c7c48718ba Get rid of [now] superfluous HexAdapter
With the introduction of using osmocom.construct.{Bytes,GreedyBytes}
in Change-Id I1c8df6350c68aa408ec96ff6cd1e405ceb1a4fbb we don't have a
need for wrapping each instance of Bytes or GreedyBytes into a
HexAdapter anymore.  The osmocom.construct.{Bytes,GreedyBytes} will
automatically perform the related hex-string-to-bytes conversion if
needed - and during printing we have osmocom.utils.JsonEncoder that
makes sure to convert any bytes type to a hex-string.

15140aae44 global_platform: add new command "install_cap"
Installing JAVA-card applets from a CAP file is a multi step process, which is
difficult when done manually. Fortunately it is easy to automate the process,
so let's add a dedicated command for that.

712946eddb javacard: add parser for JAVA-card CAP file format
To install JAVA-card applets we need to be able to extract the executeable
loadfile and the AIDs of the applet and the loadfile. This patch adds the
parser and related unittests.

852eff54df pySim/transport add support for T=1 protocol and fix APDU/TPDU layer conflicts
ETSI TS 102 221, section 7.3 specifies that UICCs (and eUICCs) may support two
different transport protocols: T=0 or T=1 or both. The spec also says that the
terminal must support both protocols.

This patch adds the necessary functionality to support the T=1 protocol
alongside the T=0 protocol. However, this also means that we have to sharpen
the lines between APDUs and TPDUs.

As this patch also touches the low level interface to readers it was also
manually tested with a classic serial reader. Calypso and AT command readers
were not tested.

93c89856c8 utils: move enc_msisdn and dec_msisdn to legacy/utils.py
We now have a construct based encoder/decoder for the record content
of EF.MSISDN. This means that we do not need the functions enc_msisdn
and dec_msisdn in the non-legacy code anymore. We can now move both
to legacy/utils.py.

efddffe015 filesystem: pass total_len to construct of when encoding file contents
In our construct models we frequently use a context parameter "total_len",
we also pass this parameter to construct when we decode files, but we
do not pass it when we generate files. This is a problem, because when
total_len is used in the construct model, this parameter must be known
also when decoding the file.

Let's make sure that the total_len is properly determined and and passed
to construct (via pyosmocom).

a3962b2076 Migrate over to using pyosmocom
We're creating a 'pyosmocom' pypi module which contains a number of core
Osmocom libraries / interfaces that are not specific to SIM card stuff
contained here.

The main modules moved in this initial step are pySim.tlv, pySim.utils
and pySim.construct. utils is split, not all of the contents is
unrelated to SIM Cards.  The other two are moved completely.

e0241037e7 tests: move unittests into a sub directory
We currently mix the unit-tests with the shell script based integration
tests. Let's put them into a dedicated sub directory.
