ea3d0246bf gstreamer/log: Fix debug_remove_default_log_function() to actually work 
We have to pass `NULL` / `None` instead of the actual default log
function as because of `-Bsymbolic` or how DLLs work on Windows the
external function pointer is different to the internal one.

43d1d0a4e9 gstreamer/pad: Factor out PadProbeInfo handling from pad probe trampoline into separate functions 
This makes that part of the code non-generic and thus allows the
compiler to not put a copy of it into every caller with a different
closure.

For a test with 3 pad probes this overall reduced the number of LLVM IR
lines needed for the pad probes to about 8.5% of what it was before
(4485 -> 381 lines).

3adc3d9337 functions: Add new parse_bin_from_description_with_name utility 
This is basically `parse_bin_from_description()` but additionally the returned
bin has the passed name. It is sometimes convenient to name those bins so they
can later be easily retrieved by name from the pipeline they belong to.

7086a754be Add various glib::Value trait impls for borrowed versions of types 
For SDPMessageRef, StructureRef and CapsFeatureRef this involves the
conversion from and to a glib::Value. Specifically this means that e.g.
a StructureRef can be retrieved from a glib::Value via borrowing, i.e.
without creating a copy of the structure first.

For all mini objects only retrieval from a glib::Value is implemented as
the other direction would allow to get multiple immutable references
from a mutable reference without borrowing, which is not allowed and
would make it possible to observe a mini object changing while having an
immutable reference to it.

93bc5c9324 gstreamer/gstreamer-app: Don't store strong references in futures Stream/Sink adapters 
This applies to the ones of the appsink, appsrc and bus. If we would
store a strong reference then they would keep alive the underlying
object forever even if their pipeline disappeared in the meantime.

Like this e.g. the bus stream would start returning None once the bus
was destroyed, similar to how other channels are working in Rust.

into the buffer without merging the memories inside.

The writer also only maps the memory write-only as compared to all other
ways of accessing the buffer/memory data in a writable way, which have
to map it read-write.

See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/425
for a similar API proposal for GStreamer core.

d58cf01e3a Allow changing bus sync handler and appsink/src callbacks when running with 1.16.3 or newer 
Previously it was not thread-safe to change them and could lead to
crashes but with 1.16.3 it is now.

Unsetting the bus sync handler before 1.16.3 will have no effect at all,
setting a new bus sync handler or appsink/src callbacks will panic.

This partially reverts 2f88dc6576

fe4f074e90 bus: Don't use the bus sync handler in the bus Stream to notify about messages being available 
This is racy and can cause the consumer of the messages to never be
woken up anymore:

1. Waker is stored because no message on the bus
2. Sync handler is called, waker is woken up
3. Bus is polled again and no message is on it (yet),
   new waker is registered
4. Bus stores the message from 2. in its queue (after
   the sync handler has returned BusSyncReply::Pass)
5. No new message ever appears on the bus because all
   this happened for the very last message

63a8afafa5 gstreamer: Use more accurate types for Seqnum, GroupId and MetaSeqnum 
For the latter introduce an actual opaque type that allows using them
for comparison purposes but is not just a plain u64.

For the former represent them as opaque type around an NonZeroU32. 0 is
the invalid case and does not happen in the majority of functions. Where
it can happen, represent this case by using an Option<_> instead.

This makes it harder to mis-use these types.
