-----------
Fix session-lifespan memory leak when a plperl function is redefined:
we have to tell Perl it can release its compiled copy of the function
text. Noted by Alexey Klyukin.
Back-patch to 8.2 --- the problem exists further back, but this patch
won't work without modification, and it's probably not worth the trouble.
