6e633cbe33 basesink: update segment start/stop for clipping 
When we start stepping, store the start/stop values of the segment before we
install new start/stop values for clipping in non-flushing steps.

for non-flushing steps, update the element start time. For flushing steps, it
does not change because running_time does not advance

Make sure we always perform the stop_stepping operations even when we drop
frames.

72e8d9909c basesink: do proper clipping in stepping 
Update the stop position of the segment so that we clip correctly.
After clipping in non-flushing mode, rerender the remainder of the buffer.

89c42f8506 stepping: do flushing steps correctly 
Note in the docs that a flushing step in PLAYING brings the pipeline to the lost
state and skips the data before prerolling again.

Implement the flushing step correctly by invalidating the current step
operation, which would activate the new step operation.

c74c3bf1b3 adapter: fix _masked_scan_uint32() at boundaries 
gst_adapter_masked_scan_uint32 could return values smaller than offset
if the first byte(s) of the mask are 0 and the pattern matches the
beginning of the adapter.
Added examples to documentation of gst_adapter_masked_scan_uint32().
Also added some more masked boundary tests.
