When importing the prelude of a crate like `gst` the `glib` prelude is
provided too. Shedding these imports saves quite a few lines and
adheres to keeping it simple; we're not reexporting base/parent preludes
for no reason :)
For cleanliness the prelude module only needs to reexport preludes from
direct, "top-most" crates, which themselves take care of reexporting
preludes from its dependencies again. This shaves off some code while
maintaining the same set of exports.
In gir it was brought up [1] that some traits (in particular
`*ExtManual`) are exported from the crate root in addition to the
prelude, cluttering the environment unnecessarily. This commit removes
all these reexports, leaving those in prelude (that were already there)
only.
After this commit everything matching `Ext(Manual)?\b` in `lib.rs` sits
within `pub mod prelude {};`.

The `lgpl-docs` and documentation embedding step is now solely invoked
from `./gir/generator.py` in the CI, and does not need the embed/purge
build features anymore.
The `lgpl-docs` crate and all precompiled (easy to get outdated!)
docmentation files are removed in favour of being generated at runtime
by the improved generator, both during local development as well as in
the CI.
The previous commit reinstantiated `girs_dir`, and this commit applies
the rename to `girs_directories` and adds the new/missing
`gst-gir-files` directory where GStreamer-specific `.gir` files live.
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.
Gir now prints all directories and their hashes in the version file and
comments; useful now that gstreamer-rs is being generated from both
gir-files/ and gst-gir-files/ submodules.
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.
The sys crates have not been generated with 1.20 introspected gir files
yet, and break the documentation that is already compiling with the
v1_20 feature. Function body contents don't truly matter for the
documentation build anyway.
This scales better as there will only be only such data instead of two
or more when having deeper class hierarchies with multiple Rust
elements, and also makes it unnecessary to use a special instance struct
so the default works well.
This should be analogous to C struct initalizers where all unspecified
fields are initialized to zero. Without mut this reads a bit nicer as
well.
Note that two out of three structs have all members specified, hence
need no zero-initialization of the remainder at all.
As ffi::GstVideoTimeCode implements Copy, assignments don't move it out
of the passed in value but just copy it. This doesn't increase the
reference count of the daily jam, still runs the Drop impl of the passed
in value to decrease the daily jam and then causes a second unref of it
later when the returned value is dropped.
Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/issues/310
gir has been fixed to omit all unnecessary imports from objects, enums
and flags which currently are the only offenders of this linter warning.
Hence disallow this warning from now on which is anyway not applied to
every crate - like gstreamer-gl - where such issues have been uncovered.
