In 2009, kristaps@ decided that using EN as the basic unit for horizontal widths on terminal output devices was the simplest option. It made sense because one EN is the smallest possible horizontal cursor movement on a terminal. In 2014, kristaps@ implemented the 'u' unit (BU, "basic unit") for scaled width input as 1/24 EN, but all internal variables continued to store widths in units of EN. This causes compatibility problems with groff, which internally represents widths in units of BU rather than EN. Various high-level macros internally calculate sums of user-controlled widths with a sub-EN precision. In mandoc, the coarse internal representation causes rounding errors, in some cases resulting in wrong indentations. Fix this by changing many internal variables in the terminal formatter to store widths in units of BU instead of EN, improving compatibility. An example of a manual page where mandoc output becomes more compatible with groff output is clang(1) - a page generated by the atrocious rst2man(1) tool, which insists, among other insanity, on indenting by non-integer multiples of EN. This patch includes the following related changes: * The termp.advance and endline functions now update termp.viscol. * Rename termp.width to termp.getwidth to help grep(1). * Delete term_hen() which becomes the same as term_hspan(). * Delete the unused struct termp_tbl. * Delete the unused tbl_sulen functions. In the tbl_term formatter, pass an additional coloff argument to all the data and fill functions, to deal with mismatches between the desired and the actual cursor position: the desired position is now maintained with BU precision, but the actual position is of course still an integer multiple of EN. Also simplify tbl_literal() by leaving TERMP_CENTER and TERMP_RIGHT adjustment to term_flushln(), which already contains code for that very purpose. We are really lucky to have the regress/ test suite. Without it, tricky and pervasive low-level refactoring of this kind would be impossible because it would unavoidably cause lots of regressions.

delete the unused function term_tab_iset(); even tbl(7) no longer needs it

Provide a cleanup function for the term_tab module, freeing memory and resetting the internal state to the initial state. Call this function from the proper place in term_free(). With the way the module is currently used, this does not imply any functional change, but doing proper cleanup is more robust, makes it easier during code review to understand what is going on, and makes it explicit that there is no memory leak.

Because mandoc_aux.h and mandoc.h use __attribute__, all files that include mandoc_aux.h or mandoc.h need to include config.h, too. It is suspected that for example IRIX needs this, or it is likely to throw errors in these files because the system compiler doesn't understand __attribute__. Issue reported by Kazuo Kuroi <kazuo at irixnet dot org>.

Basic implementation of the roff(7) .ta (define tab stops) request. This is the first feature made possible by the parser reorganization. Improves the formatting of the SYNOPSIS in many Xenocara GL manuals. Also important for ports, as reported by many, including naddy@.
