The pySim-smpp2sim.py program exposes two interfaces:
* SMPP server-side port, so external programs can rx/tx SMS
* APDU interface towards the SIM card
It therefore emulates the SMSC, Core Network, RAND and UE parts
that would normally be encountered in an OTA setup.

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.

This implements the first parts of the "GlobalPlatform Remote
Application Management over HTTP Card Specification v2.3 - Amendment B,
Versoin 1.2". Specifically, this patch covers the TLV definitions for
the OTA message used for HTTPS session triggering.
This also adds some more unit test coverage to pySim.cat, based on
real-world data that was captured nested inside the HTTPS Administration
session triggering parameters.

This fixes commit cdf661b24c
"pySim.tlv.COMPR_TLV_IE: Patch comprehension bit if derived class misses it"
where we introduce a comprehension-TLV specific derived metaclass, which forgets
to pass the kwargs through to the parent metaclass.
Change-Id: If65a8169bcf91bb2f943d0316f1140e07f0b8b8e
our implementation currently assumes that all derived classes are
created with a tag value that has the comprehension bit set.

Something like "this._.total_len-1" only works during decode. Let's
use GreedyBytes instead, working for encode and decode.

The human representation of a PLMN is usually MCC-MNC like 262-01
or 262-001. Let's add a PlmnAdapter for use within construct, so we
can properly decode that.

This adds deciding for the bulk of the TLV objects used in the
ETSI CAT (Card Application Toolkit) and 3GPP USAT (USIM Application
Toolkit) systems.
This patch just adds the definitions, but doesn't use them anywhere yet.

We had a mixture of tab and 4space based indenting, which is a bad
idea. 4space is the standard in python, so convert all our code to
that. The result unfortuantely still shoed even more inconsistencies,
so I've decided to run autopep8 on the entire code base.

This introduces a new TLV library that heavily builds upon python object
oriented concepts. Contrary to classic TLV parsers it doesn't focus on
the structure of Tag, Length and binary Value only, but it supports
actual decoding/interpretation of the value part into some kind of JSON
serializable dict. The latter can be achieved by imperative
encode/decode methods, or by using our existing declarative 'construct'
based approach.
The TLV library supports both BER-TLV and COMPREHENSION-TLV for both
nested and non-nested TLV definitions.
As an example we include TLV definitions for a number of CAT (Card
Application Toolkit) IEs.
