revid: general bug fixing
...
Use http instead of https in gvctrl getLogin request. Gave RTP client a close method so that the conn can
be closed after we're done with the client. Put timeout on reading from the RTP client PacketConn so that
we don't hang on the ReadFrom call if the conn is closed. Closing the RTSP and RTP clients when
startRTSPCamera is returned.

fixed bugs causing problems with GeoVision H264 RTMP to youtube streaming.
...
Two fixes were involved, firstly, access unit delimeters were used to denote access units and the Write timeout on rtmpSender's ringBuffer was
increased to stop the 'unable to dump old write' errors. Also made some small changes elsewhere that should fix future issues, particular with
MTS output.

codec/h264/h264dec/fuzz: added fuzzer test for parseLevelPrefix function
...
The fuzz package has been created, which will house C based helper code and sub-packages dedicated to each fuzz test. A sub packaged called
fuzzParseLevelPrefix has been created to house the fuzz test for parseLevelPrefix. Emeric's C code has been isolated into some C files, and a file
called fuzz.go has been created, which houses the actual fuzz test function. An initial corpus has been added with 3 inputs.

The functions firstly derive the value of nC and then read the value of coeff_token from the BitReader. The table read prior and loaded into
a 'map' is then used to get the corresponding values of TrailingOnes and TotalCoef.
