Stuff tbl_calc() into out.c so that it can be shared by all output modes

(isn't now, but will need to be, used by -T[x]html also).  Necessitated
a lot of churn in getting tbl_calc* code out of tbl_term.c and into
out.c, including renaming some structures and so on.  The abstraction is
in having a pointer to a wrapper function for calculating string widths.
The char devices use term_strlen and term_len; the others will probably
just use strlen().

While at it, remove some superfluous assertions in the tbl code.  This
allows all tbl manuals to clear.

Lastly, set the right-margin to be the maximum margin for each table
span.  This allows big, complicated tbl-pages like terminfo to be
displayed.  They're ugly, but they work.
