various system information. * Implemented retrieving some VM stats via this call. * The VM now maintains a page fault counter, and sets system_info::page_faults accordingly. * Added a (pretty simple) "vmstat" command line app. * Minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27597 a95241bf-73f2-0310-859d-f6bbb57e9c96
