nfs4.1: Minimal SP4_MACH_CRED implementation
This is a minimal client side implementation of SP4_MACH_CRED. It will
attempt to negotiate SP4_MACH_CRED iff the EXCHANGE_ID is using
krb5i or krb5p auth. SP4_MACH_CRED will be used if the server supports the
minimal operations:
BIND_CONN_TO_SESSION
EXCHANGE_ID
CREATE_SESSION
DESTROY_SESSION
DESTROY_CLIENTID
This patch only includes the EXCHANGE_ID negotiation code because
the client will already use the machine cred for these operations.
If the server doesn't support SP4_MACH_CRED or doesn't support the minimal
operations, the exchange id will be resent with SP4_NONE.
