Log message:

	* config/aclocal.m4 (unet_CHECK_TYPE_SIZES): check size of void *,
	too, for ircd_snprintf.c

	* include/ircd_snprintf.h: documentation for ircd_(v)snprintf, in
	comments; mostly descended from the Linux manpage for printf, but
	also documenting the extensions.

	* ircd/ircd_snprintf.c: NULL dest is equivalent to going to a
	client; make 'q' be the same as 'L'; remove __inline__; only
	define EXTENSION if HAVE_LONG_LONG is defined
