If we're using a Secure Channel Protocol, this will add overhead
in terms of the C-MAC appended to the C-APDU. This means in turn that
the useable length of the data field shrinks by a certain number of
bytes.
Let's make sure the SCP instances expose an 'overhead' property
of how much overhead they add - and that other commands use this to
determine the maximum command data field length.

In smart cards, we every so often encounter data types that contain a
bit-mask whose length depends on whether or not there are any of the
least-significant bits are set. So far we worked around this with
some kind of Struct('byte1', 'byte2'/COptional, 'byte3'/COptional)
approach.
Let's do thisin a generic way using the new StripTrailerAdapter.

GlobalPlatform requires the use of the KCV for DES + AES keys. Let's
implement that.
(11.8.2.3.3: "For all key types described in section B.6, the Key Check
Value shall be present.")

This adds an implementation of the GlobalPlatform SCP03 protocol. It has
been tested in S8 mode for C-MAC, C-ENC, R-MAC and R-ENC with AES using
128, 192 and 256 bit key lengh. Test vectors generated while talking to
a sysmoEUICC1-C2T are included as unit tests.

The key-id is actually a 7-bit integer and on the wire the 8th bit
has a special meaning which can be derived automatically.
Let's unburden the user from explicitly encoding that 8th bit and
instead set it automatically.

Using this command, one can change the life cycle status of on-card
applications, specifically one can LOCK (disable) them and re-enable
them as needed.

This allows us to perform STORE DATA on applications like ARA-M/ARA-D
after establishing SCP02 to the related security domain.
Change-Id: I2ce766b97bba42c64c4d4492b505be66c24f471e
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.
