The attached patch provides the following output when run with the -G
option (for 'G'et version):

	% /usr/build/obj/x86_64/usr/src/libexec/httpd/bozohttpd -G
	bozohttpd version bozohttpd/20160415
	%

Does anyone have any objections to adding this?  I want most pieces of
network-facing software and/or high-value target clients to be able to
self-identify.

Thanks,
Al
