Handle race condition between ABOR answer and other answer when stopping the FTP data connection. Patch by Andrew Zaikin with cosmetic changes.

  not all video. enables to restream/transcode rtsp/h264 streams.
  Should also partly fix #397, it seems that most of h264 streams are
  with packetization-mode=1 eg. in decoding order (thou it should be
  checked here, and FIXME is for that).

- only start GET_PARAMETER keepalive-thread if x-asf is setted eg. when
  server is wms, DSS 5.5.4 & 5.5.5 doesn't like GET_PARAMETER at all and
  closes the connection when getting that, and they seem to use
  rtcp-data for liveness. Kasenna uses that KA in useragent-string.

Marq: make it possible to mix (x,y) and position options. Example: "marq{marquee=Test,position=1,x=100}" will put the text 100 pixels from the center of the left border. Also add deprecated elements for the old time module options.

control/media_instance.c: Make sure media_instance_pause() will either, play, pause, or stop, depending on the whether the input can be paused or is playing.

control/media_instance.c: Make sure the toggling the of the pause status implies a right "state" callback.
