Saxon 90ab359599 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).

Saxon ba25cdfd12 codec/mjpeg/extract.go: wrote Extractor type
Wrote extractor type that provides an Extract function to extract JPEG frames from an RTP/MJPEG stream and writes them to a destination.

Saxon c2ce700cbd 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.

Trek H cd63d0d95a 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.

Trek H 5e472ba4c9 pcm: refactored to be general not alsa only
Addition of new structs and helper functions for passing around pcm clips/buffers and their formats so that we don't have to import and rely on yobert/alsa code.

Updated any commands and alsa package to use refactored code.

Saxon 38cfad7b67 revid: fixing some more bugs
Fixed H264 RTP extractor. Fine tuned some timing regarding geovision setup. Added some more
logging to geovision setup.

Saxon f336a03d7a 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.

codec/mjpeg/lex.go: returning nil error from Lex if we get io.EOF on reading bytes

Saxon fc4e88bce6 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.
