Make OpenSC PKCS#11 Vendor Defined attributes, mechanisms etc unique
Make OpenSC PKCS#11 Vendor Defined attributes, mechanisms etc unique

This will help when p11-kit is usead and wil allow for additional
CK*_* things to be defined that have a much better chance of being
unique.

OR in "OSC" to any CK*_VENDOR_DEFINED thing.
with #define SC_VENDOR_DEFINED 0x4F534300  /* OSC */

This follows Netscapes convention of doing the same but
using: #define NSSCK_VENDOR_NSS 0x4E534350 /* NSCP */

The current 2 defines  CKA_* are for internal attributes.
