The state machine is used to convert a stream of UTF8 data into UCS4
characters. It is slightly based on the machine found in the
wayland-compositor demos.

Allow converting a ucs4 string into a utf8 string. Also export the default
symbol so other subsystems may use it.

Instead of allocating big buffers with kmscon_char's for every character we now
reduce a single character to an integer. This integer is either the Unicode
codepoint or an ID to an internally allocated string.
The so called kmscon_symbol_t integer can now be used as if it were a classic
"char" value without bothering with combining marks etc.
