* nss/nss_files/files-network.c: Pass empty for new DB_LOOKUP args.

	(DATABASE): Define this instead of DATAFILE.
	* nss/nss_files/files-hosts.c: Likewise.
	(hostbyname): Use LOOKUP_NAME macro.

	* nss/nss_db/db-XXX.c: New file.
	* nss/Makefile (services): Add db.
	(libnss_db-inhibit-o): New variable.
	(libnss_db-routines): New variable.
	(distribute): Append db-XXX.c.
	(libnss_db.so): Depend on libdb.so and libnss_files.so.
	($(libnss_db-routines:%=$(objpfx)%.c)): New static pattern rule.

	* nss/nss_files/files-XXX.c (DB_LOOKUP): Add KEYSIZE and KEYPATTERN
	args, ignored.
	(DATAFILE): New macro.
	* nss/nss_files/files-parse.c (GENERIC): If undefined, define to
	"files-XXX.c".
	* nss/nss_files/files-rpc.c: Include GENERIC instead of "files-XXX.c".
	Pass db key args to DB_LOOKUP.
	(DATAFILE): Macro removed.
	(DATABASE): New macro replaces it, lacks "/etc/" prefix.

	* sunrpc/xdr.c: Remove malloc decl.
	* sunrpc/portmap.c: Likewise.

	* sunrpc/svc_tcp.c (abort): Don't declare.  Instead define as macro
	casting abort to fn returning bool_t.

	* nss/nss_files/files-parse.c [EXTERN_PARSER]: Do an extern decl of

	* Makeconfig (BUILD_CC): If undefined, define to $(CC).

	* sunrpc/rpc/types.h: Include stdlib.h instead of declaring malloc.

	* Makeconfig (built-program-cmd): Use $(rtld-installed-name) in place
	of ld.so so lookups for that soname find it.

	* nss/Makefile (libnss_dns.so): Depend on libresolv.so.
	(resobjdir, LDLIBS-nss_dns.so): Variables removed.
