Classic snaps are just a kind of packages with no sandbox at all, so
there's no point to mark them as sandboxed.
In this way we can just do IO checks once without having to multiply
them.

Meson now uses find_program() to get glib-mkenum from glib instead of
from system. That was already fixed at least in >=0.60 which is our
current minimum requirement.
This is a spiritual follow-up to commit 8cff531520, which
added `G_TEST_OPTION_ISOLATE_DIRS` to the `gdbus-connection-flush` test
to avoid its D-Bus cookie lock file from being erroneously deleted by
other tests running in parallel.
The same failure mode could affect any of the other D-Bus tests which
connect to a bus. As an easy fix, enable `G_TEST_OPTION_ISOLATE_DIRS`
for all of them.
The only test it’s not (yet) enabled for is `gdbus-address-get-session`
as that messes around with `XDG_RUNTIME_DIR` to test finding the session
bus. It might be possible to use `G_TEST_OPTION_ISOLATE_DIRS` with it,
but that would take longer than I have right now.
In any case, the more tests (which try to connect to a bus) that this is
enabled for, the lower the chances of spurious test failure due to them
conflicting over shared resources.

It sometimes fails under valgrind, and is pointless: if the test is
wedged, it’s better to catch that with the timeout at the level of
`meson test`, which can be tailored (using `-t`) to the test environment
and wrapper.

Instead, iterate the `GMainContext` directly. This allows tests on
asynchronously returned values to be done in the actual test function,
rather than a callback, which should make the tests a little clearer.
This introduces no functional changes.

This makes the code a little easier to understand and allows the kernel
a little bit more leeway in scheduling the callback, which is fine
because we don’t need high accuracy here.

`g_notification_backend_new_default()` adds a reference on
`backend->dbus_connection` (if non-`NULL`), but nothing ever unreffed
that.
Fix that by adding a dispose method.
In practice this is not really a problem, because the notification
backend is held alive by a `GApplication`, which lives as long as the
process. It’ll be a problem if someone is to ever add unit tests for
`GNotificationBackend`s though. So let’s fix it.

Add a few missing introspection annotations too.
This doesn’t change any of the ownership handling behaviour, just
documents what’s there. What’s there seems to be correct, to the extent
that I can see.

The code is correct, but from a quick read-through it wasn’t entirely
clear to me how it handled floating `GVariant`s in object state or the
`parameter` argument.
Add an assertion and some comments to hopefully clarify things a little.

Do not use can_run_host_binaries() as it returns true even though
custom_target() does not currently correctly wrap target-built
tool binaries with exe_wrapper so they can be run on the host.

Building GLib 2.75.0 on Linux adds various inotify-related internal
symbols to the ABI, which doesn't seem to have been intentional.
I went through the other libraries in the build system, and it looks
as though the BSD kqueue backend would have the same problem.
GNU symbol visibility probably doesn't do anything for gio/win32, but
for completeness I've set that to use hidden symbols too, on the basis
that it'll be easier to get this right if we're consistent.

This typically indicates a bug in the program, where a GTask has been
created, but a bug in the control flow has caused it to not return a
value.
There is one situation where it might be legitimate to finalise a GTask
without returning: if an error happens in your *_async() start function
after you’ve created a GTask, but before the async operation returns to
the main loop; and you report the error using g_task_report_*error()
rather than reporting it using the newly constructed GTask.
Another situation is where you are just using GTask as a convenient way
to move some work to another thread, without the complexity of creating
and running your own thread pool. GDBus does this with
g_dbus_interface_method_dispatch_helper(), for example.
In most other cases, it’s a bug. Emit a debug message about it, but not
a full-blown warning, as that would create noise in the legitimate
cases.

the gio dbus codegen test has 10 test cases in it.
Each test case is given 100 seconds to complete.
That is far longer than they should need.
Furthermore, the entire test is only given 60s
to complete.
This commit makes the internal timeout more consistent
with the external timeout, by giving each of the 10
test cases 6 seconds instead of 100s.
That’s what xdgmime uses for zero-sized files (see `XDG_MIME_TYPE_EMPTY`).
Historically, GLib explicitly used `text/plain` for empty files, to
ensure they would open in a text editor. But `text/plain` is not really
correct for an empty file: the content isn’t text because there is no
content. The file could eventually become something else when written
to.
Text editors which want to be opened for new, empty files should add
`application/x-zerosize` to their list of supported content types.
Users who want to set a handler for `application/x-zerosize` on their
desktop should use
```sh
gio mime application/x-zerosize # to see the current handler
gio mime application/x-zerosize org.gnome.gedit.desktop # to set it
```

`HAVE_COCOA` should be used only in the places where we’re actually
depending on the Cocoa toolkit. It should not be used as a general way
of detecting building on a Darwin-based OS such as macOS.
Conversely, there are a few places in the code where we do want to
specifically detect the Cocoa toolkit (and others where we specifically
want to detect Carbon), so keep `HAVE_COCOA` and `HAVE_CARBON` around.

Helps: #2802
This reverts commit 476e33c3f3.
We’ve decided to remove `G_OS_DARWIN` in favour of recommending people
use `__APPLE__` instead. As per the discussion on #2802 and linked
issues,
* Adding a new define shifts the complexity from “which of these
platform-provided defines do I use” to “which platform-provided
defines does G_OS_DARWIN use”
* There should ideally be no cases where a user of GLib has to use
their own platform-specific code, since GLib should be providing
appropriate abstractions
* Providing a single `G_OS_DARWIN` to cover all Apple products (macOS
and iOS) hides the complexity of what the user is actually testing:
are they testing for the Mach kernel, the Carbon and/or Cocoa user
space toolkits, macOS vs iOS vs tvOS, etc

Some of GLib's unit tests are under an apparently GLib-specific
permissive license, vaguely similar to the BSD/MIT family but with the
GPL's lack-of-warranty wording. This is not on SPDX's list of
well-known licenses, so we need to use a custom license name prefixed
with LicenseRef if we want to represent this in SPDX/REUSE syntax.
Most of the newer tests seem to be licensed under LGPL-2.1-or-later
instead.

In g_proxy_resolver_lookup_async() we have some error validation that
detects invalid URIs and directly returns an error, bypassing the
interface's lookup_async() function. This is great, but when the
interface's lookup_finish() function gets called later, it may assert
that the source tag of the GTask matches the interface's lookup_async()
function, which will not be the case.
As suggested by Philip, we need to check for this situation in
g_proxy_resolver_lookup_finish() and avoid calling into the interface
here if we did the same in g_proxy_resolver_lookup_async(). This can be
done by checking the source tag.
I added a few new tests to check the invalid URI "asdf" used in the
issue report. The final case, using async GProxyResolver directly,
checks for this bug.
Fixes#2799
Similar to g_source_set_static_name, this avoids
strdup overhead for debug-only information in
possibly hot code paths.
We also add a macro wrapper for g_task_set_name that
uses __builtin_constant_p to decide whether to use
g_task_set_name or g_task_set_static_name.
We already set names on most sources, this
one was just forgotten. This lets us set
a static name, and prevents g_task_attach_source
from setting a non-static one.
