Marcel Moolenaar 8ef94ce860 Fix bootpd for Alpha.
bptypes.h originally defined int32 to be of type long. This obviously
doesn't work on the Alpha. By defining int32 (and u_int32) in terms of
int32_t (and u_int32_t) it now is what it says it should be.

Two occurrences of 'unsigned int32' have been changed to 'u_int32' for
consistency.
