8f296fb815 Transmit: do not exceed MTU for audio with encryption 
Encryption overhead (nonce etc.) was not taken into account when
computing package sizes.

13b448514a Partially fixed packet splitting 
This partially reverts a0cc3db5.

Fixes command: uv -t testcard:1920:1080:25:RGBA --param decoder-use-codec=UYVY -d sdl

The selection of correct split is quite tricky because even though 4 is
suffiecient for RGBA, using the UYVY decoder increases the size to 8
because the line-decoder obviously needs to process 2 pixels (aligned
at 2-pixel boundry). So the sender has no prior knowledge which
splitting the receiver requires.

Currently it is only a workaround using LCM from a value 48 (suitable
for RG48->R12L conversion) and pixel format block size.

9c7b18f117 Traffic shaper: use adapive capped bitrate 
Use adaptive capped bitrate if a limit bitrate value is specified.
Previously packets were emitted exactly at the specified bitrate which
is now an optional. Now, by default, the shapper shapes equally to
a frame time or capped bitrate (if the packet rate would be lower).

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.

315749bbe5 RTP: fix sending of RFC-compilant OPUS stream

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
