This reverts commit 50d432c77b.
The platform-specific headers of GLib and Gio are now introspected
separately, so the documentation for them can be built separately, and
this workaround is no longer needed.

It was causing a build failure on some platforms:

Instead, add a method on `GIRegisteredTypeInfo` which indicates whether
the registered type is a boxed type. This will return true for
`GIStructInfo` and `GIUnionInfo` instances which are boxed (not all
structs and unions are).
This makes `GIBoxedInfo` redundant, and it’ll be dropped in a following
commit.
---
There are several different things which typelibs need to be able to
represent:
1. Plain old datatype (POD) structs
2. POD unions
3. Structs with a copy func and/or free func
4. Unions with a copy func and/or free func
5. Structs which are the ‘GType struct’ for an object or interface (i.e.
the class or instance or interface struct)
6. Structs with a copy func and free func *and* boxed GType
7. Unions with a copy func and free func *and* boxed GType
8. Boxed GTypes which represent something other than a struct or union
So there’s a lot going on here. In commit
e28078c70cbf4a57c7dbd39626f43f9bd2674145, a lot of this was reworked,
and support was added for boxed unions and boxed ‘others’ (the last item
on the list above).
Since then, support for boxed types other than structs seems to have
atrophied a bit, and the whole lot has got a bit confusing.
It was perhaps less confusing when all the `GIBaseInfo` subclasses were
actually aliases of each other, but now they have subtype relationships,
the position of `GIBoxedInfo` in that type hierarchy has become unclear.
How is it related to `GIStructInfo`, `GIUnionInfo` and
`GIRegisteredTypeInfo`?
Since a boxed type is necessarily a `GIRegisteredTypeInfo`, and the
methods of `GIRegisteredTypeInfo` are all written to allow a `GType` to
be optional, so that `GIStructInfo` and `GIUnionInfo` can safely derive
from it and still be used to represent plain old datatypes without
`GType`s, it makes sense to add a method to `GIRegisteredTypeInfo` to
indicate that the registered type is derived from `G_TYPE_BOXED`.
Accordingly, the things above are now represented in libgirepository’s
type system as:
1. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info
2. `GIUnionInfo` instance similarly
3. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info, `gi_struct_info_get_{copy,free}_function_name()` return
non-`NULL` values
4. `GIUnionInfo` instance similarly
5. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info, `gi_struct_info_is_gtype_struct()` returns true
6. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return valid
`GType` information, `gi_registered_type_info_is_boxed()` returns
true, `gi_struct_info_get_{copy,free}_function_name()` return
`NULL` values (because the copy/free functions are hidden inside the
boxed type registration at runtime)
7. `GIUnionInfo` instance similarly
8. Not representable, but could be represented in future by re-adding a
`GIBoxedInfo` type which derives from `GIRegisteredTypeInfo` and is
used solely for boxed ‘other’ types, *not* boxed structs or unions

When creating `GIBaseInfo` instances from binary blobs, so far the code
has used an undocumented implicit conversion from one enum type to the
other. That’s a bit nasty, as it means the two enum types need to be
kept in sync (without that need being documented).
Introduce an explicit conversion function to make things more explicit.
Currently it does nothing, but in an upcoming commit it will be used to
deprecate a blob type.

While it’s an internal API which `girwriter.c` has access to, it’s not
available inside `libgirepository-internals.so`. This wasn’t spotted
before commit 343027d5d landed because none of the existing users of
`libgirepository-internals.so` use the relevant code in `girwriter.c`,
so it got compiled out (`libgirepository-internals.so` is statically
linked and can be optimised like this).
Now that `gi-decompile-repository` uses the relevant code from
`girwriter.c`, the problem is obvious and `gi-decompile-repository`
fails to link.
Fix that by no longer using `gi_base_info_get_info_type()` in
`girwriter.c`. These are changes which would have eventually been made
anyway in issue #3253.

`--version` is conventionally used to find the version of the program

Rename them to `gi-decompile-repository` and `gi-inspect-repository` to
match the existing `gi-compile-repository`. The names have to differ
from those used in girepository-1.0 to avoid collisions.
‘generate’ has been changed to ‘decompile’ because it does the inverse
of what `gi-compile-repository` does: it converts a typelib to a GIR
file. ‘generate’ never really made much sense for this anyway — it’s
almost a synonym of ‘compile’.

This reverts commit 94273b0ebf.
Meson 1.2.0 contains a fix for the underlying issue (in commit
bd3d2cf91894b1f91128011b2cf56a5bd2c326ae), and we now depend on 1.2.0.
So the workaround is no longer needed.

GLib is used a subproject with GObject Introspection and overriding
this binary breaks that usage. For now we will make overriding the
binary conditional until Meson is updated to handle the binary changes.

The copy of this function that moved to glib-unix.c still needs to
implement the fdwalk-style interface, but this copy does not, allowing
us to turn it into a very simple syscall wrapper. Its remaining callers
never check for errors, and it never failed anyway, so remove the
returned value.

These are the same as Linux `close_range (lowfd, ~0U, 0)` and
`close_range (lowfd, ~0U, CLOSE_RANGE_CLOEXEC)`, but portable.
Unlike some implementations of BSD closefrom(3), they are
async-signal-safe.
The implementations were moved from the GSpawn code, which already
needs all of this functionality anyway, with the exception of
set_cloexec() which was copied (leading to some minor duplication,
but it's very simple).

They don’t need to be listed there in order to be built, and doing so
just means they get pulled into the `g-ir-scanner` command for building

These can then be used by a parent project if GLib is used as a Meson
subproject.
In particular, GJS wants to use `GLib-2.0.typelib`
from GLib-as-a-subproject, but doesn’t want to hardcode the path to it
inside the GLib builddir.
