Harald Welte b582c3c7ea euicc: Fix TLV IE definitions for SetNickname{Req,Resp}
The metaclass uese the 'nested' attribute, while the existing code
accidentially used the 'children' attribute.  The latter is used
by instances for actual child classes, while the Class/nested
attribute is for the list of classes whose instancse could be potential
children.

Harald Welte c20d442695 euicc: Fix encoding of Lc value in STORE DATA
The length value "of course" is a hex value, don't use %02u but %02x

This fixes any eUICC command with a Lc > 10 bytes.

Harald Welte 0f7d48ed69 tlv: Fix encoding of zero-valued TLVs
If a TLV was elementary (no nested IEs), and it had only a single
integer content whose value is 0, we erroneously encoded that as
zero-length TLV (len=0, no value part):

>>> rf = pySim.euicc.RefreshFlag(decoded=0);
>>> rf.to_bytes()
b''
>>> rf.to_tlv()
b'\x81\x00'

After this change it is correct:

>>> rf = pySim.euicc.RefreshFlag(decoded=0);
>>> rf.to_bytes()
b'\x00'
>>> rf.to_tlv()
b'\x81\x01\x00'

Harald Welte 4e02436dba perform multiple GET RESPONSE cycles if more data is available
So far we implemented only one round of "Send the APDU, get SW=61xx,
call GET RESPONSE".  This permitted us to receive only data up to 256
bytes.

Let's extend that to doing multiple rounds, concatenating the result.
This allows us to obtain arbitrary-length data from the card.

See Annex C.1 of ETSI TS 102 221 for examples showing multiple 61xx
iterations.

We've already had the 'open_channel' and 'close_channel' commands,

the user can determine which of the (previously opened) logical channels
shall be used by pySim-shell.

Harald Welte 2d5959bf47 ts_102_221: Remove CardProfileUICCSIM
This profile has always been a hack/work-around for the situation that
a classic GSM SIM is not a UICC, and we didn't yet have the concept of
CardProfileAddons yet, so there was no way to probe and add something
to an UICC which was not an application with its own AID/ADF.

Since now we have CardProfileAddons (including one for GSM SIM),
and pySim-trace (the other user of CardProfileUICCSIM) has also switched
over to using CardProfileUICC + addons, we can remove this work-around.

Harald Welte 323a35043f Introduce concept of CardProfileAddon
We have a strict "one CardProfile per card" rule.  For a modern UICC
without legacy SIM support, that works great, as all applications
have AID and ADF and can hence be enumerated/detected that way.

However, in reality there are mostly UICC that have legacy SIM, GSM-R
or even CDMA support, all of which are not proper UICC applications
for historical reasons.

So instead of having hard-coded hacks in various places, let's introduce
the new concept of a CardProfileAddon.  Every profile can have any
number of those.  When building up the RuntimeState, we iterate over the
CardProfile addons, and probe which of those are actually on the card.
For those discovered, we add their files to the filesystem hierarchy.

Harald Welte f8d2e2ba08 split pySim/legacy/{cards,utils} from pySim/{cards,utils}
There are some functions / classes which are only needed by the legacy
tools pySim-{read,prog}, bypassing our modern per-file transcoder
classes.  Let's move this code to the pySim/legacy sub-directory,
rendering pySim.legacy.* module names.

The long-term goal is to get rid of those and have all code use the
modern pySim/filesystem classes for reading/decoding/encoding/writing
any kind of data on cards.

Harald Welte 2352f2dcdd pySim/tlv.py: Fix TLV_IE_Collection from_dict with nested collections
This is all quite complicated.  In general, the TLV_IE.to_dict() method
obviously is expected to return a dict (with key equal to the snake-case
name of the class, value to the decode IE value).  This single-entry
dict can then be passed back to the from_dict() method to build the
binary representation.

However, with a TLV_IE_Collection, any TLV_IE can occur any number of
times, so we need an array to represent it (dict would need unique key,
which doesn't exist in multiple instances of same TLV IE).  Hence, the
TLV_IE_Collection.to_dict() method actually returns a list of dicts,
rather than a dict itself.  Each dict in the list represents one TLV_IE.

When encoding such a TLV_IE_Collection back from the list-of-dicts, we
so far didn't handle this special case and tried to de-serialize with
a class-name-keyed dict, which doesn't work.

This patch fixes a regression in the aram_store_ref_ar_do pySim-shell
command which got introduced in Change-Id I3dd5204510e5c32ef1c4a999258d87cb3f1df8c8

While we're fixing it, add some additional comments to why things are
how they are.

The TLV_IE_Collection, just like the individual TLV classes, do
use their snake-style names when converting from binary to dict
using the to_dict() method.  It is inconsistent (and a bug) to
expect the CamelCase names during encoding (from_dict).  After all,
we want the output of to_dict() to be used as input to from_dict().

Harald Welte f4a01472bf pySim-shell: Support USIM specific methods/commands on unknown UICC
So far, if no known programmable card (like sysmoISIM) has been found,
we were using the SimCard base class.  However, once we detect an UICC,
we should have switched to the UsimCard class, as otherwise the various
methods called by USIM/ISIM specific commands don't exist and we get
weird 'SimCard' object has no attribute 'update_ust' execptions.

The entire auto-detection and the legacy SimCard / UsimCard classes
are showing the legacy of the code base and should probably be
re-architected.  However, let's fix the apparent bug for now.

Harald Welte 579ac3ec0e tlv: Fix IE.from_dict() method
The existing IE.from_dict() method *supposedly* accepts a dict as
input value, but it actually expects the raw decoded value, unless it is
a nested IE.  This is inconsistent in various ways, and results in a bug
visible at a higher layer, such as files like EF.{DOMAIN,IMPI,IMPU},
which are transparent files containing a single BER-TLV IE.

Decoding such files worked, but re-encoding them did not, due to the
fact that we'd pass a dict to the from_dict method, which then gets
assigned to self.decoded and further passed along to any later actual
encoder function like to_bytes or to_tlv.  In that instance, the dict
might be handed to a self._construct which has no idea how to process
the dict, as it expects the raw decoded value.
