scan-build thinks that `gvs_variable_sized_array_is_normal()` can do a
`NULL` pointer dereference on `value.data` when `value.size == 0`. This
isn’t possible, because `offsets.length == 0` always when `value.size ==
0`, but that’s a bit of a complex relationship which the static analyser
can’t work out.
Give it some help by adding an assertion.

After a lot of loop unwinding, during which I think it might have lost
its knowledge that `cache->buffer != NULL` (from a prior check on line
765), scan-build seems to think that there can be a `NULL` pointer
dereference of `cache->buffer` within `cache_magic_compare_to_data()`.
There can’t be. Add an assertion to try and help the analyser.

scan-build thinks there can be a `NULL` pointer dereference in `while
((i = N_NODES (node->left)) != pos)`, if `node` is `NULL`.
`node` cannot be `NULL`, though, assuming the `n_nodes` member of each
node in the tree is an accurate count of the number of nodes beneath
that point. It controls the tree descent and avoids trying to descend
beneath a leaf.
A static analyser can’t know this though, so let’s add an assertion to
help.

scan-build thinks that it’s possible for `read_netlink_messages()` to
return `FALSE` and an unset error (or `TRUE` and a set error), and this
belief causes it to emit warnings for code which calls
`read_netlink_messages()`.
That’s not possible, but the function is written in such a way that
following the control flow would be hard for a static analyser. It would
have to work out that `retval` and `local_error == NULL` are identical
on all control flow branches.
Avoid the need for such complex analysis by eliminating `retval` and
just using `local_error` throughout.
This introduces no functional changes to the code.

scan-build thinks that `term_arg` could be used uninitialised. I think
there isn’t a bug here because that use is protected by the
`found_terminal == NULL` check and early return. But perhaps that logic
is a bit too complex for static analysis, so add a default value for the
variable.

The previous approach was to return a length as a `gssize`, with
negative values indicating failure. That works fine, but causes a lot of
signed/unsigned comparisons or assignments.
Tidy the code up by splitting success from length, returning success as
a boolean, and length as a `size_t*` out argument. This introduces no
functional changes, but does tidy the code up and fix some compiler
integer warnings.

Looks like the original author mixed up where the link label and the
link URL goes. :p
Previously the link would point to "https://docs.gtk.org/gio/file
attributes", with a space and no file extension.
There is a meson option (gir_dir_prefix), but without being passed in here
the files would always get installed into the default location (datadir).

The recently added libmount-based unix mount monitoring may fail when the
device exceeds inotify limits. Let's fallback to the older implementation
in case of the `mnt_monitor_get_fd` function failure. This among others
fixes tracker-miners failures caused by seccomp rules.

The define for g_utf8_next_char(p) includes a not needed final cast to
(char *). In fact, this cast has the adverse effect of causing a warning
if p is a (const char *) with gcc/clang compiler option -Wcast-qual.
So lets remove the not needed cast and add option -Werror=cast-qual
to glib/tests/utf8-pointer.c which uses g_utf8_next_char().
Now utf8-pointer.c compiles also with compiler option -Werror=cast-qual
and passes all tests.
This is a partial revert and rework of commit
c79575362e, for the `gsettings` script
only (the other completion scripts are fine).
I blindly added quoting to everything shellcheck told me to, without
testing it properly.
As it turns out, the `$schemadir` argument to `gsettings` invocations
was deliberately not quoted, so that it would expand to zero arguments
if unset, and two arguments (`--schemadir /some/path`) if set earlier in
the command-being-completed.
Quoting it meant that it expanded to one argument (the empty string) if
unset, which caused the `gsettings` subcommands to fail, and hence any
further tab completion to fail.
Fix that as suggested on https://www.shellcheck.net/wiki/SC2086 by
turning `schemadir` into an array, which either has zero members if
unset, or two members if set.

As suggested by Ville Skyttä in
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/4012#note_2084405,
make sure to invoke the copy of the command which is being completed
when asking for completions of a given subcommand.
This avoids accidentally invoking any old `gdbus`/`gresource`/etc.

Using the same justification as in
https://gitlab.gnome.org/GNOME/dconf/-/merge_requests/81#note_2083220:
it’s hard to get this right, with error handling, in a way which is
understandable to people reading it, and which both bash and shellcheck
will be happy with.
On the assumption that none of the completions generated by any of these
utilities will include ‘problematic’ characters (ones which would cause
word splitting or globbing in bash), just ignore the shellcheck
warnings. Note that I have not actually closely verified that these
utilities can’t return ‘problematic’ characters.
This means we can enable shellcheck, with fatal warnings, for these
scripts, and hence catch future regressions.
If someone wants to improve the handling of globbing/word splitting in
some/all of these array assignments in future, the shellcheck disables
can be removed.
