Recent profiling and timings have resulted in improved
newlib performance. This patch completes that process.
It just normalizes naming conventions employed for all
allocations involving reaped stacks & history support.
The modules offering a 'reap' function will also offer
the now standardized corresponding STACKS_INCR define.
The modules which provide dynamic history support will
now have a separate #define called NEWOLD_INCR used in
allocations/reallocations. And, while values currently
are set equal to that STACKS_INCR value, in the future
some reason for divorcing those two may be discovered.
----------------------------- for future reference ---
In those modules which contain the STACKS_INCR #define
it is tempting to specify a large value so as to avoid
repeated calls to malloc/realloc. However, in doing so
an extra runtime price will be paid in 'cleanup_stack'
calls with any iterative programs like top or slabtop.
So, with the current values a balance has been sought.
