Use the technique that is now done in GTK+ so that the plugins do not have
to be installed in c:\gstreamer\lib\<debug>\gstreamer-$(GSTApiVersion),
but can be installed in
<parent_folder_of_gstreamer_main_dll>\lib\<debug>\gstreamer-$(GSTApiVersion),
or as per g_win32_get_package_installation_directory_of_module() allows.

... instead of returning a reference to a global instance. The caller might
want to change the global instance otherwise, which causes funny effects like
all global instances being changed and at the same time nothing in the caps
being changed.
As the caps might be immutable while we do this we have to do some magic
with atomic operations.

Keep an extra write ref on the control socket. This ensures that we
avoid a read/write on the socket when going from non-empty->empty->not-empty.
We remove the write ref only when we actually are empty and we need to
wait for flushing or a new buffer.
This makes the bufferpool benchmark about 30% faster than the pure
malloc implementation.
This way we make sure that a) the lock is always taken when checking
the cookie and calling the iterator's next functions and b) it is
not taken while calling any of the iterator filter functions.

events_foreach adds an extra ref when giving the event to the
user function. In case it was unrefed by the user, this extra ref
disappeared, but events_foreach still should unref again to
lose its own ref before removing the event from the array.

Make this work again:
audiotestsrc ! tee name=t t.src_0 ! queue ! fakesink t.src_1 ! queue ! fakesink
and this fail again:
audiotestsrc ! tee name=t t.src_1 ! queue ! fakesink t.src_0 ! queue ! fakesink
as tee just counts itself and does not care about the pad names we request
from it.
This allows blocking a pad, add a new blocking probe, removing
the first probe and then having the second probe called. Which
could then decide that data-flow should actually continue
instead of blocking now.

Also only check the data types for non-IDLE probes. When we
are idle, we have no data type obviously.
Previously we were calling IDLE probes during data flow whenever
a non-blocking probe would be called. The pad was usually not idle
at that time.
Checking twice the lower bound is great (you never know, it might change
between the two calls by someone using emacs butterfly-mode), but it's a bit
more useful to check the higher bound are also identical.

If a category with the same name is found when creating a new
one, the found category is returned instead of an invalid pointer.
Fixes issue with gst-vaapi (which uses an internal copy of the
codec parsers) caused by commit ccba9130.
