ada06502b5 gstreamer: Remove redundant stream/stream collection property getters

a884a419db gstreamer/buffer: Add a BufferCursor / BufferCursorRef helper structs 
This implements Read/Seek or Write/Seek and allows to read/write/seek
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

b21f576430 Add #[must_use] attribute to mutex guards / stream lock

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.

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`).

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/issues/215

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.
