In C, a function called 'func' which has once_had_no_optargs=true will
(because of the previous commit) generate 'func_opts' and a
backwards-compatibility function called 'func'.
This commit changes some of the non-C bindings so that they also
generate 'func_opts' which is merely a wrapper that calls 'func'.
This avoids incompatibility when we rename 'mkfs_opts' etc back to
plain 'mkfs', and it also makes it easier to translate between other
language bindings and C code.
NB: Some bindings do not include aliases:
PHP: There's no way to easily alias methods in PHP < 5.3, and we
can't assume everyone has this minimum version.
GObject: Very complex to add aliases, but we should probably do this
at some point.
Haskell: No support for optargs in these bindings. Unfortunately
this means that we can no longer bind 'Guestfs.add_drive'
(since it will be changed to add optional arguments) making
the Haskell bindings even less useful than they were already.
