Allow roff_parseln() to be re-run.

Allow roff_parseln() to manipulate the line buffer offset.  This is used
in situations like `.ie n .TH FOO 1' or `.ie n .ie n', where the line
buffer offset is recalculated then the roff parser re-run.
Fix mdoc_parseln() and man_parseln() to accept the initial line offset.
WARNING: backed-out ALL roff macros whilst accomodating for how roff
handles multi-line conditionals (in short, re-running the parser).
