This allows to only create the socketpair when it is really required instead
of always creating it and immediately destroying it again for child buses.

Especially drop tag events when flushing to not send them over
and over again.
Should've been in the last commit already but I forgot to call
git rebase --continue...
This is used by GstBin to create a child bus without
a socketpair because child buses will always work
synchronous. Otherwise too many sockets could be
created and the limit of file descriptors for the
process could be reached.
Fixes bug #646624.
Currently fails (in normal circumstances) because we create a
socket pair for each bin's bus and exhaust the number of available
file descriptors.

if set->control_pending is set to 0 but we didn't not succed reading
the control socket, future calls to gst_poll_wait() will be awaiken
by the control socket which will not be released properly because
set->control_pending is already 0, causing an infinite loop.
This caused "re-declaration" problems.

Some applications are requesting the same pad name multiple times
and the behaviour is undefined and different from element to element
but we don't want to break applications that work just fine.
In 0.11 this check should be an assertion again, although elements
have to do manual checking if the pad already exists again because
it can't be done in a threadsafe way here.
Use the string provided by the caller for the sinkpad name
if possible. Note that all sanity checking for this name
is already done in GstElement.
Fixes Bug #645931
basesrc's default event handler returns TRUE regardless of whether the
event is handled or not. This fixes the handler to conform with the
expected behaviour (which is to only return TRUE when the event has
actually benn handled). gst_bin_do_latency_func() depended on this
(incorrect) behaviour, and is now modified as well.
(Remaining 1-liner change in gstbasesrc.c is to keep gst-indent happy)
