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()

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.
