* ext/Makefile.am: Disable annodex for now until we figure out
how to make it build.
* ext/gdk_pixbuf/Makefile.am: Note for Thomas :
Add a rule to your checklist : "please try to at least build
what you are going to commit into -good, or if you are too lazy
to do that, please check that the buildbots are not crying because
of your commit."
Original commit message from CVS:
Gdkpixbuf ported from 0.8 to 0.10 by Renato Filho <renato.filho@indt.org.br>. gst_loader and gdkpixbufanimation still need port.

Ignore changing the GConf key to "". Ignore GConf key updates
that don't actually change the string.
For now, ignore the GConf key when the state is > READY, as
it breaks streaming. Sometime it will be nice to bring the
new sink online even mid-stream, by sending NEWSEGMENT info
and possibly prerolling.

the decoder everything's dandy and act on the flow return values
later on in the loop function. We don't want to mess up the internal
decoder state for non-fatal things like flushing pads etc. Other
than that, use GstSegment (segment seeks don't work yet though, but
should be easy to add), use boilerplate macros, drop the superfluous
'flacdec:' from debug messages, use gst_util_uint64_scale_int, and
lots of other things.
