Sync tbl handling to bsd.lv release 1.10.9:

* .T} can be followed by a delimiter, then more data.
* Do not limit table column widths (improves terminfo(5)).
* Let numerical cells respect explicitly specified minimum cell widths.
* Let terminal output survive missing data cells.
* Parse and ignore arguments in parentheses on layout cell specifications.
* Move tbl_calc() into out.c such that it can be used by all frontends.
* Give tables an HTML class.
* Some cleanup in tbl -Thtml code.
