Release ATK 2.38.0

See merge request GNOME/atk!49

And follow more idiomatic patterns for paths.

I double checked, and Debian stable (bullseye) ships with Meson 0.56.2.

So we don't need ancillary scripts to build ATK.

Use 0.52. It still is ancient, but that's what Debian stable uses.

We're still stuck on Fedora 31, which has been EOL'ed ages ago.

Don't use a specific version name, to avoid having to deal with updating
the image every time Debian does a new stable release.

It's been removed by recent GLib versions, and we're getting compiler
warnings. It also has never been appropriate to use `volatile`.

atk_value_get_value_and_text: cope with text being NULL

subprojects: Use GLib main branch

See merge request GNOME/atk!48

Use the depth= argument from Meson 0.52 to limit the clone depth of
subprojects to 1. This should make the CI images a little smaller, and
reduce the bandwidth required to build them (although that’s not so
important because it only happens once every few months).

GLib upstream has renamed its `master` branch to `main`.

meson: fix pkg-config generation with internal dependencies

See merge request GNOME/atk!39

When building with internal dependencies (subprojects) meson fails to
configure the build with the following message:

subprojects/atk/atk/meson.build:161:10: ERROR: requires argument not a string, library with pkgconfig-generated file or pkgconfig-dependency object, got <InternalDependency null: True>

Use libraries instead of requires when calling pkgconfig.generate() to
make the configuration succeed.

Change inspired by
https://gitlab.freedesktop.org/libnice/libnice/commit/ff75be1b19fc2599fda520321649da32625c561d

At-spi2-core has ATSPI_STATE_COLLAPSED, and java-atk-wrapper is actually missing it.

Use the correct element, and the correct email address.

The autocleanup symbols for ATK introduce new API, and the only way for
dependent libraries to check for them is to use the version that
introduced them.

Add autocleanup definitions

Closes #10

See merge request GNOME/atk!41

The G_DEFINE_AUTOPTR_* macros are used to define various symbols needed
in order to use the g_autoptr() macro in GLib, which are a requirement
in order to use the G_DECLARE_* macros to cut down the GObject
boilerplate in the headers.

Fixes: #10
