a342d14ba9 ges: Add support for sources reverse playback
It introduces a `reverse` property at the `nlesource` level which will
basically reverse playback of the clip.

We guarantee that outside that clip, the data flow looks like it was
playing forward as we add an 'identity' element with `single-segment=true`.

This start making use of the newly introduced concept of
`CHILD_PROP_FLAG_SET_ON_ALL_INSTANCES` as it is natural that
doing `source_clip.set_child_property("reverse", True)` will make
the whole clip go reverse, meaning that all the GESSource children
properties will be set. To set an individual source "reverse" child
property as the desired effect.

e728c0e71a ges-source: make sure internal decodebin doesn't get seeked too early
When uridecodebin exposes pads for its streams, we immediately ghost
the relevant (selected) one and let composition send a seek as soon as a
buffer is probed.

This means that sometimes uridecodebin is still linking elements
internally (for non-selected streams) and sees flush events travel down
the elements it is still busy trying to link / forward sticky events to.

This causes all sorts of nasty issues, which can be avoided by simply
blocking all data flow from the source until no-more-pads has been
emitted by uridecodebin (or whatever sub_element is wrapped).

2fd2af9420 ges-source: do not emit no-more-pads on child element
This most likely never caused any issues as we don't connect to
no-more-pads in the first place, and the element isn't directly exposed
to the user, but emitting it makes no sense, and we are actually going
to connect to no-more-pads in a subsequent commit.

The call was added in 86b893e54c, a patch
by me in 2013, I have no idea why but I probably didn't have a firm
grasp on what I was doing then.
