Improve (or rather, rewrite) tbl(7) option parsing.

* Allow the layout to start after the semicolon on the options line.
* Ignore leading commas.
* Option arguments cannot contain closing parentheses.
* Avoid needless UNSUPP messages.
* Better ERROR reporting.
* Delete unused "linesize" field in struct tbl_opts.
* No need for static buffers.
* Garbage collect one almost empty wrapper function.
Improved functionality, but minus 40 lines of code.
