Description

AMPI uses sequence numbers that are ints, which may overflow if more than INT_MAX messages are sent from one rank to another. They should be unsigned ints with overflow handled properly.

This change makes the sequence numbers into CMK_REFNUM_TYPE which by default is an unsigned short: https://charm.cs.illinois.edu/gerrit/#/c/2187/
