Unify roff macro argument parsing (in roff.c, roff_userdef()) and man macro
argument parsing (in man_argv.c, man_args()), both having different bugs,
to use one common macro argument parser (in mandoc.c, mandoc_getarg()),
because from the point of view of roff, man macros are just roff macros,
hence their arguments are parsed in exactly the same way.
While doing so, fix these bugs:
* Escaped blanks (i.e. those preceded by an odd number of backslashes)
were mishandled as argument separators in unquoted arguments to
user-defined roff macros.
* Unescaped blanks preceded by an even number of backslashes were not
recognized as argument separators in unquoted arguments to man macros.
* Escaped backslashes (i.e. pairs of backslashes) were not reduced
to single backslashes both in unquoted and quoted arguments both
to user-defined roff macros and to man macros.
* Escaped quotes (i.e. pairs of quotes inside quoted arguments) were
not reduced to single quotes in man macros.
OK kristaps@
Note that mdoc macro argument parsing is yet another beast for no good
reason and is probably afflicted by similar bugs. But i don't attempt
to fix that right now because it is intricately entangled with lots of
unrelated high-level mdoc(7) functionality, like delimiter handling and
column list phrase handling. Disentagling that would waste too much
time now.
