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
of libgirepository now uses `GTypeInstance` and appears to still work
(it’s difficult to be entirely sure because there are no unit tests
yet).

Now that libgirepository uses `GI_AVAILABLE_IN_*` macros, that’s what
controls symbol visibility. The `_` prefixes are redundant, and out of
keeping with the rest of GLib.

Rather than a mix of structs being in `GI` and their methods being in
`g_`.
We’ve chosen not to use the `g_` namespace because a number of the
libgirepository class names are quite generic, so we’d end up with
confusing symbols like `GScopeType` and `GArgument`.

The pkg-config file sets the include directory to the level above
`girepository/`, just like with GIO, GObject and GModule.

Add the SPDX license runes to all the files which have an obvious
copyright header already. This is a mechanical edit.
