0a196962a g722dec: remove the use of lowres for half-rate decoding. 
It is broken because an AVCodecContext can be opened/closed multiple
times, and sample_rate is getting divided by 2 each time that happens.

This removes the only use of lowres for audio.

Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.
