Log Message:
To ease cleanup of the options namespace, add code to support legacy
option names:

PKG_OPTIONS_LEGACY_OPTS+=	old:new

If PKG_DEFAULT_OPTIONS or PKG_OPTIONS.foo contains option old (or
-old) it is rewritten to new (or -new) and a warning is issued by
the supported-options-message target.
