Sync our temporary internal copies of these functions with parserutils (which is rather better tested and fixes a number of known bugs in NetSurf's previous UTF-8 handling). Ideally, this will be the only place in NetSurf that has any dependency on parserutils, so port the amiga font code to our internal APIs. svn path=/trunk/netsurf/; revision=6550
