a0cc3db591 Transmit: correctly split packets 
Correctly split packets for different pixel formats - previously there
was preset 48 B boundary which was least common multiple for then
present pixel formats (v210 has 16, RGB 3). However, R12L is not covered
since it uses block of 36 bytes.

From now on, we are splitting the packets according to the needed
boundary of pixel format (or arbitrarily for compressed). As a side effect,
the packets may be slightly bigger up to MTU size.

384f6ef97f Transmit: same buf. number for all substreams

payload header.

baf069b7c5 H.264 std: simplified a bit 
Note that RTCP SR are now send slightly in a different way - previously
the timestamp used was T-1.

9f6048e144 Added RFC 2435 compliant RTP JPEG transport 
Compliant JPEGs can be now sent with SDP or RTSP.

315749bbe5 RTP: fix sending of RFC-compilant OPUS stream 
RTP timestamp was incorrectly computed from data_len/bps which confused VLC.

+ some cleanup

f0c99a4005 Readded SDP 
* Since RTSP is no longer working with current LIVE555, RFC-conforming
  H.264/A-law/u-law/OPUS streams can be accessed with SDP.
* experimental only (would need more effort to be robust, well written
  etc.)
* removed ifdefs from transmit relating to standard AV RTP payload
  formating
* main: added --protocol option (shortcut for --audio-protocol and
  --video-protocol)
* main: disable intra refresh in default setting for H.264 in RTSP/SDP

eabc29d956 Encryption: use CFB instead of CTR 
* implemented CFB + switched to it because Debian currently does not
  include CTR mode
* use CFB by default (decoder should still be able to decompress CTR if
  support is compiled in)

d12f9932b6 Transmit: packet rate changes 
* video: compute packet rate from actual (average) size of packet, not
         MTU, because it may be different from MTU when using FEC to
         align the size to size of FEC symbol
* audio: disable traffic shaping at all
