Revive message in dispose handler before we signal the bus thread,
otherwise the bus thread might be woken up and unref the message
before we had a chance to revive it yet.
Async message delivery (where the posting thread gets blocked
until the message has been processed and/or freed) was pretty
much completely broken.
For one, don't use GMutex implementation details to check
whether a mutex has been initialized or not, esp. not
implementation details that don't hold true any more with
newer GLib versions where atomic ops and futexes are used
(spotted by Josep Torras). This led to async message
delivery no longer blocking with newer GLib versions on
Linux.
Secondly, after async delivery don't free mutex/GCond
embedded inside the just-freed message structure.
Use a new (private) mini object flag to signal GstMessage
that the message being freed is part of an async delivery
on the bus so that the dispose handler can keep the message
alive and the bus can free it once it's done cleaning up
stuff.
If an element implements wrongly the URI query and set the uri to NULL and if
the element calls gst_pad_create_stream_id at some point, it will lead to crash
as the uri is not supposed to be NULL in the gst_pad_create_stream_id_internal
function.

Before we just took the values from the first pad that succeded the query,
now we accumulate the results of every sinkpad properly and return that
result.
These docs missed many details that were not obvious and because of that
handled in a few different, incompatible ways in different elements and base
classes.

Add a hold off when the clock calibration suddenly loses synch,
as it may be a glitch, but also make sure we update if it stays
desynched for more than a few seconds
Add GST_SEEK_FLAG_TRICKMODE_KEY_UNITS and
GST_SEEK_FLAG_TRICKMODE_NO_AUDIO, and rename GST_SEEK_FLAG_SKIP
to GST_SEEK_FLAG_TRICKMODE (with backwards compat define).
Do the same for the corresponding SEGMENT flags.

Make host IPs in square brackets store only the IP, i.e. strip the brackets.
Strip leading whitespace characters in URIs.
Fail parsing when host part does not match any valid formats from RFC3986.

The problem was that the macro was always used with 'ret' as the defaultval
argument.
This would result in the macro eventually expanding to
if (G_UNLIKELY (ret != ret && ret != GST_FLOW_OK))
... ret != ret will always fail, and therefore we'd never call the
following line.
Instead of that, store the previous value locally for comparision
Add the minimum-update-interval property to the clock, with a default
of 50ms and don't send polling requests faster than that. That helps to
ensure we spread the initial observations out a little - startup takes
a little longer, but tracking is more stable.
Move the discont skew limiting code inside an if statement, so that
it's only done when the linear regression succeeds and the clock
parameters might actually change.
Add domain checks for the input values, and a variable precision
calculation that loops if necessary to ensure we never overflow
accumulators and then silently produce garbage results.
Make the (non-public) linear regression function available for
unit testing by putting it in a separate source file the test
can include. Add a unit test that the new regression function
produces sensible results for several inputs taken from real-world
captures.
Allow setting a GstBus on the network clock client
via a new 'bus' object property. If a bus is set, the
clock will output an element message containing statistics
about new clock observations and the clock correlation.
When the local clock is synchronised with the remote, limit the
maximum jump in the clock at any point to be one average RTT to
the server. Also, publish in the bus message whether we are
synched with the remote or not.
gst_clock_add_observation_unapplied() adds a new master/slave clock
observation and runs the regression without activating the new
calibration results.
