Message:

sysinfo API cleanup

• better support for generated subtrees
• synchronization
• memory management (generated items cleanup)
• simplier sysinfo_dump()

remove separate statistical syscalls, replace with virtual sysinfo items (some functionality is still missing)

• naming consolidation
• cleaner API
• proper synchronization

minor renames

• zone_print_list() → zones_print_list()
• zone_busy_and_free() → zones_stats()
