Do not mmap() with MAP_PRIVATE - looks like kernel tries to preallocate
...
some memory in case the mmapped contents would be changed and this fails
for very large files; it's unnecessary anyway, cmp(1) does not change file
contents in any way.
This fixes bin/10625 by Uwe Klaus.
While here, change the code to fallback to classic stdio if mmap fails.

don't warn about missing files with -s. POSIX doesn't define a specific

action, and, most other implimentations use this (sane) method. (from jtc).

As suggested by Xavier Leroy <xavier@Theory.Stanford.EDU>, make sure we don't
...
flag a short read on the 2nd file as an EOF when it isn't. This implementation
differs in that at most one read is done per file per comparison, so that an
early mismatch may avoid hanging on input or continuing some expensive process
if reading from a pipe.

Get rid of otoi(), use strtoul() instead. Not only gets rid of a function,

but allows hex offsets as well.
Misc other minor tweaks.

Changed to conform to POSIX.2:
...
EOF message printed to stderr.
Removed bogositys wrt. getopt() processing (special casing `-' is unnecessary).
Updated usage message to document fact that -s and -l options are mutually
exclusive.
