top: just miscellaneous tweaks to code and/or comments

This patch represents the following minor adjustments:

. the official PROCPS_MEMINFO_VAL macro has become the
basis for our own abbreviated MEM_VAL derivative macro
just like was done for all the other newlib interfaces

. it felt like time to change those forest_?? function
names while maintaining their special relationships to
one another (alphabetic, with each 1 longer than prev)

. and some whitespace was altered and some lines added
