Avoiding to be in an inconsistent state where we do not have
actual negotiate caps set as srccaps and leading to point where we
try to unref ->srccaps when they have already been set to NULL.

Along with the required mandatory dependent events.
Some elements need to perform an allocation query inside
::negotiated_caps(). Without the caps event being sent prior,
downstream elements will be unable to answer and will return
an error.

When registering categories after gst_init() we would re-check *all*
categories against the existing GST_DEBUG patterns again, whereas
it's enough to just check the new category. Moreover, we would parse
the GST_DEBUG pattern string again and re-add that to the existing
pattern list for every newly-registered debug category, and then
check that against all categories of course. This made registering
categories after gst_init() very very slow.
When registering a new debug category after gst_init(), simply check
the existing patterns against that new category.
No need to iterate over all categories and recheck them all against
the existing patterns.
Also, no need to re-parse the existing pattern string set via GST_DEBUG
and add the same set of match patterns all over again to the existing
list of match patterns every time we register a new debug category.
Combined with iterating all debug categories on a change this would
make adding debug categories after gst_init() very very very slow.
The gst_ptp_clock_new() does not actually require a name. However, for
example the rtpjitterbuffer may create a clock without a name, fail, and
fall back to not using the PTP clock.

The check for dropping precision was wrong when sxx and syy were negative.
if they are negative then "G_MAXINT64 - val" would always overflow
The check was meant to use G_MININT64 (like in the loop contained just
after).
Fixes in user code:
undefined reference to `gst_harness_add_element_sink_pad'
Also reorder harness function list to be strictly in alphabetical order and
double check the list with:
awk '{ if ($1 !~ /#define/) if ($2 ~ /gst_harness_/) { print $2 }; if ($3 ~ /gst_harness_/) { print $3} }' libs/gst/check/gstharness.h | sort
`./configure --disable-gst-tracer-hooks` didn't do anything, hooks were
always enabled regardless of the option. It works correctly in the
Meson build though.
Checking that the pad is in the correct mode before the parent is
checked makes the call always succeed if the mode is ok.
This fixes a race with ghostpad where gst_pad_activate_mode() could
trigger a g_critical() if the ghostpad is unparented while the
proxypad is deactivating, for instance if the ghostpad is released.
More specifically, gst_ghost_pad_internal_activate_push_default()'s
call to gst_pad_activate_mode() would fail if ghostpad doesn't have a
parent. With this patch it will return true of mode is already
correct.
