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.
The x/y values are meant to be signed.

When the ringbuffer gets restarted (like in setcaps), we *will* have
to resync against the new values.
Without this we end up blindly assuming the new samples align to the
old ones.

Fix the calculation of the offset and scale values for GRAY formats. We also
need to set the offset and base of the chroma values to match what the unpack
function creates.

Add a copy of the base class until it is stable. Right now the extra effects of
the baseclass are not supported as the sublass overwrites the buffer instead of
blending.
