* match a couple h264-reader semantic changes. E.g., decode_nal now
expects the full NALU including header byte.
* adjust test data in depacketize_parameter_change. The SDP parameters
I used were invalid in a way caught only by the new h264-reader crate.
That's not the intended scenario, so use different parameters. But
mention the accidental scenario in CHANGELOG.md.
* initialize logging in h264 tests to ease debugging problems like the
bullet above.
* in AAC code, match h264-reader's switch from bitreader to
bitstream-io. This keeps dependencies down, in addition to the reasons
for h264-reader's switch, described here:

As described in #47 and #58: revamp this type to keep the full raw
packet, and provide accessors rather than raw fields. It's also
smaller now, which is nice.
As listed in #47.
This improves throughput in the client/h264 benchmark by about 20%,
I think because we copy fewer bytes around. CodecItem went from 256
bytes to 176.
Found by inspection. It'd be nice to fuzz the tokio module to more
reliably find problems like this, but it looks like I'd have to make
a bunch more stuff public for that. Maybe later...
It's allowed for a server to send only in-band parameters, although I
haven't encountered this yet. The VStarcam cameras sometimes send
invalid out-of-band parameters; treat that as if it sent nothing.
Fixes#42
* out-of-order packets should be ignored (except for logging).
* after ignored RTP or RTCP packet, don't incorrectly return Pending
without both underlying sockets actually returning Pending. This
could lead to not rechecking the sockets until prompted for another
reason, like an RTSP keepalive.
This was an attempt at #17 that didn't work out. Besides additionally
hitting the framing error, my Reolink test camera never timed out
the old session while the new one was in progress. This behavior is
different than the vanilla 2013.04.06 live555 server, so apparently
Reolink sprinkled in their own brokenness on top. In any case,
the other solutions described in that bug are more likely to work.
There's one narrow case I want to keep working: ignoring RTCP messages
immediately prior to the PLAY response. More recent Reolink cameras
do this. I just have this behavior on all the time now.
* support setting transport to UDP
* breaking change: use new PacketContext rather than RtspMessageContext
in places where an RTP/RTCP packet is expected, as it can now be over
UDP instead of via RTSP interleaved data
* send teardown, which is important with UDP sessions. (It also will
help somewhat with Reolink TCP.) Along the way, make Session Unpin
so that teardown can consume it without tripping over tokio::pin!().
* refactor to shrink the amount of data used by Session and how much
gets memmoved around on the stack, instead of further growing it.
Because of missing RTCP RR and reorder buffer support, this is only
appropriate for using on a LAN. That's enough for me right now.
