procps/proc/pids.h
Jim Warner 0360f64027 library: refactor all the readproc.h 'PROC_FILL' flags 
The 'PROC_FILL' flags, found in readproc.h, had become
almost unmanageable. The hex values were scattered all
over the map as new flags had been introduced. So this
commit resets all of them and will help ensure any new
flags don't duplicate some already existing hex value.
