Asking to select no streams makes no sense and can create various
issues.
If one doesn't one any stream it should deactivate (or not use) the
element in question.
Various plugins use the value of '0' as an invalid seqnum value
(qtdemux for matching duplicated seek events, for example). Make
that behaviour explicit, create a GST_SEQNUM_INVALID value,
and ensure gst_util_seqnum_next never returns it.
For linked elements, the resulting gst_bin_iterate_sorted() will
properly return elements from sink to sources.
If we have some elements that are not linked, we *still* want to
ensure that we return:
* In priority any sinks
* Last of all any sources
* And in between any element which is neither source nor sink
For this to work, when looking for the next candidate element,
not only check the degree order, but if there are two candidates
with the same degree order, prefer the non-source one.
Amongst other things, this fixes the case where we activating a
bin containing unlinked sources and other elements. Without this
we could end up activating sources (which might start adding pads
to be linked) before other (to which those new source element pads
might be linked) are not activated

There were a few errors:
* The plugin scanner now accepts executable path as an argument.
In case it is NULL, argc == 2
* We find the executable path in init_pre instead of gst_init,
allowing this to work when gst is initialized through the
option group (eg gst-inspect)
* There was a semi-colon missing in the __APPLE__ #ifdef
When a plugin declares a dependency using this flag, all the
relative paths are considered to be relative to the path of
the main executable.
We try to determine the path of the executable portably,
with implementations provided for Linux, Windows and Mac.
If retrieval of the path fails, we will not detect changes.
In order for the main executable path to be the same when
scanning a plugin in a child process, a new variable is
exposed in gst_private.h, _gst_executable_path

If multiple probes are set on a pad and one probe returns either
GST_PAD_PROBE_HANDLED or GST_PAD_PROBE_DROPPED we need to stop
calling the remaining probes.

for vararg parameters. Vararg functions are not introspectable anyway,
so might just as well mark them as '(skip)' while we're at it.
gstutils.c:2611: Warning: Gst: invalid "transfer" annotation for <varargs>: only valid for object and GVariant types
Without the former, event changes (e.g. setting a pad offset) does not
take effect for the current buffer but only for the next one. Without
the latter, non-blocking event probes would not see any updated events
yet.
This stores debug logs in memory per thread and uses up to a
configurable amount of bytes per thread for the logs. Inactive threads
are timed out after a configurable amount of time.

Add back function guard that checks the refcount in a read-only
operation first, and bail out without modifying the passed-in
memory if it's clearly not a valid mini object. Otherwise we
probably cause more harm than good. We keep the second sanity
check based on the 'real refcount' at the time of the unref
around for now too.

gst_protection_filter_systems_by_available_decryptors() takes an array
of strings and returns a new array of strings filtered by the available
decryptors for them so the ones you get are the ones that you should be
able to decrypt.

Need to pass -DGST_DISABLE_DEPRECATED to avoid warnings when
testing deprecated API such as gst_uri_construct().
Also remove #ifndef GST_DISABLE_DEPRECATED guard from header
file, we don't use those any more for functions, the
GST_DEPRECATED_FOR macro is enough.
