Introduce GlobalPlatform SCP02 implementation

Browse Source 
This implementation of GlobalPlatform SCP02 currently only supports
C-MAC and C-ENC, but no R-MAC or R-ENC yet.

The patch also introduces the notion of having a SCP instance associated
with a SimCardCommands instance.  It also adds the establish_scp0w and
release_scp shell commands to all GlobalPlatform Security Domains.
