refers to the size of the whole ethernet packet, just the DHCP
message within the UDP payload, or something else. bootpd interpreted
it as a maximum UDP payload size, so it could end up sending
fragmented packets to clients (such as some versions of Etherboot)
that used different interpretations of the maximum message size.
Switch to the most conservative interpretation: ensure that the
ethernet packet containing the response is no larger than the
specified maximum message size. This matches the behaviour of
the ISC dhcpd.

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.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
