[PATCH] [playbin2] collect the caps of sink elements in advance

updated the patch.
it collects the info. into a hashtable which maps the sink element's typename
to the caps in READY state. 
This is done in initialization and updated when custom-sinks are changed or
some plugins are added or removed, before those elements are created and used.
The hashtable holds the info not only on custom sinks but on auto-pluggable
sinks,
and in autoplug_continue_cb() it is used to determine the auto-plugging should
be stopped or not.
# Sinks with "ANY" caps should not be auto-pluggable, though, I think.
