468ec5bc40 bufferlist: simplify bufferlists 
We now have multiple memory blocks as part of the buffers and we can therefore
reduce the bufferlist to a simple array of buffers.

Improve the calculation of the duration. When we have no input duration set on

f83ea8233b basesink: Fix treating base_time as unsigned in position calculation 
Element base_time is a signed quantity, which leads to basesink returning
a position of 0 when dealing with a negative base time - which are quite
legal when clocks (such as the audio clock) are close to 0.

This doesn't manifest in normal pipelines, of course - but can happen
(at least) when manually setting the base time on a pipeline.
