When we get an ASYNC_DONE message when a state change was busy, set the
pending_async_done flag so that after the state change completes, the bin can
check if all async elements are finished. Don't only do this for the bin itself
but for all elements.
This fixes some bins in bins that simulate async state changes by posting ASYNC
messages (such as sdpparse in uridecodebin/playbin2).
Bin collects segment-start messages and segent-done messages. it posts a
segment-done message to its parent, once it has received a segment-done for
each segment-start. Imho it should also send a segment-start if it receives the
first segment start and if parent is !=NULL. This is needed for bins in bins,
so that also higher order bins can group segment-starts and segment-dones.
Right now higher order bins will post a segment-done for each segment-done
received.

Original commit message from CVS:
* gst/gstbin.c: (gst_bin_element_set_state):
Take the (recursive) state lock between getting the locked state of an
element and changing the element state. This allows the application to
lock an element's state and then change its state without races.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_element_set_state):
When an element is in the locked state we still want to update the
base_time of the element.

Fix race for bins that simulate ASYNC state changes by inserting
ASYNC_START and ASYNC_DONE messages in their bus. We need to check for
pending ASYNC messages even when the bin does not have ASYNC children.
We note detect this behaviour because we will receive an ASYNC message
that is originating from the bin itself.
Fixes races with decodebin2 state changes.

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.

When adding elements, insert messages into the bus of the newly added
element and make sure the element is the source of the message. This
allows the parent bin to intercept the message and do the
right thing. It also avoids us posting ASYNC_START and CLOCK_PROVIDE
messages to the app (which is not allowed).

Get rid of iterating all the children when getting the state in the bin
because it is now always up-to-date.
Fix bug where locked elements would always return _SUCCESS even it they
returned NO_PREROLL before being locked.
Fix the order of the state_change, async-start/done messages that was
sometimes incorrect.
Mark the state_dirty field as deprecated, we don't need it anymore as we
are always up-to-date.
