c811d51471 basesink: forget previous times when stepping 
When we start a flushing step operation, forget about the previous stream time
so that the position reporting works correctly.

71a5ebe638 basesink: fix regression in unit tests 
Store the timestamp of the buffer after prerolling. While we are prerolled we
want to report the position of the segment start value.

484d188440 basesink: post a warning on excessive framedrops

this fact.

8c54c70d9c basesink: use start_time as the step start 
Use the start_time of the element as the point from where the step operation
starts. This fixes stepping in all paused states.

642bb32196 basesink: catch step cases in _wait_preroll() 
When a subclass is blocking in _wait_preroll() in the _render method, make sure
we can unlock the subclass and detect this return value from the render method.

0c205b96b4 framestep: implement backwards framestep 
Update framestep document, we want to pass the flush flag in the step-done
message.

Add flush flag to the gstmessage.

Update examples to use the new step-done message api.

Implement framestep with playback rates < 0.0 too.

f07b86f18b basesink: move stuff around, more stepping 
Make start and stop_stepping methods and move their invocation in the right
places.

Perform the atual stepping operation where we have full context about the
timestamps.

546c959f26 basesink: first stab at frame stepping in PAUSED 
Unlock the prerolled frame and recheck if we need to step.
Keep a simple counter for the frames we're about to skip while stepping and
preroll/post step_done when stepping finished.

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.
Fixes #584118

270723c85c adapter: add _masked_scan_uint32 
Add a reasonably optimized new gst_adapter_masked_scan_uint32() function
to scan the adapter for a pattern after applying a mask.

Add some unit tests.

13f8041238 basesink: fix once-per-second 'emergency rendering' for case where all buffers but the very first are late 
Due to a typo basesink didn't do any emergency rendering of late buffers
if the only buffer ever rendered was the first one with timestamp 0. This
means that in cases where the decoder is very very slow, we'd never see
any buffers but the very first one rendered. Fixes #576381.

805569c873 Don't forward LATENCY event when not ready

also don't try to forward the latency event because that might cause unexpected
errors when upstream is not yet linked.
