        Bug 149631 – gnome-terminal doesn't combine combining chars in utf8

        * src/vteunistr.c:
        * src/vteunistr.h:
        An extended UTF-32 type that assigns numeric values to UTF-8 sequences
        on demand.  Can be used to efficiently store a string, instead of one
        character, at each cell.

        * src/vte-private.h:
        * src/vte.c:
        * src/vtedraw.c:
        * src/vtedraw.h:
        * src/vtepangocairo.c:
        Port to vteunistr instead of gunichar for cell content.  
        
        * src/vte.c: 
        Handle zerowidth insertions by sticking it on the previous cell.

        * src/iso2022.h:
        * src/iso2022.c:
        Cleanup ambiguous-width handling.  Handle zero-width chars.
