Sebastian Dröge 73ab9054c4 Don't use unnecessary RefCell wrappers for FnMut callbacks
They don't add any safety as this is via unsafe code anyway and are not
needed to get mutable references in this context anyway, while adding a
bit of runtime overhead.

Marijn Suijten 2426d7ce8c Revert "sys: Link all v1_20 sys crates against library 1.19" - use 1.20
This reverts commit 8226c94110.

Now that GStreamer 1.20 is out, the v1_20 feature can and should link
directly to the stable release instead of the unstable 1.19 development
release.

Simonas Kazlauskas 782d84bede Remove the links annotations
The `links` annotation in `Cargo.toml` is intended to ensure that in the
crate graph there's at most one crate that's an implementation of
some sort concept.

This can make sense in some scenarios, most prominent of which is when
the crate defines `#[no_mangle]` symbols (e.g. by compiling a vendored C
library.) In that situation linking a binary that depends on two
versions of the library cannot work because of colliding symbol names.

There does not appear to be a similar reason to impose such a
restriction on the users of `gstreamer-sys` and similar, however. All of
these crates link to a system library, they do not define any
`#[no_mangle]` symbols nor they vendor and build C libraries as part of
their build process. All they do is linking to a system library.  Most
likely all the different versions of the bindings will link to the exact
same library too.

I haven't seen any global resources that these bindings use to ensure
soundness of the library, either.

This version adds a `--strip-docs` flag to `generator.py`, used in

multiple times).  It is also used in the CI to check that no
documentation disappears on stripping, ie. all documentation is properly
annotated with `// rustdoc-stripper-ignore-next`.

Marijn Suijten 666ea908a5 Revert "Gir.toml: Drop unused/renamed girs_dir in favour of gir -d"
This reverts commit 7f9fcb09e2.

`generator.py` is in the process of being moved to a generic place in
the `gir` repository for reuse across crates.  This means `-d` cannot be
passed for our GStreamer-specific `gst-gir-files` directory anymore, and
should be configured from `Gir.toml` instead.

Marijn Suijten 7f9fcb09e2 Gir.toml: Drop unused/renamed girs_dir in favour of gir -d
We were already using `gir -d` and especially now that our files are
separated across two directories that are relative to the directory
containing Gir.toml this only becomes cumbersome. Besides `gir` lacks
functionality to normalize the path, leading to ie.
gstreamer-gl/egl/sys/../../../gir-files in the version comment as a
result.

Sebastian Dröge 06e0555555 app: Don't statically declare that appsrc/appsink inherit from basesrc/basesink
Otherwise the API of the base classes will be directly available and can
cause confusion (e.g. gst_base_src_set_format() vs. the "format"
property).

All base class API should be considered "protected" from an application
point of view and only be called by the subclass itself.
