The length field in wavemobile sim cards is not set, so that the field
stays at its initial value, which is 0xFF. Lets write the correct mnc
length here.

At the moment EF.AD, which contains the length of the MNC is not
updated. For two digit MNC (the usual case) this is fine since the
length is set to 2 by default. However, when one wants to set an MNC
with 3 digit length the file must be updated, otherwise the third digit
of the MNC is recognized as part of the MSIN.

The hexadecimal tag defintions of pytlv are case sensitive strings. So
'A5' is something different than 'a5'. Pytlv uses lower case letters for
the upper hexadecimal digits. Lets correct this.

This interface allows to use a Calypso based phone (e.g. Motorola
C1XX) as a SIM card reader. It basically implements a few L1CTL
messages that are used to interact with the SIM card through
the OsmocomBB 'layer1' firmware.
Please note, that this is an experimental implementation, and
there is a risk that SIM programming would fail. Nevertheless,
I've managed to program and read one of my SIMs a few times.

When programming or reading a SIM with an IMSI shorter than 15, the IMSI
value is incorrectly encoded/decoded.
The code pads the the IMSI value with 0xF from the left but padding from
the right would be correct.
It also encodes the length as half the number of digits in the IMSI
(rounded up). This isn't correct for even length IMSIs. With even length
IMSIs, the odd/even parity bit bumps the last digit into an extra byte,
which should be counted as well.
- Fix endcoding of IMSI value
- Fix decoding of IMSI value

Closes: SYS#3552
Add support to handle Wavemobile sim cards. The support excludes some
parameters. For example it is not possible to write own KI keys yet.
Support covers the following files:
EF.SMSP
EF.IMSI
EF.ACC
EF.PLMNsel
EF.PLMNwAcT
EF.OPLMNwAcT
Not yet supported are:
EF.ICCID
KI (propretary file)
OPc (propritary file)

When sysmosom-gr1 is used with a custom ADM key, then the ADM string is
not fed through h2b() like we see it with sysmo-usim-sjs1 for example.
- feed the ADM to h2b() before use

Some of the USIM-Card programming implementations do not need to look
at card responses, which means they also do not have to parse TLV
data. Lets depend on pytlv only in cases where TLV data has to be
parsed so that useser of cards that do not need at can go without
installing pytlv.

The method update_plmnsel() does not return the status word yet, which
causes pysim-prog.py to print an error message that does not influence
the functionality but does not look nice.
- preserve the status word that is returned with update_binary() and
return it properly like the other methods do.

Some of the methods SimCardCommands() have ways to determaine length
information from the card response. Regular sims use a format where
the length field is on a fixed position. USIMs use FCP templates
(format control parameters), which is a TLV encodecs string. So lets
distingish if we deal with an USIM (We can easily do this by looking
at the select control parameters) and extract the length info from
the FCP.
- If we deal with USIMs, use the FCP to determine length
information

The method send_apdu() first transmits the APDU in the cards direction.
The card may indicate that there is a response available by responding
with SW1=9F, where SW2 is the number of bytes. send_apdu() will then
craft a get-response APDU to pickup the response bytes. This mechanism
works fine for SIM, but USIM uses SW1=61 to indicate the availability
of a response, so lets also sense on SW1=61 to support USIMs as well.
- Also check on SW1=61 to see if a response is available

The method send_apdu_checksw() is used to check the SW of the final
response against some pre defined value. However, in many cases the
last two digits of the SW are used to return varying information
(e.g. length information or a more specific status info). To cover
those cases it would be helfpul to define status words that contain
wildcards (e.g. 61**) in order to be able to accept all SWs from
6100 to 61ff.
- When the user supplies an expected SW with wildcards, mask out
those digits in the response before comparing

pySim has been using magic numbers to access various files which makes it hard
to read, maintain and extend. With this file in place we can start replacing all
those magic numbers with human readable names lile EF['IMSI'] instead of
['3F00', '7F20', '6F07'].

sysmo-usim-sjs1 requires P2 to be set to 0x0C (request FCI) when
using the USIM application commands. The FCI is not used by pysim
anyway and might even cause problems with other cards.
This commit adds a pair of get/set methods to the SimCardCommands
class in order to set a default for the selection control
parameters (P1, P2). (Similar to the set/get methods for the class
byte)
The SysmoUSIMSJS1 class now calls the setter method for the
selection control parameters inside of its constructuor and sets
the selection control parameter default to "000C". This way we
can be sure that we only change the behaviour for sysmo-usim-sjs1
and do not break support for any other cards.
