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.

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 6265b2e6f7 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.

Standard C specifically does not guarantee this, and it's untrue on
CHERI architectures (which have 128-bit pointers into a 64-bit
address space, with the remaining bits used for a capability-like
mechanism).

When collecting varargs, ignore the NOCOPY_CONTENTS
flag for variants. That is what our docs advice for
refcounted types, and it fixes a regression that
was inadvertendly introduced when we stopped doing
some extra GValue copies.
Includes a test case by Philip Withnall.
Fixes: #2774
Dereferencing a pointer to a 64-bit object as though it was a 32-bit
object is the same as taking the least significant 32 bits on a
little-endian machine, but on a big-endian machine it is the same as
taking the *most* significant 32 bits, which would result in these hash
functions always hashing to zero. The /hash/int64/collisions and
/hash/double/collisions test-cases in glib/tests/hash.c detect this
and fail.
Instead, fetch the whole 64-bit quantity and do the bit-manipulation
to xor the more significant half with the less significant half in an
architecture-neutral way.

This implements https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/350
for GDBus's server implementation.
Abstract sockets belong to the network namespace instead of the mount
namespace. As a result, mount namespace-based sandboxes (e.g. Flatpak)
cannot restrict access to abstract sockets (and therefore GDBus's
unix:tmpdir= server addresses), at least for applications with network
access permission, which may result in sandbox escapes unless the
application running the GDBus server explicitly check that the connecting
process is not in a sandbox. As of the time of writing, no known
applications using GDBusServer does this.
Fix this by always using non-abstract sockets for unix:tmpdir=, which is
allowed by the DBus specification.
Previously it was marked as failing on macOS, but commit
ed3998b390 seems to have fixed that. yay!
