This file doesn’t contain any real implementation, it just call the
`impl` functions from the platform-specific files
`gcontenttype-{fdo,osx,win32}.[cm]`.
It serves as a location for the doc comments, introspection annotations
and API preconditions, and will be built on every platform. In
particular, this means that we get consistent GIR output for the
`g_content_type_*()` APIs regardless of whether GLib was built on Linux or
Windows or macOS.

This reflects its status as actually platform-dependent: it’s only built
on systems using the freedesktop.org content type system.
It makes the file naming match up with other platform-specific
implementations, such as `gcontenttype-win32.c` and
`gcontenttype-osx.m`.
A subsequent commit will introduce a platform-independent high level API
wrapper so that the introspection annotations from this file can be
reused between platforms.

Previously, some of the doc comments for platform-independent APIs were
in `gdesktopappinfo.c`, which is only built on Unix systems. This meant
the introspection annotations for those APIs were not used on non-Unix
systems, which caused platform differences in `Gio-2.0.gir`.
So, move those doc comments to `gappinfo.c` and put them next to some
new platform-independent wrapper functions which provide a consistent
entry point and location for the API preconditions.

On g_cancellable_cancel() we were increasing the GCancellable ref count
before emitting the ::cancelled signal, this is a safe thing to do but
it was happening while the cancellable was locked, and this may have
potentially waken up some toggle notifications.
To prevent this, reference the GCancellable just before locking.
GCancellable is meant to be used in multi-thread operations but all the
cancellable instances were sharing a single mutex to synchronize them
which can be less optimal when many instances are in place.
Especially when we're doing a lock/unlock dances that may leave another
thread to take the control of a critical section in an unexpected way.
This in fact was leading to some races in GCancellableSources causing
leaks because we were assuming that the "cancelled" callback was always
called before our dispose implementation.
As per this, use per-instance mutexes.
The lock is also now used only to protect the calls that may interact
with cancelled state or that depends on that, as per this we can just
reduce it to the cancel and reset case, other than to the connect one to
prevent the race that we could have when connecting to a cancellable
that is reset from another thread.
We don't really need to release the locks during callbacks now as they
are per instance, and there's really no function that we allowed to call
during a ::cancelled signal callback that may require an unlocked state.
This could been done in case with a recursive lock, that is easy enough
to implement but not really needed for this case.

Currently, the trash functionality is disabled for system internal mounts.
That might be a problem in some cases. The `x-gvfs-notrash` mount option
allows disabling the trash functionality for certain mounts. Let's add
support for the `x-gvfs-trash` mount option to allow the opposite.

We can only use the [class@Foo.Bar] syntax for identifiers under
namespaces included by the current namespace. Naturally, we cannot
include the GDK namespace.
Use a direct link for this instead.
Adjust all docs to use the gi-docgen referencing syntax, reindent
some of the comments, and add missing annotations to some async
methods.
The error arguments are not necessary with gi-docgen so they're
removed.
Confusingly enough, the docks for GAppInfo is spread between two
files.
This fixes commit cdcb179808.
`dn_comp()` is needed to build fake DNS records for most of the tests in
this file. The new ownership test is no exception.

On Linux the error will be `G_IO_ERROR_CONNECTION_REFUSED`, but on macOS
it will be `G_IO_ERROR_TIMED_OUT`. Both errors seem reasonable to me, so
let’s not specifically require one of them.

This should have been dropped in commit

and somehow it wasn’t caught by the CI until afterwards.

For each test expected to return valid DNS records, test that the
record variants are not floating references.
Also add an test which checks this explicitly for a simple TXT record.
The return value to `lookup_records()` methods is set as `transfer full`
but the code path in `g_resolver_records_from_res_query()` doesn't
sink the GVariant.
Add the `g_variant_ref_sink()` call when prepending the record, so
the list hold a full reference on each records.

- Add licensing tags
- Tweak spacing, colors, line thicknesses
- Create light-mode version
- Use `<picture>` tag to include appropriate version for each media
color scheme.
Recreate the `menu-model.png` diagram in SVG, with box outlines and
connectors recolored from black to white. This will allow the diagram
to show up better in the dark documentation theme.
When the file name is too long (for example, more than 238 bytes on
ext4), this will cause the creation of the .trashinfo file to fail.
Let's shorten the .trashinfo filename in this case, after all the
trash specification only requires unique filenames (see
`Contents of a trash directory` section in
https://specifications.freedesktop.org/trash-spec/trashspec-latest.html).
This should test the limits of loading 4GB files on i386 platforms, such
as the Hurd CI runner. On such platforms, `sizeof(size_t) == 4`.
This should fix the compiler warning from

They take too long to include in a normal test run. They’ll still be run
in CI once a week as part of our scheduled slow test job.

The tests - one for sync, one for async - create a sparse file for
this purpose, so this should be cheap on the fileystem.
Of course, the test still allocates >4GB of memory for the data that it
returns from g_file_load_contents(), I hope the CI test runners can deal
with that.
GByteArray is limited to 4GB in size and the current code silently
overflows when that happens.
Replace both load_contents() and load_contents_async() implementations
with a version that uses realloc() and gsize to maintain the array.
