* Add recipe for 1.8 and use a mirror redirector for SOURCE_URI.
* Sort cmd:* in PROVIDES and BUILD_PREREQUIRES and add cmd:less to
the latter since less(1) is required for "make check".
* Add TEST() with "make check". Test results: PASS = TOTAL = 18.
* Drop removal of lib/charset.alias as it has disappeared.
* this fixes the wrong recipe names introduced by myself in #d525fee
* adjust patch names to match corresponding recipes
* additionally: create 'additional-files' folders as hint to some
ports that do not have a proper recipe yet
