Make it obvious that the function always returns a valid pointer and fix
all callers.

util: rewrite auto cleanup macros to use glib's equivalent

Since commit 44e7f02915
util: rewrite auto cleanup macros to use glib's equivalent
VIR_AUTOFREE is just an alias for g_autofree. Use the GLib macros
directly instead of our custom aliases.

Now that 100% of libvirt code is forbidden in a SUID environment,
we no longer need to worry about whether env variables are
trustworthy or not. The virt-login-shell setuid program, which
does not link to any libvirt code, will purge all environment
variables, except $TERM, before invoking the virt-login-shell-helper
program which uses libvirt.

By making use of GNU C's cleanup attribute handled by the
VIR_AUTOPTR macro for declaring aggregate pointer variables,
majority of the calls to *Free functions can be dropped, which
in turn leads to getting rid of most of our cleanup sections.

Libvirt, on its own, shouldn't decide whether an expired lease should
stay in the custom leases database or not. It should rather rely on
the 'DEL' event from dnsmasq.

The implementation is pretty straightforward. Moreover, because
of the nature of things, gethostbyname_r and gethostbyname2_r can
be implemented at the same time too.

This function is going to be used later in such context where the
argument makes no sense. Teach this function to cope with that
instead of the caller having to deal with passing some dummy
argument.

These functions are going to be reused very shortly. So instead
of duplicating the code, lets move them into utils module.
