* Initialize the local recording of the user S/MIME cipher preferences.
* This function is called once for each cipher, the order being
* important (first call records greatest preference, and so on).
* When finished, it is called with a "which" of CIPHER_FAMILID_MASK.
* If the function is called again after that, it is assumed that
* the preferences are being reset, and the old preferences are
* discarded.
*
* XXX This is for a particular user, and right now the storage is
* XXX local, static. The preference should be stored elsewhere to allow
* XXX for multiple uses of one library? How does SSL handle this;
* XXX it has something similar?
*
* - The "which" values are defined in ciferfam.h (the SMIME_* values,
* for example SMIME_DES_CBC_56).
* - If "on" is non-zero then the named cipher is enabled, otherwise
* it is disabled. (It is not necessary to call the function for
* ciphers that are disabled, however, as that is the default.)
*
* If the cipher preference is successfully recorded, SECSuccess
* is returned. Otherwise SECFailure is returned. The only errors
* are due to failure allocating memory or bad parameters/calls:
* SEC_ERROR_XXX ("which" is not in the S/MIME cipher family)
* SEC_ERROR_XXX (function is being called more times than there
* are known/expected ciphers)
