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).

This property is supposed to be used by authors of applications that use GAppliaction to output the version by --version flag or otherwise if a version is needed.

Various distributions (mainly RPM based so far) make use of automatic
dependencies extracted from typelib files (they can require other typelibs
and also shared libraries)
Current features
* Print used shared libraries
* Print used typelib dependencies

Take a GError * for typelib loading code, validate the header. This
fixes bizarre errors from gjs where g_irepository_require would happily
load old typelibs.
People have wanted support for marking (out) on functions of the
form:
/**
* clutter_color_from_pixel:
* @pixel: A pixel
* @color: (out): Color to initialize with value of @pixel
*/
void
clutter_color_from_pixel (guint32 pixel, ClutterColor *color);
Where the caller is supposed to have allocated the argument; the
C function just initializes it. This patch adds support for this
argument passing style to introspection. In this case, we see the
(out), and notice that there's only a single indirection (*) on
the argument, and assume that this means (out caller-allocates).

Foreign structs are special in the sense that there might
be native bindings (for instance PyCairo for PyGI) that provides
the same functionallity as the introspected variant.

Parse the c:prefix from the .gir, include it in the header. Armed with this
information, we can now optimize lookups of GTypes because we
have the requirement that GTypes must start with the c:prefix. We do
fall back though if a lookup fails.
Broadly speaking, this change adds the concept of <vfunc> to the .gir.
The typelib already had most of the infrastructure for virtual functions,
though there is one API addition.
The scanner assumes that any class callback slot that doesn't match
a signal name is a virtual. In the .gir, we write out *both* the <method>
wrapper and a <vfunc>. If we can determine an association between
them (based on the names matching, or a new Virtual: annotation),
then we notate that in the .gir.
The typelib gains an association from the vfunc to the function, if
it exists. This will be useful for bindings since they already know
how to consume FunctionInfo.
We now support an extensible mechanism where arbitrary key-value
pairs may be associated with almost all items, including objects,
methods, and properties.
These attributes appear in both the .gir and the .typelib.
Add --all option, which is intended to show some information not
usually included in the GIR.
Currently, it shows the size of structs and unions.

Similar to GObject class structs, we pair up GInterfaces with
their C structures.
Also, move some GLib-specific things into glibast.py, and make
the naming more generic.
Inside glibtransformer, we now look at structures ending in "Class" and
see if they have an associated GlibObject (i.e. a structure of the same
name without the "Class" suffix). If found, pair them up.
The .gir file for <class> gains an attribute denoting its associated
class struct. Any <record> many now have a glib:is-class-struct-for
annotation which tells which (if any) <class> for which it defines the
layout.
In the .typelib, we record the association between the class and
its structure. Generic structures however just have a boolean
saying whether they're a class struct. (Going from a generic class
struct to its class should not be necessary).
Finally, we expose GIRepository APIs to access both bits of information
from the .typelib.

Field offsets are a) architecture dependent so they shouldn't be part
of the architecture-independent gir format which is installed in
datadir. b) Are architecture-dependent so they shouldn't be in test
expected output. Remove field offsets from girs.
(Virtual function and discriminator offsets are not removed, as they
aren't fully hooked up to the field-offset computation machinery yet.)
