Make /bin/expr support 64bit numeric range and range checks by default, again. This brings back the behaviour of expr in FreeBSD-4, which had been reverted due to an assumed incompatbility with POSIX.1 for FreeBSD-5.
This issue has been discussed in the freebsd-standards list, and the consensus was, that POSIX.1 is in fact not violated by this extension, since it affects only cases of POSIX undefined behaviour (overflow of signed long).
Other operating systems did upgrade their versions of expr to support 64bit range, after it had been initially brought to FreeBSD. They have used it for a decade without problems, meanwhile.
The -e option is retained, but it will only select less strict checking of numeric parameters (leading white-space, leading "+" are allowed and skipped, an empty string is considered to represent 0 in numeric context.) The call of check_utility_compat() as a means of establishing backwards compatibility with FreeBSD-4 is considered obsolete, but preserved in this commit. It is expected to be removed in a later revision of this file. Reviewed by: bde, das, jilles MFC after: 2 month (those parts that do not violate POLA)

expr(1): Add sh(1) versions of examples, remove an incorrect example.
The three examples are better done using sh(1) itself these days.
The example expr -- "$a" : ".*" is incorrect in the general case, as "$a" may be an operator.

Create a small library function, check_utility_compat(3), to determine whether a named utility should behave in FreeBSD 4.x-compatible mode or in a standard mode (default standard). The configuration is done malloc(3)-style, with either an environment variable or a symlink.
Update expr(1) to use this new interface.

EXPR_COMPAT should imply -e, since there is no way to specify it otherwise, and -e reflects the historic behavior of FreeBSD's expr.

The response to my POSIX interpretation request says that `expr' is required to be oblivious to overflow and to use the data type `long'. (Division by zero is undefined in ISO C so it's still OK to check for it here.) Add a new `-e' flag to get the old, more useful behavior.

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.
