The documentation wasn’t clear about whether it did that, or ignored nul
bytes and continued to `n` bytes regardless.

Rather than looking for the group node by comparing each name in the
linked list of `GKeyFileGroup` instances, look up the `GKeyFileGroup` in
the hash table, then look up its `GList` node by pointer.

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.

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.

Add missing (nullable), and use 2-space indentation to avoid markdown
pre-formatted blocks when unwanted.

As this would have undesirable consequence.
Quoting Philip Withnall:
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2305#note_1294729:
The documentation never said anything about accepting absolute paths,
so any code which is relying on that is relying on undocumented
behaviour. We’re allowed to change that.

`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()`.
Improve the documentation to mention this.

Fixes: #2507
The code cannot function correctly if the `standard::name` attribute is
not present, so upgrade the existing warning to a critical warning and
return if it fails in `g_file_enumerator_iterate()`.

Helps: #2507
It was Red Hat specific when it was introduced in 2004, was never
supported by mount(8) upstream, and was removed entirely in 2008.
It’s confusing for GLib to keep references to it around.
Thanks to Karel Zak for digging up the history of it:

And thanks to Xidorn Quan for looking into it in the first place (see
!2298).
