Makes audio ts parser default. Suspend fixes.

New easier and more flexible audio PES packet parser, which includes own
codec parser.
Removed av_parser use.
Reduced audio buffer time, faster channel switch.
New audio transport stream parser (not enabled as default).

+    Experimental ac3 audio drift correction support.
+    Removes LPCM detection from TS parser.
+    Rewrote video/audio start code.
+    Add support for attach/detach plugin.
+    OSS needs bigger audio buffers.
+    Improved audio drift correction support.
+    Experimental audio drift correction support.
+    Add SVDRP HOTK command support.
+    Increased audio buffer time for PES packets.
+    Support configuration and set of video background.
+    Survive lost X11 display.
+    Fix bug: 100% cpu use with plugins like mp3.
