pkcs11x.h missing

[Nikos Mavrogiannopoulos]

Hello,
 I am trying to use blacklists from the p11-kit trust module, and
according to documentation in [0], CKA_X_DISTRUSTED must be specified
when looking for a blacklisted certificate. However, this definition is
only available in pkcs11x.h which is not installed. Even more, I think
it would be more convenient if that file was included by default by
pkcs11.h so one could simply check for that functionality with an
#ifdef CKA_X_DISTRUSTED.

regards,
Nikos
