Support broadcast destination for udp protocol

Use the required socket option SO_BROADCAST to be able to stream to a broadcast
address.

Prior to the patch, trying to stream to a broadcast address was resulting to the
following error:

av_interleaved_write_frame(): Permission denied

The patch has been tested with:

ffmpeg -f v4l2 -framerate 30 -input_format yuyv422 -video_size 640x480 -i /dev/video0 \
 -c:v libx264 -profile:v high -preset ultrafast -tune zerolatency -b:v 500k -pix_fmt yuv420p \
 -f mpegts udp://192.168.1.255:5004?broadcast=1

I have added an option to let the user explicitly request broadcast in order to avoid
ffmpeg to broadcast unintentionally.

Support raw dvdsub palette as stored on normal dvd's

This is how the palette is stored on dvd's. Currently
only xbmc passes the palette information to libavcodec
this way.
Check return value of avio_seek and avoid modifying state if it fails

The code still modifies state if the timestamp is not found. Not
sure exactly how to avoid that.
asf hacks
if av_read_packet returns AVERROR_IO, we are done. ffmpeg's codecs might or might not handle returning any completed demuxed packets correctly
added: Ticket #7187, TV Teletext support for DVB EBU Teletext streams
Don't accept mpegts PMT that isn't current
Don't reparse PMT unless it's version has changed
Read PID timestamps as well as PCR timestamps to find location in mpegts stream
Get stream durations using read_timestamp
changed: allow 4 second skew between streams in mov before attempting to seek
