Change the recent h264_mp4toannexb bitstream filter test to output to an elementary stream rather than a program stream.
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

The fate reference is updated because the previous test skipped a sample in
each encode() call due each input frame having an odd number of samples.

The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly)
a MpegEncContext in their private context. Since they do not call the
common mpegvideo init function slice_context_count has explicitly set
to 1.
Prevents a null pointer dereference in the h264 parser and fixes
bug 193.

Prevents a division by zero.

Prevents null ptr derefence for negative sizes.

The implicit network initialization is set to be removed in the
future, but is kept for compatibility. By not doing the implicit
initialization for non-network protocols, we avoid the warning
about avformat_network_init() not being called for these, where
it really doesn't make much sense.
