Fix a memleak in gst_cmml_track_list_add_clip.
Handle overflows in clip's start and end times.
Add the "encoded" parameter to cmmldec and cmmlenc caps.
Do not parse junk at the end of a CMML preamble buffer.
Register a libxml error handler to not print stuff on stderr.
Check for bad clip start and end times in the testsuites.
