reimplement expr using lexical parser generated by yacc
...
highlights:
* / is treated correctly depending upon context (addresses PR # 10995)
* use 64 bit arithmetic, so expr is able to process integer values from
-(2**63) to (2**63 - 1)
* checks for integer over- & underflows added
* error messages improved, more error checking added
add AUTHOR section to manpage
add BUGS section, and mention possible drawbacks with other expr implementations
XXX the old expr treated empty string in arithmetic expressions as if it was 0
XXX this behaviour has been retained

Re-implemented with a recursive descent parser.

Fixed subtle bug wrt. comparing integers when either one hasn't been
coersed from a string --- while avoiding an even subtler bug found in
GNU expr.
