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.
