Initial chunks for variable-width fonts. Pushes all width calculations

in mdoc_term.c and man_term.c down into term.c.  This is still not
implemented in term.c, although stubs for width calculations are in
place.  From now on, offset, rmargin, and other layout variables are
abstract screen widths.  They will resolve to the the familiar values
for -Tascii but -Tps will eventually use points instead of chars.
