I ran Bustle/dbus-monitor on the session bus while running the full GLib
test suite, and noticed that these tests were causing `Launched` signal
emissions on the main session bus. That suggested they weren’t isolated
properly, which at best causes noise on the bus and at worst could cause
spurious test failures.
Fix that by running those tests in a `GTestDBus` environment, as some of
the other appinfo tests already are.

They get at least these `GIBaseInfo` subclasses up to a reasonable (but
not complete) coverage level.

These follow GObject conventions, using `G_TYPE_CHECK_INSTANCE_CAST` to
cast to the given type, and potentially performing some runtime checks
of the type instance’s `GType` too.

Just like is done with `g_object_{ref,unref}()`, make these functions
take a `void*` rather than a `GIBaseInfo*`, since they’ll most likely be
called with a type which is derived from `GIBaseInfo*` rather than a
`GIBaseInfo*` itself.
Add some runtime type checks to make up for lowering the compile time
type safety.

This means they’re now using the `GType` type system rather than the old
`GIInfoType` type system. Given the preceding few commits, these two
systems should now be equivalent.
This makes the type handling more conventional and hence a bit simpler
for people to use if they have experience with GObject.

There are various info types which were previously treated as subtypes
of `GIRegisteredTypeInfo` by the runtime type system in the old version
of libgirepository.
Change the new type tree to reflect that, making several types now be
subtypes of `GIRegisteredTypeInfo`, and making `GIRegisteredTypeInfo`
abstract.

Boxed types are already represented within `GIInfoType`, so they should
have a `GType` representation as well.
In an upcoming commit, this will allow us to represent the subtype
relation between `GIBoxedInfo` and `GIRegisteredTypeInfo` too.

Flag enums are already treated as a special kind of enum within
`GIInfoType`, so it would be tidier to give it its own `GType` too, with
a subtype relation to `GI_TYPE_ENUM_INFO`.
This will simplify implementing `GI_IS_ENUM_INFO` in a following commit
too.

Previously (and incorrectly), `GICallableInfo`, `GIFunctionInfo`,
`GICallbackInfo`, `GISignalInfo` and `GIVFuncInfo` were all derived
directly from `GIBaseInfo`. `GICallableInfo` is supposed to represent
all of the other types, though, so that type hierarchy was incorrect. It
dated from when all the types were aliases of each other and the type
management was done entirely at runtime.
Fix that by making the other four types derive from `GICallableInfo`,
and marking `GICallableInfo` as abstract.

This doesn’t change the type hierarchy for now (i.e. it introduces no
functional changes), but it will allow us to add some intermediate types
into the `GIBaseInfo` hierarchy in an upcoming commit.

Do this by tracking the state of the size/alignment calculations
separately, rather than bunging it into the `alignment` field using

It’s not useful for lcov to demand branch coverage of all branches
within `g_clear_*()` functions (such as `g_clear_pointer()`). By
choosing to use `g_clear_*()`, the programmer explicitly doesn’t care
about whether the pointer is `NULL`. The tests shouldn’t have to either.

`-1` isn’t part of `GIArrayType`, so it’s not particularly type safe to
return it from `gi_type_info_get_array_type()`. Instead, make it an
error to call that function on a type which isn’t an array type.

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.
