The attatched patch solves the problem and I think it is more robust then 
adding a new function.
calling a function like the proposed zend_restore_user_opcode_handler() might 
be a problem in case someone else put handler before you.
instead of that it's easier to just tell zend_set_user_opcode_handler() to 
restore the opcode value in case the handler is NULL.
that will make the flow of zend_set_user_opcode_handler(<my_handler>) and then 
zend_set_user_opcode_handler(<orig_handler>) simpler.

a patch is attatched and tested.
