From Alexander Prokoudine
Generalize no-plugin-state from AudioUnits to all plugins

Replace AU_STATE_SUPPORT compile-time define with NO_PLUGIN_STATE and make it prevent plugin state setting, preset loading, preset saving and plugin state saving. Blocks on these actions exist partially in the backend and partially in the GUI (this latter class are not absolute, and should OSC or MIDI be able to drive Plugin::save_preset() the block could be circumvented). Set NO_PLUGIN_STATE if --freebie is used at waf-configure time
avoid name-conflict

when compiled with -rdynamic, "AudioStream" symbol
conflicts with AspectVST.so
NOOP clean up code

move curl-http-get wrapper-function which is used by various
videotimeline related code to util.c

vtl: update ffmpeg option sameq/qscale
vtl: use avi/mjpeg (insted of mpeg4) for video proxy

 * average picture quality is worse
 * ..but seeking works accurately
   (no more PTS/DTS mess with Quicktime files)
 * ffmpeg transcode to mpeg4 retains PTS, DTS ( to mjpeg does not)
 * eventually harvid&xjadeo need to be
   updated to seek to non-monotonic PTS, DTS timestamps
remove executable mode-bit from files
vtl: remember original video-file for later export/mux
