	This is now a LibGTop backend which can be loaded additionally
	to the normal Linux sysdeps code.

	* open.c, close.c: Removed.
	* shm_limits.c, msg_limits.c, sem_limits.c, ppp.c: Removed.
	* siglist.c, sysinfo.c: Removed.

	* backend-kernel.c: New file.
	* glibtop-backend-private.h: New file.
	* libgtop-kernel.backend: New file.

	* backend-kernel.pl: New file. Automatically creates
	`backend-kernel.h'.

	* marshal.pl: New file. Automatically creates `marshal.c'.

	* glibtop_server.h: Replaced all `GLIBTOP_SUID_<feature>' constants
	with `GLIBTOP_IMPL_<feature>' ones; they're used in marshal.c to
	find out which features this backend implements.

	* *.c: Renamed all `glibtop_get_<feature>_s' functions to
	`glibtop_get_<feature>_k' and all `glibtop_init_<feature>_s' ones
	to `glibtop_init_<feature>_k'.
