crates get this attribute in their own (generated) lib.rs file the safe
wrapper crates do not have such an autogenerated lib.rs file.

a7749b7933 gstreamer/log: Don't provide direct access to the logged object as glib::Object 
It might just be constructed or might be finalized currently and it's
not safe to use any APIs on it.

Instead provide a small wrapper type that allows to get the underlying
pointer and that implements the Display trait to print the name of the
object.

ae9d97dfca ClockTime & opt Formats: fix PartialOrd impl, remove Ord and add min & max 
- `PartialOrd` was returning `true` for expressions such as
  - `ClockTime::none() < ClockTime::from_seconds(1)`.
  - `ClockTime::from_seconds(1) > ClockTime::none()`.
- Remove `Ord` because `ClockTime` is not a total order due to
  `ClockTime::none()`. See test `not_ord`.

This also applies to others `Format(Option<{u32,u64}>)` types.

c987bb0c7d gstreamer/message: enhance Debug impl for Message[Ref] 
When "{:?}" printing a Message[Ref], the following issues lower the

- If the Message seqnum is GST_SEQNUM_INVALID (0), a panic occurs due
  to an assertion failure in MessageRef::get_seqnum.
- The src of the Message displays the GString address.

cb362e6fbc gstreamer: plugin: Prefix glib:: with $crate:: in gst_plugin_define 
Crates using gst_plugin_define might not (need to) import `glib`

to make this macro more portable.
Besides, `glib` is prefixed with `$crate::` just below.

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).

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.

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.

Make sure that `log_handler` and `DebugMessage::get` do not panic while
processing non-UTF8 characters by using lossy instead of strict UTF8
string conversion.

06cfcd57fc Move to_string() methods into the Display trait or rename to to_str(), move from_string() into the FromStr trait 
Fixes clippy warnings, prevents confusing errors and is more consistent.

The Display trait provides a to_string() method by itself and FromStr
provides from_str().

Iterator: Add a wrapper implementing std's Iterator 
Transposing the item type lets us be a std-compatible Iterator.

The iterator is automatically resynced when resuming iteration after
yielding Resync. This lets some combinators like `collect` and `find`
work properly.

c74eef374a Fix serde for Values with optional Types 
Attention: these changes induce breaking changes for the serde
representation of some types.

Serialization of `Value`s used to rely on the `get` function
followed by an `unwrap`. This means that optional types couldn't
be serialized when they were `None`.

This commit distinguishes between the optional `Value` `Types` and
the ones that always return some value.

The `Value`s, `Structure` fields and `Tag`s with following types are
now represented as `Option`s:

- `Buffer`
- `DateTime`
- `Sample` (note: this type is used for `Tag` images)
- `String` (except for `Tag`s - see the comment in `tags_serde.rs`).

The representations for these `Type`s remain unchanged when they are
used in-place (not as part of a `Value`).

e00781309b gstreamer/element: Use from_glib_none() for the release_pad() trampoline 
The reference to the pad we get passed is not guaranteed to be valid for
the whole scope of release_pad(). It might be the last reference as
owned by GstElement, and gst_element_remove_pad() would destroy it then.

1b860825ee Update feature flags of all dependencies to include the same version as for the crate itself 
This improves build times as it allows cargo to reuse more previous
build results when building crates separately.

Also remove the serde-pickle dependency. It was only used in a single
test and caused pulling in of quite a few dependencies.
