           Summary: [basesrc] allow dynamic value of the seekable value.

Now in basesrc the is_seekable function from the baseclass is only called once
at start. So this means that baseclass can choose only at startup that it would
be seekable or not.

If you want to create an element that can enable/disable seeking, like a dvd
src that isn't seekable in the menu's but is seekable in the movie, it is not
possible to inform the baseclass about it with the current implementation.

This patch ask on every query on the baseclass if it is seekable. So, it is now
possible for the baseclass to disable/enable seeking.
