As the groups are disambiguated by name via the `groups` hash table,
there is guaranteed to be at most one `GKeyFileGroup` instance per group
name, which means they can be compared for equality by `GKeyFileGroup`
pointer, rather than needing a `strcmp()`.
This speeds up key file parsing in all cases.

This allows it to be called on a substring of a larger string, without
having to allocate a nul-terminated copy of the substring with
`g_strndup()` before knowing that the key name is actually valid.
This speeds up parsing of highly invalid key files, but doesn’t affect
performance in the normal case of a valid key file.

It is exactly the same wrap as the one in WrapDB but with a different
name. That fix error when multiple projects uses pcre and they don't
have the same wrap name:
meson.build:1:0: ERROR: Multiple wrap files provide 'libpcre' dependency: pcre.wrap and libpcre.wrap
All these `gchar *`s are used as moving pointers into strings, being
incremented as the strings are parsed. They are never modified, so can
be `const`. This doesn’t speed anything up, but does allow removing some
casts and slightly improving type safety.

Closes#2518
Fix another variant of the previous commit, this time specific to the
idle callback of a method call on a subtree object, racing with
unregistration of that subtree.
In this case, the `process_subtree_vtable_message_in_idle_cb()` idle
callback already has a pointer to the right `ExportedSubtree` struct,
but again doesn’t have a strong reference to it.

If `g_dbus_connection_unregister_object()` (or `unregister_subtree()`)
was called from one thread, while an idle callback for a method call (or
a property get or set) was being invoked in another, it was possible for
the two to race after the idle callback had checked that the
object/subtree was registered, but before it had finished dereferencing
all the data related to that object/subtree.
Unregistering the object/subtree would immediately free the data,
leading the idle callback to cause a use-after-free error.
Fix that by giving the idle callback a strong reference to the data from
inside the locked section where it checks whether the object/subtree is
still registered.

This should ensure that all editors which support
https://editorconfig.org/ use 2-space indentation with spaces (not tabs)
by default.
This isn’t a full specification of the GLib coding style (see
https://gitlab.gnome.org/GNOME/gtk/blob/HEAD/docs/CODING-STYLE.md for
that), but is a correct subset of it.

This introduces no functional changes; it only simplifies the code.
Instead of maintaining a separate pointer to the backend iff it’s a
`GDelayedSettingsBackend`, just test the `backend` pointer’s type.

Previously, the delay-apply status of the parent `GSettings` object
would be partially inherited: `settings->priv->backend` in the child
`GSettings` object would point to a `GDelayedSettingsBackend`, but
`settings->priv->delayed` would be `NULL`.
The expectation from https://bugzilla.gnome.org/show_bug.cgi?id=720891
was that `get_child()` would fully inherit delay-apply status.
So, ensure that `settings->priv->delayed` is correctly set to point to
the delayed backend when constructing any `GSettings`. Update the tests
to work again (presumably the inverted test was an oversight in the
original changes).

`standard::name` must be available for `g_file_enumerator_get_child()`
to work. Emit a critical warning and return if it’s not. This is similar
to the existing behaviour in `g_file_enumerator_iterate()`.
