Guy Harris 59caec8a01 Have signature_verify() do the copying and clearing.
Just pass it a pointer to a routine to do the clearing and a pointer to
the data that needs to be cleared; signature_verify() will relocate all
pointers to stuff that needs to be cleared to point into the copy, clear
the signature itself, and call the routine to clear anything else.
