top: trade most pids_stack pointers for a WIN_t ppt ix

Browse Source 
For every function whose parameters consist of a WIN_t
pointer and a pointer to a pids_stack, we will instead
pass the WIN_t pointer and index to that window's ppt.

This change will save six instructions per invocation,
and converts the index once in those called functions.

[ you can consider this an efficiency change, but it ]
[ is really being implemented so that 'TREE_FOCUS_X' ]
[ #define can be made to behave as one should expect ]
[ when running under top's 'alternate display' mode! ]

[ stay tuned for the very next commit to be pushed!! ]
