Use multifdsink for pipes instead of multisocketsink,
to avoid "creating GSocket from fd 9: Socket operation
on non-socket "criticals from Gio. Test still fails,
but it fails in a different way now.
Fix copy'n'paste bug which made us allocate a slice of the
size of a rectangle for the overlay composition, but then
free it passing the size of an overlay composition, which
is not something GSlice takes to kindly, resulting in scary
aborts like:
***MEMORY-ERROR***: GSlice: assertion failed: sinfo->n_allocated > 0
Also, g_slice_new already includes a cast, so remove our
own casts, without which the compiler would probably have
told us about this ages ago.

The decoder might have been de-activated in the meantime (resulting
in NULL pad caps).
If the decoder really isn't configured, then it will error out further
down when checking whether the GST_AUDIO_INFO_IS_VALID()
https://bugzilla.gnome.org/show_bug.cgi?id=667562
A caps event is also used to establish that a stream has prerolled.
Without this, we end up allowing negotiation queries to fail, ending
in decoders (and other elements) to not be configured right from the
start with the most optimal settings.
Add support RTP buffers with multiple memory blocks. We allow one block for the
header, one for the extension data, N for data and one memory block for the
padding.
Remove the validate function, we validate now when we map because we need to
parse things in order to map multiple memory blocks.
Since we now use videoconvert, which supports these.
Unfortunately videoscale still crashes with 64-bit formats
right now because of a too small temp buffer, but I'm sure
someone is going to fix this real soon now, just like the
other unit tests.
Add a method to get the offset and scale values to transform the color values of
a format to their normalized [0.0 .. 1.0] range. This is usually required as
the first step of a colorspace conversion.
Add an unpack option to specify what to do with the least significant bits of
the destination when the source format has less bits than the destination. By
default we will now copy the most significant bits of the source into the least
significant bits of the destination so that the full color range is represented.
Add an option to leave the extra destination bits 0, which may be faster and
could be compensated for in the element algorithm.
