When system calls indicate an error they return -1, not some arbitrary
value < 0.  errno is only updated in this case.  Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable).  these days, people use source.  these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)

rewrite to not use mmap(2). solves a bunch of issues:
- No more I/O related SEGVs (PR 2337?).
- Performance linear to size of output, not input file size, even for very large files.
  Same for -r.
- Reverse tail also works for very large files.
- Very large values of n possible, even for very large files. Same for -r.

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()
