And rename it to `gi_repository_get_shared_libraries()`. Previously it
returned a comma-separated string, which wasn’t particularly typesafe or
machine-friendly. Now it returns the same data as an array.
This is an API break in libgirepository, but since it’s not been in a
stable release yet, that’s fine.

Having it be nullable means the type system forces the caller to check
the result for nullability every time, even though it’s straightforward
for the caller to check the index argument in advance and guarantee a
non-`NULL` result.
Change `gi_repository_get_info()` to never return `NULL` to tidy this
up. This also brings it inline with other `gi_*_get_info()` functions,
which are not nullable.

A few applications such as gnome-music load the GIRepository typelib
and use it to adjust their search paths.
GLib 2.79.x now provides libgirepository-2.0.so.0 (GIRepository-3.0),
but each OS distribution is likely to have a transitional period during
which GLib's libgirepository-2.0.so.0 has become available, but bindings
like PyGI and gjs are still linked to gobject-introspection's
libgirepository-1.0.so.1 (GIRepository-2.0).
During this transitional period, interpreted languages that load the
GIRepository namespace could get the "wrong" version, which will result
in adjusting a search path that will not actually affect the language
binding's typelib lookup, and could also lead to symbol and type-system
conflicts.
We can avoid this collision by making GLib's GIRepository library refuse
to load versions of the GIRepository typelib that are not 3.0, and
similarly making gobject-introspection's GIRepository library refuse to
load typelib versions that are not 2.0. A relatively neat way to achieve
that is to make each version behave as if the other one doesn't exist.

The library shipped by gobject-introspection.git was
`libgirepository-1.0.so`, but for some reason (accident?), it was
accompanied by `GIRepository-2.0.gir`. That’s been the case for the last
6 years.
In moving libgirepository to glib.git, we’ve bumped the version to
`libgirepository-2.0.so`, and have changed the API.
In order to avoid a collision between the new `GIRepository-2.0.gir` and
the old `GIRepository-2.0.gir`, we can either:
* Rename the basename of the library (confusing).
* Re-version the whole thing to 3.0 (would mean it’s completely out of
sync with the rest of glib.git, and would lead to build system
misery).
* Re-version only the GIR file (a bit confusing, but hopefully less
confusing).
So I’ve done the final option: glib.git now ships
`libgirepository-2.0.so` and `GIRepository-3.0.gir`. This avoids
collisions with what’s shipped by gobject-introspection.git, while
hopefully still making some sense.
We considered using version number 2.1 rather than 3.0, but decided
against it because that makes it look like it’s compatible with version
2.0, which it isn’t.
Note that none of these changes touch the
`${prefix}/lib/girepository-1.0` and `${prefix}/share/gir-1.0`
directories. The version numbers in those refer to the versions of the
GIR and typelib file formats, which have not changed.

We used to store the search paths into a GSList but this is not
efficient for various reasons, so replace this with an array so that we
can replace return just a GStrv in the public API.
Generating gir and typelib files has inter-dependencies that may depend
on other elements.
For example, glib requires gobject and gdump generated files require
gmodule, so we've a cyclic dependency because gmodule requires gobject,
that requires glib.
To prevent this, let's just generate the introspection files at once in
a different meson file so that we don't have to deal with this.
As per this we could even revert commit fa37ab6d0 since gio is now
compiled before the gir files.
It’s not particularly necessary, and makes the build-time dependencies
more complex than they need to be, as it means that to generate
GLib-2.0.gir and GObject-2.0.gir, libgio.so (and its generated headers)
already needs to have been built.
See discussion on https://gitlab.gnome.org/GNOME/glib/-/issues/3164
These changes need to be replicated in gobject-introspection.git before
the problem can be solved, though, as that still has its own copy of
`gdump.c` (which it installs and uses).

This adds more type safety to libgirepository, and allows
differentiating the `GIBaseInfo` derived types using the type system.
Two new derived types had to be added (previously they were just a
collection of helper methods which worked directly on a `GIBaseInfo` and
didn’t check types): `GICallbackInfo` and `GIUnresolvedInfo`.
Further cleanups and refactoring might be needed on this, but the core
