Adding an option to keep them no matter what.
Log files are often pretty large and keeping them around can be annoying,
usually people won't look at logs files for passing tests, and we do not
even print them out.

Only in LTC mode we introduce additional latency that is depending on only on a
property and not on the framerate, so waiting for the framerate is not necessary.
In all other modes no latency is introduced at all and the latency query can
simply be proxied.

There is no point in having an endian marker on 8 bit bayer format names since
it is just one byte. Thus remove it.
This also fixes an incompatibility with plugins bad where there is no endian
marker on 8 bit bayer format names as well.

The `reuse` property end up setting the SO_REUSEADDR socket option for
the UDP socket. This setting have surprising effects.
On Linux systems the man page (`socket(7)`) states:
```
SO_REUSEADDR
Indicates that the rules used in validating addresses supplied
in a bind(2) call should allow reuse of local addresses. For
AF_INET sockets this means that a socket may bind, except when
there is an active listening socket bound to the address.
```
But since UDP does not listen this ends up meaning that when an
ephemeral port is allocated (setting the `port` to `0`) the kernel is
free to reuse any other UDP port that has `SO_REUSEADDR` set.
Tests checking the likelyhood of port conflict when using multiple
`udpsrc` shows port conflicts starting to occur after ~100-300 udpsrc
with port allocation enabled. See issue #3411 for more details.
Changing the default value of a property is not a small thing we risk
breaking application that rely on the current default value. But since
the effects of having `reuse` default `TRUE` on can also have damaging
and hard-to-debug consequences, it might be worth to consider.
Having `SO_REUSEADDR` enabled for multicast, might have some use cases
but for unicast, with dynamic port allocation, it does not make sense.
When not using an multicast address we will disable port reuse if the
`port` property is set to 0 (=allocate) and warn the user that we did
so.

Combine the appsrc and appsink settings into one place and ensure that
the appsrc will output a TIME segment, to avoid incorrect segment format
criticals in some situations.
The D3D11 path was already setting the segment format correctly.

The gst_dep.get_variable('libexecdir') may fail in some scenarios
(e.g. building a module alone inside an uninstalled devenv) and
it shouldn't really be reached in the first place if docs are
disabled via options.
Also to avoid confusing meson messages when cross-compiling or
doing a static build.

This commit adds a Find Module implementing the necessary logic to link
against GStreamer, while implementing some extra bits to enhance the
compatibility.
The first addition is the `mobile` target, which implements the
monolithic `gstreamer_android` library, and which here gains
compatibility with Apple's operating systems.
The second addition is the handling of the basic GStreamer libraries as
`--whole-archive` when statically linked, which was ported from the
ndk-build project in Cerbero. This is not easy to do, as CMake suffers
from several issues that impede its proper usage of pkg-config:
- It cannot differentiate between system/compiler specific libraries
e.g. `-lm`, `-ldl`, but especially `-framework Cocoa`.
- It does not support `--whole-archive` natively until 3.27
- It attempts to reorder flags blindly by separating them with spaces,
thus requiring the use of `-Wl,` wrapping or (in the case of Apple
frameworks) manual framework lookup
The third addition is the port of the Fontconfig and ca-certificates
bundling logic.

The calculated position was off. I'm not sure of the exact cause;
possibly because we're in AU-aligned byte-stream mode, which means
`transform` is true.
Replacing the math that calculates the NALU positions with code more
similar to what is already in use for `idr_pos` seems to have fixed it.

We do not own any ref to queries when running them.
If we end up processing the query from the streaming thread, it means that it was
a serialized query, and the query is being waited to be processed on the sinkpad
streaming thread, thread which owns the reference.
