This file existed in earlier specs like Release 3.8.0, but was removed
in later revisions. Still, there are cards around implementing that
older spec, so let's add a decoder.

We want to use this class in an upcoming patch for DF_MCS support,
and in order to avoid cyclic imports, EF_UServiceTable must be moved.

cards can have multiple logical channels; each logical channel
has its own state of what is the current selected file + application.
Let's split the RuntimeState class into the global RuntimeState and the
per-lchan-specific RuntimeLchan class.
This code doesn't actually introduce any code that uses lchans other
than the basic logical channel (0), but just modifies the data model
to accomodate those in the future.

When using __str__ for a CardDF we would get "DF(DF.TELECOM)"
but when using it on CardADF we would get ADF(a0000000871002)"
instead of "ADF(ADF.USIM)". Let's fix that.
Change-Id: I5801a08bcc28cb222734af6d9ee835227f4fee69
As it is possible to select files relative to the currently selected
ADF, we should keep track of that.

We should first see if any of the files in the tree actually
require a service mapping before raising
ValueError('TODO: implement recursive service -> file mapping')

Service 126 relates to DF.5GS/EF.UAC_AIC. As we are deactivating that
file in the script, we should also disable the related EF.UST service.

In class SimCard, we specify the key reference for ADM1 as 0x04. in the
UsimCard class, which inherits from SimCard nothing is specified, even
though ETSI TS 102 221 specifies 0x0A as key reference. Lets set the
member in UsimCard accordingly to be closer to the spec.
Note: For the moment this is a cosmetic fix, it does not change the
behaviour since all card classes derived from UsimCard set the key
reference properly.
Change-Id: I96af395b1832f4462a6043cca3bb3812fddac612
ETSI TS 102 221, Table 9.3 specifies 0x0A as default key reference for
ADM1. Lets make sure pySim-shell uses this key-reference if the card is
a generic UICC.

The TLV IEs FILE SIZE and TOTAL FILE SIZE have a minimum length of 2
byte. Even when the length is in the single digit range two bytes must
be used. See also: ETSI TS 102 221, section 11.1.1.4.1 and 11.1.1.4.2

When updating files and records there are sometimes huge portions that
are just 0xff. Mostly this is at the end of a file or record that is not
completely used. Lets add a notation to tell PySim-shell how to fill
those sections.

When we run the exporter we also get an error summary at the end.
However, if walk() throws an eception this stops the exporter
immediately and we won't get the summpary. Lets catch exceptions from
walk as well so that we are able to end gracefully.
Change-Id: I3edc250ef2a84550c5b821a72e207e4d685790a5
The walk() method that we use to traverse the whole file system tree is
currently only able to execute action callbacks on EFs. Lets add a
mechanism that allows us to have a second callback that is executed when
we hit a DF or ADF.

The apdu command is used to communicate with the card on the lowest
possible level. Lets make it available even before a card profile (rs)
is avalable. This is especially useful when the card has no files on it,
in this situation pySim-shell will not be able to assign a profile to
the card at all. We can then use the apdu command to equip the card with
the most basic files and start over.

he method probe_file returns the decoded FCP after it managed to
successfully probe the file. Lets also return the encoded FCP string, as
it is needed by the caller.

The as_json parameter has been added as an additional parameter to the
export function. Lets use a dictionary here and put the parameter in it.
This makes it easier to add more options in the future

This information is mandatory for linear files as per TS 102 221 V15
section 11.1.1.4.3. This might not have been spotted earlier because
cards of type sysmoISIM-SJA2 accept creation without it as well.

Before this patch:
$ ./pySim-shell.py -p 0
Card reader initialization failed with an exception of type:

Card reader initialization failed with exception:

The DataObject is some weird / rarely used different code than the
normal TLV encoder/decoder. It has apparently so far only been used
for decoding, without testing the encoding side, resulting in related
bugs.
Let's fix those that I encountered today, and add a test case.

While the short ID of this file is 05, the actual file-id is 6f03.

This should avoid the following pylint error:
************* Module pySim.ts_31_102

These commands can be used to decode a user-provided hex-string,
instead of decoding the data read from the file. This is useful
for quickly manually decoding some values read from other locations,
such as e.g. copy+pasted from a eSIM profile in ASN.1 value notation.

The OPL has 7 bytes "LAI" as the LAI actually contains a LAC
range (so two more bytes for the end of the 16bit range).
Change-Id: I74bcf10b0a8977af0f2844044a812c5780af1706
range(0,7) in python is 0..6, and not 0..7, so we need range(0.8)
to produce the desired range covering all bits of a byte.
This resulted in services 8,16,24,... not being displayed in
the decoded output of EF.UST / EF.IST.

The SFI TLV contanins not the raw SFI, but it contains the SFI
shifted to left by 3 bits (for some strange reason). So let's
un-shift it.
