c28065c606 Our mmap(2) has a limitation where the `offset' parameter must be
page-aligned.  cmp(1) should know about this flaw, and work around it.

While i was at it, fixed an uninitialized variable as reported by
-Wall.

2ae09ad871 When mmap is used, do an madvise(MADV_SEQUENTIAL) to make things
go much more quickly when file input is really done.  Of course, the
fully cached case will make no difference.

e526625999 I don't like what they did to cmp(1) in 4.4 Lite; now it whines all
the time, even with -s.  Make cmp SHUT UP about non-existant files
when run with -s.
