Shortcuts: Add move callback for buflib allocations

If we don't provide a callback to buflib_alloc(),
the buffer is always movable (to reduce fragmentation).

We were passing around buffers to multiple functions
that call yield() and might trigger buflib compaction.

-> add locking while we are working on the buffers.

Also added source code comments that explain
why we added the locking in that particular section.
