Eventually, we want to move to using `GType` directly for everything,
since `GIBaseInfo` and its subclasses are all using `GTypeInstance`.
However, that requires quite a lot of changes and we’re about to hit the
API freeze.
So do the smallest set of changes possible to remove `GIInfoType` and
related functions from the public API, which gives us freedom to make
more changes later without breaking API.

It’s actually a factory method rather than a constructor, since

This is needed because `GITypelib` is exposed in the public

Since `GITypelib` is exposed in the public libgirepository API, it needs
to be a boxed type. So we either need to add a `copy` method to mirror
the existing `free` method, or switch to refcounting. The latter option
seems better, since a `GITypelib` contains internal state about open
`GModule`s and the semantics for copying that would be potentially
complex.

This effectively reverts commit 0910e2f6ad. I thought that `GIInfoType`
was decoupled from `GITypelibBlobType`, but it turns out that
`girepository.c` calls `gi_info_new_full()` with blob types, implicitly
converting them to info types.
This was causing anything with a type higher than the `INVALID_0` value
to be loaded as the wrong type.

Fix the declaration and documentation of
`gi_object_info_find_method_using_interfaces()` and
`gi_object_info_find_vfunc_using_interfaces()`. The documentation was
wrong when I wrote it: the value returned is the object or interface
which declares the method or vfunc, not the one which implements it.
The returned declarer info may be a `GIObjectInfo` or a
`GIInterfaceInfo`. Since those two types have no subtype relation
between them, the return type has to be changed to `GIBaseInfo`. Using
`GIObjectInfo` would have been fine in girepository-1.0 because all
`*Info` types were aliases of each other — but since the move to
`GTypeInstance` this is no longer true.

GI_IS_REGISTERED_TYPE_INFO() wasn't working because it was actually

Add some desultory type-checking assertions to the repository tests.
gi_repository_enumerate_versions() was missing a type check of the

girepository 1.x where the parameter was allowed to be null.
There are a handful of APIs in libgirepository which are used on
performance-sensitive code paths in language bindings (such as looking
at arguments when doing function calls). Historically libgirepository
has provided a stack-allocated variant for them, which avoids returning
a newly allocated `GIBaseInfo`. Since moving to glib.git and porting to
`GTypeInstance`, that stack allocated version has been broken.
This commit fixes it, by exposing obfuscated stack allocatable versions
of `GITypeInfo` and `GIArgInfo`, which are the two `GIBaseInfo`
subtypes which can be returned by the stack allocation functions.
The commit includes unit tests for them.

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.
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

This test case was originally written by Philip Chimento as a reproducer

Signed-off-by: Philip Withnall <pwithnall@gnome.org>
Helps: #3218
Most of the code for handling stack-allocated infos was correct, it was
just missing code to initialise the `GTypeInstance` member.
Since `GTypeInstance` isn’t really designed for stack allocation, this
is a little hacky — it requires setting up the member within
`GTypeInstance` manually. It works, though.
The externally visible consequence of this, though, is that
stack-allocated `GIBaseInfo`s now need to be cleared when they’re
finished being used. This allows the `GTypeClass` ref to be dropped.
All users of the stack-allocated APIs in libgirepository will need to
adapt to this change.

Note that for alignments we should actually use size_t, but this would
imply some refactors since this value can be acually set to -1 in our
implementation.
So we use gssize for now, that at least on gcc is defined.
We are using various indexes types, but not always using the correct
sign or size, so let's adapt this to ensure we're consistent with the
values we're comparing with.
Even though we expose member access as size_t, a GI info blob can
typically just access to an a number of values that is never bigger
than uint16_t, as that's how the typelib is defined (cfr. typelib
internal header blob sizes and n_* elements).
So let's avoid this to happen by adding a check.
We used to use unsigned values, while they should be big enough to old
the data we're handling here, it's cleaner and clearer if we use size_t
as type for such values, as it makes straight forward to understand what
a value should contain. It also makes these values more future proof.
We just do a safe s/gsize/size_t/ replacement here without doing any
changes to places in which different size of size_t and gsize may be
actually different and create troubles.
The "--code" option was removed years ago in d5b8d8d523c3bc26aa9fe6c364d3a17d325b55b6

Return a non-zero result when opening the output file fails and
don't use g_error() for other failures when writing out the file,

We never actually include multiple modules in the compiler,
so just nuke that. Also rather than passing around GIrModule
consistently pass around a GIrTypelibBuild structure which
has various things.
This lets us maintain a stack there which we can walk for
better error messages.
Also, fix up the node lookup in giroffsets.c; previously
it didn't really handle includes correctly. We really need to
switch to always using Foo.Bar (i.e. GIName) names internally...
It can't really work right now because we rely on dumping data at runtime,
which requires the library. If in the future we support static scanning,
we can reinvestigate embedded typelibs.

It was deprecated since before libgirepository was moved into this
repository. Take the opportunity now to remove it entirely, as it’s a
bit confusing to have it in the public API.
This should not affect the binary typelib format, as it still has its
`BLOB_TYPE_INVALID_0` member, and that will remain in place until the
binary format next breaks compatibility (no plans to do that).
This is an API break in libgirepository, but since it’s not been in a
stable release yet, that’s fine.

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.

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).
