	* configure.in etc
	Consolidate some of the Kerberos checking instead of repeating
	the same things for MIT and Heimdal.
	Also adds more checks to distinguish 32-bit from 64-bit
	(mainly for gssapi.h)
	Fix svcgssd Makefile so make TOP=../../ works correctly there.
	Enable running a modern autoheader.
	* utils/gssd/gss_oids.c: Use correct OID value for SPKM-3
	* utils/gssd/gss_util.c: Fix build with older MIT releases that do not define GSS_C_NT_HOSTBASED_SERVICE
	* utils/gssd/write_bytes.h, support/include/gssapi/gssapi.h:
	Length of gss_buffer_desc is a size_t which is 64-bits on a
	64-bit machine.  Kernel code expects 32-bit integer for length.
	Coerce length value into a 32-bit value when reading from or
	writing to the kernel.
	Change gssapi.h to use datatype size values obtained from
	configure rather than hard-coded values.
	* utils/idmapd/idmapd.c: The EV_INIT check here was wrong, and was
	causing idmapd to become unresponsive to server requests after
	receiving a sighup.
	* utils/idmapd/idmapd.c: Idmapd should flush the server id<->name
	caches when its started.
