I've rebased and reposted the other patch ("Add on_trusted_init and
on_untrusted_init to plperl") and added it to the commitfest.

I've rebasing this one now and making one minor change: I'm adding an
if (not our $_init++) {
...
}
around the code that adds items to @EvalInSafe and @ShareIntoSafe to
avoid any problems with on_trusted_init code that causes exceptions.

Currently an exception from on_trusted_init will leave the plperl
interpreter in the 'not yet setup' state. So the next use runs
the plc_safe_ok code and the on_trusted_init code again.
This change makes the plc_safe_ok code idempotent so the re-execution
won't cause any problems (except for harmless warnings about the
safe_eval and mksafefunc subs being redefined).

Patch to follow (after getting the kids to bed).

Tim.
