2a6bf1fadb Memory's free, but all the world ain't a VAX anymore. Bring math.3 
kicking and screaming into the 1980's.  This change converts most of
the markup from man(7) to mdoc(7) format, and I believe it removes or
updates everything that was flat out wrong.  However, much work is
still needed to sanitize the markup, improve coverage, and reduce
overlap with other manpages.  Some of the sections would better belong
in a philosophy_of_w_kahan.3 manpage, but they are informative and
remain at least as reminders of topics to cover.

9772caa388 The references to scalbn and scalbnf should be scalb and scalbf. 
(The former are actually useful, and ieee_test(3) only documents
functions that aren't.)  Add a sentence describing the domain of
scalb() and scalbf().

457f6cd2d6 - gamma_r, lgamma_r, gammaf_r, and lgammaf_r were protected by _REENTRANT 
in math.h; the consensus here was that __BSD_VISIBLE was correct instead.

- gamma_r, lgamma_r, gammaf_r, and lgammaf_r had no documentation in the
  lgamma(3) manpage.

a9dbc63dc2 gamma(x) actually returns \log(|\Gamma(x)|), so correct the man 
page and add an historical note explaining this. This patch is
based on Stephen's.

We still need someone to implement tgamma.

aa842e6a12 Fixed missing quoting of >= (in ceil.3) and <= (in floor.3) by reverting to 
describing these operators in English.  This completes the fix in rev.1.3
(rev.1.2 got this wrong by describing wrong operators in English).

Fixed bitrot and improved English in the DESCRIPTION section.

4bd9ba3c2f Fixed some minor formatting problems to silence manck some more. 
Corrected some bogus cross references to man pages that we don't/won't
have and either deleted them, or found a more appropriate man page
that we do have.  Various other minor changes to silence manck.

Manck is currently down to about 200 lines of errors, down from
the 500 - 600+ when I started all this.
