* sysdeps/linux/*.h: added some new function suffixes:
'__l' is a function defined in the client part;
'__s' is a function defined in the sysdeps part and
'__p' is a function that needs special priviledges.
'__r' is mapped either on '__l' or on '__s'.
* sysdeps/linux/glibtop_server.h: New file -
defines system dependent constants 'GLIBTOP_SUID_<feature>'
being either 'GLIBTOP_SYSDEPS_<feature>'+1 depending upon
whether or not this feature requires using the server.
Things may now temporarily get instable; I'm currently implementing some
suggestions Sebastian Wilhelmi has made.
