library; add more of my gratuitous changes, <STAT> api

Browse Source 
This commit is just my usual tweaking after an initial
submission, once the dust has settled & some more desk
checking was performed. Here are the changes included:

. get function need not check the 'stat_was_read' flag
( first time in save_sec == 0 so branch always taken )

. some table logic appeared outside the proper section
. cleanup_stack's loop made to work like assign_result
. eliminated an include of procps.h from stat.h header
. removed 'ext_numitems' from the stacks_extent struct
. changed the alignment of three prototypes for stat.h
. reorganized the pointers for 'stacks_extents' struct
. improved types indentation in header for readability

. lastly, some really gratuitous changes made to align
- comments within that private 'stacks_alloc' function
