Make expr POSIX-compliant, and fix some bugs.  Specifically:

- expr must conform to the Utility Syntax Guidelines, so use
getopt() to eat the (non-existent) options.

- Use the Standard type intmax_t for arithmetic.

- If an argument cannot be *completely* converted to an integer, then
it is a string.

Additionally make some style cleanups near the modified lines.  This
utility is still not completely style-compliant.
