codec/mjpeg: tidying up
...
Separated my code from code that was ported from ffmpeg (differen copyright). Also added utils.go file to house the putBuffer and bytestream types. Reduced copying and use of bytes.Buffer.
Instead expanded putBuffer functionality so that I can use this throughout process (reduce copying from buffer to buffer).

codec/mjpeg/jpeg.go: added writeHeader function to write JPEG header

This also included the addition of some lunimance and chrominance tables, a multiError type (implements error) and a putter type, that will put uint16s, bytes and "buffers" into a byte
slice.

alsa: unexported ringbuffer chunksize
...
Chunksize can be calculated without needing an ALSA device instance.
Added a DataSize function to pcm package for calculating size of pcm data given relevant attributes.
Removed ChunkSize from config revid config struct.
Changed NewByteLexer to accept an in rather than a pointer.

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.
