g_object_weak_ref() documentation refers to GWeakRef as thread-safe
replacement. However, it's not clear to me, how GWeakRef is a
replacement for a callback. I think, it means, that you combine
g_object_weak_ref() with GWeakRef, to both hold a (thread-safe) weak
reference and get a notification on destruction.
Add a test, that GWeakRef is already cleared inside the GWeakNotify
callback.
Adapt gi-compile-repository sources to compile against the updated
libgirepository that is included with GLib.
This also renames "g-ir-compiler" to "gi-compile-repository" to avoid
overwriting the existing binary and to simplify the binary name going
forward.
For the same reasons as in commit 71061fdcb3, but in this
case we can’t downgrade the version of Meson on the CI runner, so just
tell it to shut up instead.

This was introduced by me in commit
1eec66c898, as the ownership transfer
semantics of `gi_typelib_new_from_mapped_file()` were not blatant.

To enable tests which depend on libgirepository's GIR and typelib,
we need to refactor the order we're currently building these items.
We can also move everything under girepository/ to cleanup the
top-level.
also, make the global variable "static const". That may allow the linker
to place the variable into read-only memory, so we are a bit more confident
that it cannot be modified.
We now only support creating `GIRepository` instances as normal
GObjects, not as a global singleton. This makes the semantics of the
class a bit more standard and, in particular, makes it easier to ensure
that everything is freed when we’re done with libgirepository. This is
particularly useful for unit testing, but should also be useful when
unloading modules from bindings.

Rather than them being set and stored globally, make them members of
`GIRepository`. This helps us move away from the concept of a global
singleton `GIRepository`.
This is slightly complicated by the fact that the library paths are
needed within the module loading code in `GITypelib`, but at that point
the `GITypelib` doesn’t have access to its parent `GIRepository` to call
`gi_repository_get_library_path()`, so we have to cache them in
`typelib->library_paths`.
It also means that it’s no longer possible to retrieve the ‘unset’ paths
from the globals, so the test for that is removed from
`repository-search-paths.c`.
This commit makes some API breaks, but that’s OK because libgirepository
has not been in a stable release yet.

This means they’re implemented in the same file as the typelib search
path, so it’s easier to refactor the code.
This adds `gi_repository_get_library_path()` to expose the library path,
both publicly and to internal users in `gitypelib.c`. And unit tests.

`GBytes` provides a way of handling const memory blobs, stolen memory
blobs, and mapped files. Rather than having `GITypelib` implement all of
those itself, just take a `GBytes` as input.
This is an API break, but libgirepository hasn’t been in a stable
release yet.

`GIIrNodeUnion` is built dynamically at runtime (rather than being
mmapped from disk), so its types can accurately reflect their runtime
semantics, rather than an on-disk format.
As part of this, switch from `atoi()` to `g_ascii_string_to_unsigned()`
for parsing the relevant fields from a GIR XML file. This means we now
get error handling for invalid integers.

`class_closure` isn’t actually meaningfully set anywhere in the code yet
(there are FIXME comments), so I’m not sure of the best type for it. But
generally `unsigned` is more widely used than signed `int`.

`g_strdup(NULL)` is guaranteed to return `NULL`, so there’s no need to
branch to handle that.
Add a stub private doc comment to hold a `(nullable)` annotation for
that argument, though, so that information isn’t lost.

Might as well move to a modern way of declaring GObjects. This means
that `GIRepository` is no longer derivable, but it would be a bit

This is just for future reference for people reading the code in future.
I was going through and checking to see if any of them needed to be made
`const` (none of them did).
I did find a couple of memory leaks though; see the following commits.

By shifting responsibility for ensuring that the lifetime of a
`GIRepository` always exceeds the lifetime of any of its `GIBaseInfo`s
to the user.
Keeping a weak ref from each `GIBaseInfo` to its `GIRepository` would be
too expensive (`GIBaseInfo`s are supposed to be cheap to create and
destroy, as they are used within function calls in language bindings).

Don’t allow the `pages` job to be run (even manually) on post-merge
pipelines. It’s not particularly useful, and GitLab doesn’t like having
a manual job with unsatisfied dependencies in a pipeline:
```
'pages' job needs 'coverage' job, but 'coverage' is not in any previous stage
'pages' job needs 'style-check-advisory' job, but 'style-check-advisory' is not in any previous stage
```

g_strndup() internally uses strncpy(), while g_strdup() uses memcpy().
Most likely, memcpy() is faster.
Instead of strlen()+g_strndup(), use g_strdup() as we don't need the
length.
In some merge requests there are bits (such as memory leaks) that we may want
to test before merging and that the schedules will run them.
As per this add a rule to make them manual, and apply it to some jobs.
This fixes many things from the port to gi-docgen, but also improves
documentation more generally.
Main improvements/fixes:
- Fix links to functions, constants, etc.
- Rewrite code syntax to work with Markdown
- Reduce indentation (do not indent by 4 to prevent code blocks)
- Remove redundant text such as "can be NULL" or "should be freed"
- Move text from large return info texts to main function text
- Remove periods at the end of parameter and return descriptions
- Do not capitalize the first word of a parameter or return description
- Try to improve consistency between docs for similar functions
- Convert %TRUE and %FALSE into true and false
- Convert other uses of `%` and `#` into inline code
