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.
