           Summary: audioresample does invalid writes

Originally from bug #310380, Thomas says:

I ported audioresample, it uses basetransform now as well.

Some conversions make it unhappy though.

This one shows an invalid write:

 /home/thomas/gst/head/gstreamer/tools/.libs/lt-gst-launch-0.9 -v sinesrc
num-buffers=2 ! audioresample ! audio/x-raw-int,rate=16000 ! fakesink


This one throws an error, because resample writes more bytes than it was told to
(grep for "bastard" in the log), which also causes an invalid write.

/home/thomas/gst/head/gstreamer/tools/.libs/lt-gst-launch-0.9 -v sinesrc
num-buffers=2 ! audio/x-raw-int,rate=44100 ! audioresample !
audio/x-raw-int,rate=8000 ! fakesink

There are also cases where resample writes less bytes than it reported it was
going to.  The previous pipeline will probably do that for the first buffer, and
then error out on too many bytes on the second.
