	* src/server: Removed.
	* src/daemon/{server, version}.c: New files.
	* src/daemon/Makefile.am: Added `libgtop_server'; this has been
	moved here from `src/server' since it shares some source code files
	with the `libgtop_daemon'.

	* LIBGTOP-VERSION: Added `LIBGTOP_SERVER_VERSION'.
	* src/daemon/gnuserv.c, lib/open.c: Improved version check between
	client and server.

	* include/glibtop/output.h: Removed.

	* sysdeps/stub_suid: New directory. This is mainly used as example
	for people porting libgtop to other systems.

	* sysdeps/common/sysdeps_suid.c: New file.
	Defines `glibtop_init_hook_p'.

	* sysdeps/osf1/*.c (glibtop_init_<no-suid-feature>_s): New functions.
	(glibtop_init_<suid-feature>_p): New functions.
