+digest value from the PKCS7 structure: to add a signer to an existing structure.
An error occurs if a matching digest value cannot be found to copy. The
returned PKCS7 structure will be valid and finalized when this flag is set.

+If B<PKCS7_PARTIAL> is set in addition to B<PKCS7_REUSE_DIGEST> then the
B<PKCS7_SIGNER_INO> structure will not be finalized so additional attributes
can be added. In this case an explicit call to PKCS7_SIGNER_INFO_sign() is
needed to finalize it.
PKCS7_sign_add_signers() returns an internal pointer to the PKCS7_SIGNER_INFO
