Re: 12.1 not useable: clientlib fails after a dozen queries (GSSAPI ?)

And here's a delta patch for that.  This fixes an additional portability
hazard, which is that there were various places doing stuff like

		input.length = ntohl(*(uint32 *) PqGSSRecvBuffer);

That's a SIGBUS hazard on alignment-picky hardware, because there is
no guarantee that a variable that's just declared "char ...[...]"
will have any particular alignment.  But malloc'ing the space will
provide maxaligned storage.

My FreeBSD testing has now given me enough confidence in these patches
that I'm just going to go ahead and push them.  But, if you'd like to
do some more testing in advance of 12.2 release, please do.
