Move the last column-counting members of struct termp (col and maxcols)

from int to size_t, to match some existing ones (offset, *rmargin, viscol).
Move some related local variables from int to size_t as well.

Needed as a preparation to make a generalized adjbuf() function available
beyond the file term.c, i.e. in mandoc.c.
Also saves a couple of ugly casts.
