Move (mostly) MI constants to proper headers

Most of the constants here are only defined if a specific header is in
scope. So move the machine-independent macros to those headers and lose
the header guards. Most of these should actually be typedefs but let's
change this when we're bumping the major since this technically has ABI
impact.

IDEA_INT RC2_INT and RC4_INT are always unsigned int
DES_LONG is always unsigned int except on i386

This preserves the existing situation on OpenBSD. If you're using
portable on i386 with a compiler that does not define __i386__,
there's an ABI break.
