userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@. With help from dlg@ and millert@.

# 1.5 03-Feb-1999 millert

Fix broken conversion of private err() function and make ierr() and oerr()
back into functions, not macros. Also make functions that call mmap()
return an int so we can fall back to non-mmap (slow) version on mmap failure.
Noticable effects:
o when you tail multiple files, if one of the files doesn't exist or
is otherwise broken, keep on going to the next file.
o it is now possible to tail files > 2gig, though it will be *very* slow
since tail will be unable to use mmap()
