	Mnemonic:	mbuf_api_test.c
	Abstract:	Unit tests for the mbuf common API functions.
				To allow the mbuf functions to be tested without the bulk of the
				RMr mechanics, we dummy up a couple of functions that are in
				rmr[_nng].c.

			will be tested when the mbuf_api_static_test code is used by the
			more generic RMr test.  So, not all fields in the realloc'd buffer
