There are many good use cases for GstIndex and we want
to add it back again in some form, but possibly not with
the current API, which is very powerful (maybe too powerful),
but also a bit confusing. At the very least we'd need to
make the API bindings-friendly.
Move the flag to indicate that a new_base_time should be distributed to the
pipeline, from the async_start to the async_done message. This would allow us to
decide when to reset the pipeline time based on other reasons than the
FLUSH_START event.
The main goal eventually is to make the FLUSH events not reset time at all but
reset the time based on the first buffer or segment that prerolls the pipeline
again.
This reverts commit cf4fbc005c.
This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.
API: GstElement::state_changed
This is always called when the state of an element has changed and
before the corresponding state-changed message is posted on the bus.
The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.
Fixes#396774.

Use gst_element_class_set_details_simple() instead. If you want to
convert automatically, here's a script:

Add a start_time field and some methods. The start_time will contain the
running_time of when the element last went to paused. This time can be user to
report the position in PAUSED but also to do more correct clipping and
stepping later.
Add a gst_element_lost_state_full() with an extra argument to control
distribution of a new base_time. We will need this for flushing step
operations.

Deprecated gst_element_get_pad() as it can't be used sanely. It's not
clear of the reference to the resulting pad must be released later
or not, resulting in possible leaks. Fixes bug #533865.
