51549bf6ba collectpads: Don't initially send an invalid DTS
Sending a possibly invalid DTS may confuse the muxers, which will
then think the DTS is going backward.

b5e4f7bd9d collectpads: Add negative DTS support
Make gst_collect_pads_clip_running_time() function also store the
signed DTS in the CollectData. This signed DTS value can be used by
muxers to properly handle streams where DTS can be negative initially.

558c0b97fc netclientclock: Make the clock a wrapper clock around an internal clock
The internal clock is only used for slaving against the remote clock, while
the user-facing GstClock can be additionally slaved to another clock if
desired. By default, if no master clock is set, this has exactly the same
behaviour as before. If a master clock is set (which was not allowed before),
the user-facing clock is reporting the remote clock as internal time and
slaves this to the master clock.

This also removes the weirdness that the internal time of the netclientclock
was always the system clock time, and not the remote clock time.

202f463170 netclientclock: Add NTPv4 support
This uses all of the netclientclock code, except for the generation and
parsing of packets. Unfortunately some code duplication was necessary
because GstNetTimePacket is public API and couldn't be extended easily
to support NTPv4 packets without breaking API/ABI.

cc15f68b6a netclientclock: Preparation for NTPv4 support
We extend our calculations to work with local send time, remote receive time,
remote send time and local receive time. For the netclientclock protocol,
remote receive and send time are assumed to be the same value.

For the results, this modified calculation makes absolutely no difference
unless the two remote times are different.

f7a7a569cd netclientclock: Filter RTTs based on the median of the last RTTs before considering them at all
This improves accuracy on wifi or similar networks, where the RTT can go very
high up for a single observation every now and then. Without filtering them
away completely, they would still still modify the average RTT, and thus all
clock estimations.

42b16c9e3c ptpclock: Use a system clock for the time observations instead of gst_util_get_timestamp()
They don't necessarily use the same underlying clocks (e.g. on Windows), or
might be configured to a different clock type (monotonic vs. real time clock).

We need the values a clean system clock returns, as those are the values used
by the internal clocks.

8d77759834 ptp: Initial implementation of a PTP clock
GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in
slave-only mode, that allows a GStreamer pipeline to synchronize
to a PTP network clock in some specific domain.

The PTP subsystem can be initialized with gst_ptp_init(), which then
starts a helper process to do the actual communication via the PTP
ports. This is required as PTP listens on ports < 1024 and thus
requires special privileges. Once this helper process is started, the
main process will synchronize to all PTP domains that are detected on
the selected interfaces.

gst_ptp_clock_new() then allows to create a GstClock that provides the
PTP time from a master clock inside a specific PTP domain. This clock
will only return valid timestamps once the timestamps in the PTP domain
are known. To check this, the GstPtpClock::internal-clock property and
the related notify::clock signal can be used. Once the internal clock
is not NULL, the PTP domain's time is known. Alternatively you can wait
for this with gst_ptp_clock_wait_ready().

To gather statistics about the PTP clock synchronization,
gst_ptp_statistics_callback_add() can be used. This gives the
application the possibility to collect all kinds of statistics
from the clock synchronization.

d71f5c7d73 net: keep GCancellable fd around instead of re-creating it constantly
Just create the cancellable fd once and keep it around instead
of creating/closing it for every single packet. Since we spend
most time waiting for packets, an fd is alloced and in use pretty
much all the time anyway.

4f79c5e8da basesink: Fix QoS/lateness checking if subclass implements prepare/prepare_list vfuncs
In basesink functions gst_base_sink_chain_unlocked(), below code is used to
checking if buffer is late before doing prepare call to save some effort:
    if (syncable && do_sync)
      late =
          gst_base_sink_is_too_late (basesink, obj, rstart, rstop,
          GST_CLOCK_EARLY, 0, FALSE);

    if (G_UNLIKELY (late))
      goto dropped;

But this code has problem, it should calculate jitter based on current media
clock, rather than just passing 0. I found it will drop all the frames when
rewind in slow speed, such as -2X.
