bb77f41abf systemclock: Reorganize defined checks for parts of GstSystemClock
The gst_system_clock_get_internal_time and
gst_system_clock_get_resolution functions had some nested defined checks
making this code somewhat harder to reason about and much harder to
change. The logical meaning of the checks has changed but the actual
code coming out of the pre-processor should not have changed
significantly. The main logical change was flattening the checks for
existence of posix timing functionality, from what I can tell these
functions aren't available on Windows where they were trying to be
included. I have checked the Linux and macOS output and they are
functionally unchanged.

caa608e5c0 docs: random: clean up outdated documents
Most of these are only of historical interest, and for that it's
fine if they're maintained in the git history. They're confusing
for anyone stumbling across them expecting documentation relating

2a710a484c concat: adjust running time offsets on events
When concat adjusts the base of the segments it forwards
downstream, it needs to also adjust the running time offsets,
as GstPad does when an offset is set by the application on a pad.

1a8dfdfc54 Introduce gst_element_request_pad_simple
The name `gst_element_get_request_pad()` is confusing to people
learning GStreamer. `gst_element_request_pad_simple()` aims at
providing the exact same functionality, while making it more
explicit it is a simplified `gst_element_request_pad()`.

`gst_element_request_pad_simple()` is consistent with other
functions such as `gst_element_seek_simple`.

This commit deprecates `gst_element_get_request_pad()` so that a
compilation warning is emitted when used and incite developers
to use the more explicit `gst_element_request_pad_simple()`.

fad603011d pad: clear probes holding mutex
Protect clearing probes against concurrent modification which might happen
due to dispose does NOT guarantee that the object is not used anymore, as
it could be referenced again and so being continued used.
So, as in the rest of places where probes hook list is used, on dispose
it should be accessed holding the mutex "GST_OBJECT_LOCK (pad);" as
GHookList is not thread-safe.

4eef67cc7e queue2: Refuse all serialized queries when posting buffering messages
When posting buffering messages there are no safe places or timing to avoid
deadlocks.

Previously the code was trying to be "smart" by only forwarding serialized
queries if the queue was empty ... but that could happen when queue2 hadn't yet
posted a 100% buffering message. Meaning the pipeline might be paused and
pushing a serialized query downstream might never complete.

Therefore let's completely disable forwarding of serialized queries when
`queue2` is used as a buffering element (meaning `ALLOCATION` and `DRAIN`
queries).

defe732ae0 aggregator: Release pads' peeked buffer when removing the pad or finalizing it
The peeked buffer was always reset after calling ::aggregate() but under
no other circumstances. If a pad was removed after peeking and before
::aggregate() returned then the peeked buffer would be leaked.

This can easily happen if pads are removed from the aggregator from a
pad probe downstream of the source pad but still in the source pad's
streaming thread.

12661d90a3 value: fix parsing of explicit value casts
Since acdb4ce03d , parsing of the
value for a property can use the pspec to determine what type
a value should be casted to.

However, this broke the case where the value is explicitly casted
to a type (eg <(float) 0.0>). In that situation, we want to respect
the casting decision, and only use the pspec to perform "implicit"
casts.
