update some functions to the new standard name
but I might change that standard name.

try to improve performance of the DEBUG_r checks
unfortunately the name used for the struct regexp varies from
function to function.

simple resource limits
CPU limits work
I don't have good (adhoc) test for memory yet.
For now this only checks:
- memory - depth of backtracking
- CPU - counts the loops around the main loop in S_regmatch()
If there's other code that can end up using significant amounts of
memory (ignoring eval blocks), the counts need to be adjusted
to match.
There's still some FIXME for the DEBUG_r() handling which is too
expensive for now.

WIP make debug mode controllable for re.pm
FIXME: currently this does a lookup for every DEBUG_r(), which is
expensive
