Another change I'm making to the arith code is making || return 0 or 1
only, matching C, POSIX and other shells.
Apart from the compliance issue, it is also bad to expose implementation
details like the exact meaning of 'noeval' to scripts such that they may
come to depend on them.

Jilles Tjoelker reported that binary operator parsing doesn't
respect operator precedence correctly in the case where a lower-
precedence operator is followed by a higher-precedence operator,
and then by a lower-precedence operator.
This patch fixes this by stopping when we encounter a binary
oeprator with a precedence lower than one that we have already
encountered.

Although in posix, imaxdiv() isn't implemented on Debian/alpha, causing
dash to fail to build. So use / and % operators if imaxdiv() isn't
available.

This patch adds assignment operator support in arithmetic expansions. It
also changes the type used to intmax_t.
