`g_resources_get_info()` immediately frees. So let’s avoid allocating

The test in `unix-mounts` to see whether `g_unix_mounts_get_from_file()`
can parse an example file was working fine when GLib is built with
libmount, but not when built without it (and hence typically using
`getmntent()`).
This is because libmount supports mountinfo files (like
`/proc/self/mountinfo`), but `getmntent()` only supports mount files
(like `/proc/mounts`). The test was written only with the former.
So, change the test to use mount files when GLib is built without
libmount support.

This kind of deeply nested menu is definitely no longer good UI practice
for most apps (deeply nested menus make things hard to find, and require
good mouse control to navigate). However, it does serve as a good
demonstration of the concepts in `GMenuModel`, so keep it, with a
sentence to acknowledge that it’s not a good UI.

These tests are expected to cause a thread to deadlock. That seems to be
fine with glibc on Linux, but the glibc version on FreeBSD can detect
the deadlock, and aborts the whole test process with:
```
GLib (gthread-posix.c): Unexpected error from C library during 'pthread_mutex_lock': Resource deadlock avoided. Aborting.
```
This is fair enough.
To avoid this causing the test suite to fail, run those two tests in
subprocesses. This also means we’re not carrying a deadlocked thread
around for the rest of the test suite.

Move references to their equivalents from `GnomeVFS` to lower down in

This can never have been tested, it was returning `GUnixMountEntry`
structs from functions which are typed to return `GUnixMountPoint`s.

While GLib doesn’t parse these files, it does provide API to access the
fields from them, and does implement some logic based on options fields
in them. It would be nice to be able to test that, and get coverage of
the methods for `GUnixMountPoint` and `GUnixMountEntry`.
We don’t expect users to start querying the fstab or mtab by explicitly
loading data from those file paths. These functions are mainly intended
to prove a controllable entry point into the `gunixmounts.c` code for
unit testing.
It means we can provide a file with controllable contents in order to
test the mount entry/point code on.

You may not always know which schemes are available.
The library should not bail out, but only show
an informal message. It's the responsibility of
the application to deal with invalid URI schemes.
The test brings a Finder window to the front. It's not ideal,
but I have no better idea at the moment. It would be cool if we
can make the test case register itself as handler for a particular
uri scheme, but I have no idea how to do that.
I answered a question on irc about withdrawing notifications, and
when I handed out a link to the GApplication docs, I noticed we
don't have this function name linkified. Fix that.
On Wayland the activation token returned by
`g_app_launch_context_get_startup_notify_id()` doesn't depend on the
`GAppInfo`. The token is only used to hand over focus to the
application that is launched. In some cases it's not even possible to know
what application will actually be used to open the files. For example
when using portals within a sandbox. Therefore, allow providing no
`GAppInfo`.
This also makes clear in the docs that the `files` argument can be `NULL`.
We want to add the support for the activation token, to get it we use
`g_app_launch_context_get_startup_notify_id` which takes a list of
files, so that we don't have to create a GFile twice simply change the
signature of the functions. Fortunately this isn't a public API.
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

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.

If we enable `-Wfloat-conversion`, these warn about a possible loss of
precision due to an implicit conversion from `double` to some other
numeric type.
The warning is correct: there is a possible loss of precision here. In
these instances, we don’t care, as the floating point arithmetic is
being done to do some imprecise scaling or imprecise timing. A loss of
precision is not a problem.
So, add an explicit cast to squash the warning.

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

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.
Disable tests that require update-desktop-database when it is missing.
It requires glib to build so it will be missing when bootstrapping glib.

Previously it was mapped (as a default) to `G_IO_ERROR_FAILED`.
It’s the error that macOS returns when trying to connect to a socket which

It’s helpful if they both map to the same `GIOError` value.
