We use the segment format to detect if we run the streaming thread or not.
Without resetting we might believe we do so, although we only did in the past
and are now running in e.g. push mode.

It might still be waiting for a query to be handled, or the queue to become
empty again for the next item. Also if downstream returns FLUSHING, flush the
queue like we do in queue and multiqueue.
Otherwise we might wait forever for serialized queries to be handled as the
loop function is stopped and as such we will never ever dequeue the query and
handle it.

... and only unblock when either a) the pad becomes active and the event
should be forwarded or b) the active pad went EOS itself.
Otherwise it can happen that we switch from a longer track that is not EOS yet
to a shorter track that already is EOS, but the shorter track won't have any
possibility to send its EOS event downstream anymore.

TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.
Also normalize booleans in a few places.
Write out multiple buffers possibly containing multiple
memories with one writev() call, without merging the
buffer memories first, like ::render() does currently.
When comparing percentage values, compare with 0-100 scale as it
has already been made relative to 0-high_percent, otherwise we mark
the queue as not buffering and report a 50% to the user. This leads to
a buffering stall as the user assumes the queue is still buffering but
it thinks it isn't.

multiqueue's queues stored percent value is the percentage from 0
to 100 (max-size-*) and should be compared with the requested limit
(high_percentage) set by the user and not with 100% to check if
buffering should stop. Otherwise we are only stopping buffering when the
queue gets completely full.
In this mode we accept previously set filter caps until
upstream renegotiates to something that is compatible
to the current filter caps.
This allows dynamic caps changes in the pipeline even
if there is a queue between any conversion element
and the capsfilter. Without this we would get not-negotiated
errors if timing is bad.

If we are pushing a serialized query into a queue and the queue is
filled, we will end in a deadlock. We need to release the lock before
pushing and acquire it again afterward.

Revert the previous commit which removes the pattern property of fakesrc because
doing so will break ABI. Bringing the property back but marking it as unused
in the property string.
https://bugzilla.gnome.org/show_bug.cgi?id=737683
Eventhough the "pattern" property of fakesrc can be set, it is never used. The
only pattern supported is the default 0x00 -> 0xff, and if a pattern is set by
the user it is ignored. Removing the unused property and variable.
