Runs verification on a signature, returning a result. The function will
retrieve the key needed to verify the signature if that hasn't already
been done, and if called from the final
callback, compare the computed body hash to the one found in the
Upon completion of processing of the signature, the caller may use

final callbacks, if defined.

- A positive result from dkim_sig_getflags() after calling
this function during the prescreen callback is not sufficient to
conclude that the signature is good, since at that time a final result
from dkim_sig_getbh() is not available. The latter must be
tested in the final callback to ensure that the signature was good
and the signature's body hash matched the one computed by the
