Sebastian Dröge 8b9862052b gstreamer: memory: Simplify and correct offset/size calculations in mem_share() 
This is all supposed to do unsigned wrapping arithmetic to calculate the
new offsets and sizes, despite input parameters being signed integers.

Sebastian Dröge ceed45cfd7 gstreamer: Optimize Buffer / Memory from_slice() to have fewer allocations 
Instead of using `gst_memory_new_wrapped_full()` and boxing the data,
create an GstAllocator subclass that allows allocating memories that
store the data inline.

By avoiding the box, one additional heap allocation per memory is
avoided.
