docs/plugins/.cvsignore: Ignore *-undeclared.txt

Original commit message from CVS:
* docs/plugins/.cvsignore:
Ignore *-undeclared.txt
* ext/resindvd/rsnaudiomunge.c:
Turn g_print's into debug statements.
* ext/resindvd/resin-play:
* ext/resindvd/Makefile.am:
* ext/resindvd/resindvdbin.c:
* ext/resindvd/resindvdbin.h:
* ext/resindvd/rsnparsetter.c:
* ext/resindvd/rsnparsetter.h:
* ext/resindvd/rsnwrappedbuffer.c:
* ext/resindvd/rsnwrappedbuffer.h:
Add a bloated implementation of a really simple idea: Replace the
pixel-aspect-ratio in the output video with a prescribed one when
necessary. There must be an easier way.
Split the dvdspu out of the resindvdbin and put out the subpicture
stream on the subpicture pad.
* ext/resindvd/gstmpegdemux.c:
Send video-aspect events down the pipe from the demuxer.
* ext/resindvd/resindvdsrc.c:
* ext/resindvd/resindvdsrc.h:
Handle timed-stills somewhat using g_cond_timed_wait, with a FIXME
to make it use clock-waiting later.
* ext/resindvd/rsnbasesrc.c:
Don't overwrite the last_stop in the basesrc segment after a seamless
seek.
