The state purpose of !3021 is to add a new fallback to `kgx`. This should not entail changing the order of the existing entries, which changes the order in which terminals are searched for. Move the new entry to the bottom, where fallback will still find it without changing the fallback order.
Inspired by libglnx's glnx_close_fd() and glnx_autofd, these let us
have the same patterns as g_clear_object() and g_autoptr(GObject), but
for file descriptors. g_clear_fd() is cross-platform, while g_autofd
is syntactic sugar requiring a supported compiler (gcc or clang).
Now that g_close() checks for EBADF as a programming error, we can
implement the equivalent of glnx_autofd as an inline function without
needing to have errno and EBADF in the header file.
g_clear_fd() is like glnx_close_fd(), but with error checking.
The private _g_clear_fd_ignore_error() function used to implement
g_autofd is a closer equivalent of glnx_close_fd().

C99 guarantees that va_copy() exists, so use it, instead of probing
for __va_copy(), va_copy(), or a reimplementation from first principles.

There is usually no reason to use the GLib-specific type names here,
other than consistency. The GLib-specific one-word type names can
sometimes be a little more convenient when generating a family of
function names from macros.
Because these types are simple aliases for a hard-coded standard C type,
there should be no API or ABI issues caused by changing existing code to
use the standard C names: a `char **` can already be used interchangeably
with `gchar **`, and name-mangling for a C++ method that takes an `int`
parameter is equivalent to a `gint` parameter.

Introduce support for terminals executing commands without an option,
i.e., the command is passed directly as argument to the terminal emulator.
This is needed for xdg-terminal-exec.
Get rid of multiple conditionals branch by using a loop and storing the
options needed by particular terminal emulators directly in an array.
Remove intermediate variable term_argv as we don't need it.
Advantages:
- simpler logic, less branching
- the terminal emulator list is more readable, by virtue of being
condensed in one array. Launch options to execute a terminal program
are also more explicitly specified
- the logic become independent from the order
- one less allocation
The gversionmacros.h header is referenced from glib/, so it needs to go
into glib's include directory, not in the top-level alongside glib.h,
glib-object.h, gmodule.h, and glib-unix.h.
The function adjusting private struct size to private struct offset
should be `g_type_class_adjust_private_offset`, instead of the
previously misspelled `g_type_class_add_instance_private` in comment.
Fixes#2791

It’s entirely possible that `g_file_read_link()` will return a relative
path. Mention that in the documentation, and include a short example of
how to make the path absolute for further computation.

The changes in 6265b2e6f70d6f0ec4d16adcdc5f7c53aecf0da4 to reject weird
`/etc/localtime` configurations where `/etc/localtime` links to another
symlink did not consider the case where the target of `/etc/localtime`
is a *relative* path. They only considered the case where the target is
absolute.
Relative paths are permissible in all symlinks. On my Fedora 36 system,
`/etc/localtime`’s target is `../usr/share/zoneinfo/Europe/London`.
Fix the check for toolbx by resolving relative paths before calling
`g_lstat()` on them.
