Add a new option 'rtmp_flush_interval' that allows specifying the
number of packets to write before sending it off as a HTTP request.
This is mostly relevant for RTMPT - for plain RTMP, it only controls
how often we check the socket for incoming packets, which shouldn't
affect the performance in any noticeable way.

This seems to be the correct mode to send, according to the
original RTSP RFC, and matches the method RECORD which is
sent later when starting to send data.
Darwin Streaming Server works fine with either of them.

This requires all NAL units to fit within single RTP packets. It
doesn't change the actual packetization for packets that fit, but
errors out and gives a helpful hint if the NAL units would have to
be split, and signals the right packetization mode in the SDP.

This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPT protocol implementation uses rtmphttp:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.

Defining restrict results - for some compilers - in changing other
uses of the restrict keyword also, e.g. __declspec(restrict) gets
changed to __declspec(__restrict) on MSVC. This causes compilation
failures. Therefore, using a private namespace macro instead is
more reliable and robust.

This makes sure all incoming packets are read and handled (and reacted
to) while sending an FLV stream over RTMP to a server. If there were
enough incoming data to fill the TCP buffers, this could potentially
make things block at unexpected places. For the upcoming RTMPT support,
we need to consume all incoming data before we can send the next
request.

While there is no reason for starting a frame with anything else
than a Mode A packet, some senders seem to consistently use Mode B
packets for everything. This fixes depacketization of such streams.

Apple softwares seem not to add a tref for the timecode (the next commit
fixes this issue), but at least FFmpeg does.
This can be used to generate a sample that demonstrates the feature:
./ffmpeg -f lavfi -i testsrc \
-f lavfi -i mptestsrc \
-f lavfi -i rgbtestsrc \
-map 0 -map 1 -map 2 \
-metadata:s:0 timecode=00:00:00:12 \
-metadata:s:2 timecode=01:02:12:20 \
-t 10 -y out.mov
./ffprobe out.mov
The timecode metadata being transmitted to the video streams, it can be
kept while transmuxed/transcoded.

Some demuxers set a timecode in the format or streams metadata. The
muxers now make use of this metadata instead of a duplicated private

This makes possible transparent copy of the timecode when transmuxing
