Start actually inserting full utf8 sequences

This makes it possible to cut-and-paste the UTF8 testfile into a new
buffer, and the end result looks correct.

NOTE! We still do various things wrong while editing.  For example,
while the cursor movements were fixed, simple things like deleting a
character still work on single bytes, rather than utf8 characters.

So while this is getting much closer to actually editing UTF-8 data,
it's not there yet.
