Meson 0.54.0 added a new method meson.override_dependency() that must be
used to ensure dependency consistency. This patch ensures a project that
depends on glib will never link to a mix of system and subproject
libraries. It would happen in such cases:

The system has glib 2.40 installed, and a project does:
dependency('glib-2.0', version: '>=2.60',
  fallback: ['glib', 'glib_dep'])
dependency('gobject-2.0')

The first call will configure glib subproject because the system libglib
is too old, but the 2nd call will return system libgobject.

By overriding 'gobject-2.0' dependency while configuring glib subproject
during the first call, meson knows that on the 2nd call it must return
the subproject dependency instead of system dependency.

This also has the nice side effect that with Meson >0.54.0 an
application depending on glib can declare the fallback without knowing
the dependency variable name: dependency('glib-2.0', fallback: 'glib').

So long, and thanks for everything. We’re a Meson-only shop now.

glib-2-58 will remain the last stable GLib release series which is
buildable using autotools.

We continue to install autoconf macros for autotools-using projects
which depend on GLib; they are stable API.

With this, the compatibility version and current version values in macOS
and iOS dylibs will match the values set by Autotools.

They only contain old information which is also available in git

-z nodelete breaks the libresourceplugin module usage in the resources.c
test, which expects to be able to unload it.

Make the Meson build match what the autotools build does: only pass
glib_link_flags to the headline libraries (glib-2.0, gio-2.0,
gobject-2.0, gthread-2.0, gmodule-2.0) and omit it from all other build
targets.

This requires improved pc file generator from meson 0.45.

Properly define GLIB/GOBJECT_STATIC_COMPILATION when static build is enabled.
Use library() instead of shared_library() to allow selecting static builds.

configure_file() forces utf-8 atm but .rc files are not utf-8.
To work around the issue just remove the only non-ASCII char.
