ext/jp2k/gstjasperdec.*: Make pad template caps reflect the supported formats.

Original commit message from CVS:
* ext/jp2k/gstjasperdec.c: (gst_jasper_dec_init),
(gst_jasper_dec_reset), (gst_jasper_dec_negotiate),
(gst_jasper_dec_get_picture):
* ext/jp2k/gstjasperdec.h:
Make pad template caps reflect the supported formats.
Add or modify some debug statements, and slightly simplify image
passing to encoding library.
