Prototype of unicode readline support

The readline functionality operated on the assumption that 1 byte = 1
character. This is obviously wrong if you input a non-ascii character.
This commit temporarily removes a lot of functionality but parses input
bytes in a unicode-aware manner.

The outstanding problem now is 1 unicode rune != 1 column. There are
double wide characters, as well as zero width runes, that further break
our assumption that 1 rune = 1 character = 1 column. This is the next
iteration.
