BELPIC (BELgian Personal Identity Card) is the official electronic ID
card of Belgium.

Start adding a virtual implementation of this card to vsmartcard.

Not remotely there yet, but at least this runs without error already,
and sends the correct ATR when asked. Beyond that... much TODO.

The BeID card does not allow the user to create extra files, so disallow when
it is tried

Current BeID development tools work with XML files to represent the data
on the card. Reuse that format, so that existing developers don't have
to regenerate their cards (and so that a certain level of
interoperability between those tools exists)

We may add another option in the future, but that's not for now.

Also, add the Belpic applet's AID as the DF name for the MF

TODO: generate it here, rather than there. Not for now.

(and trigger a travis build while we're at it)

The basic VirtualSmartcard implementation parses and logs the APDU sent
to the card in the execute instance method, and logs the received APDU
after calling that method.

The Relay implementation, however, overrides the execute method, but
does not log it. The result, when running at the info log level, is that
you see the reply from the card, but not the request from the
application. This is confusing.

Additionally, if the relay implementation shows the request APDU, then
it can be used as a method to analyze what an application is trying to
do.

To remedy all that, parse the APDU and log that parsed value, but don't
do anything further with it.

Some unknown cards, which the Relay card may need to deal with, may not
use the APDU format. Trying to parse commands sent to those cards as
though they were in the APDU format is obviously wrong. However, most
cards do support APDU, so default to logging parsed APDUs, still.

Also, implement a stub version of the "GET CARD DATA" and "LOG OFF"
commands that are proprietary to the Belpic applet.

Now that we have a correct ins2handler dict, drop the unneeded create
method

The spec for the Belgian electronic ID card interprets the ISO 7816
"SELECT FILE" command in a somewhat simplified way. First, the MF (3F00)
can be selected from anywhere when P1 = 0x02; second, child DFs are
selected also with P1 = 0x02. The applet does not interpret or treat
specially cases where P1 = 0x00 or P1 = 0x01.

In order to not to have to rewrite the "select file" logic that already
exists in the Iso7816OS class, filter those two commands so that they
contain the P1 value which the Iso7816OS class would search for.

The belpic applet does not deal with file sizes. It just returns less
data than was requested, and the remote is supposed to figure out that
the file was smaller than it assumed before based on that. It still
returns SW12 0x9000 in that case, however.

Add a "formatResult" method which filters out the SW12 = 0x6282 case, so
that applications don't see values they don't expect.

Otherwise the file is unavailable and the eid-mw PKCS#11 module
complains that the card is broken.
