Windows expects the containerName field in TSSmartCardCreds to be what
it would use for a smartcard key's name. Try to accomodate that (at
least for PIV and GIDS cards).
Some WCHAR string constant were wrong (missing \x00 at the end).
The commit also implements the NCRYPT_READER_PROPERTY property in the pkcs11 provider.
This implements the emulation for the ncrypt API and more specifically the smartcard
provider so that we can list available keys and certificates using pkcs11-helper.
