579214c4d0 card_key_provider: remove method _verify_get_data from base class
The method _verify_get_data was intended to be used to verify the
user input before it further processed but ended up to be a simple
check that only checks the name of the key column very basically.

Unfortunately it is difficult to generalize the check code as the
concrete implementation of those checks is highly format dependent.
With the advent of eUICCs, we now have two data formats with
different lookup keys, so a static list with valid lookup keys is
also no longer up to the task.

After all it makes not much sense to keep this method, so let's
remove it.

(From the technical perspective, the key column is not limitied to
any specif field. In theory it would even be possible to use the KI
as lookup key as well, even though it would not make sense in
practice)

4a7651eb65 pySim-shell: re-organize Card Key Provider related options
As we plan to support other formats as data source for the Card Key
Provider soon, the more commandline options may be added and it makes
sense to group the Card Key Provider options in a dedicated group.

Let's also rename the option "--csv-column-key" to just "--column-key".
The column encryption is a generic concept and not CSV format specific.
(let's silently keep the "--csv-column-key" argument so maintain backward
compatibility)

01a6724153 pySim-shell: add command to manually query the Card Key Provider
The Card Key Provider is a built in mechanism of pySim-shell which
allows the user to read key material from a CSV file in order to
avoid having to lookup and enter the key material himself. The
lookup normally done by the pySim-shell commands automatically.

However, in some cases it may also be useful to be able to query the
CSV file manually in order to get certain fields displayed. Such a
command is in particular helpful to check and diagnose the CSV data
source.

e80f96cc3b card_key_provider: use case-insensitive field names
It is common in CSV files that the columns have uppercase names, so we
have adopted this scheme when we started using the card_key_provider.

This also means that the API of the card_key_provider_get() and
card_key_provider_get_field() function now implicitly requires
uppercase field names like 'ICCID', 'ADM1', etc.

Unfortunately this may be unreliable, so let's convert the field
names to uppercase as soon as we receive them. This makes the API
case-insensitive and gives us the assurance that all field names
we ever work with are in uppercase.

4550574e03 card_key_provider: separate and refactor CSV column encryption
The CardKeyProviderCsv class implements a column decryption scheme
where columns are protected using a transport key. The CSV files
are enrcypted using contrib/csv-encrypt-columns.py.

The current implementation has two main problems:

- The decryption code in CardKeyProviderCsv is not specific to CSV files.
  It could be re-used in other formats, for example to decrypt columns
  (fields) red from a database. So let's split the decryption code in a
  separate class.

- The encryption code in csv-encrypt-columns.py accesses methods and
  properties in CardKeyProviderCsv. Also having the coresponding
  encryption code somewhere out of tree may be confusing. Let's improve
  the design and put encryption and decryption functions in a single
  class. Let's also make sure the encryption/decryption is covered by
  unittests.

08565e8a98 pySim-shell: use log level INFO by default
The default log level of the PySimLogger is DEBUG by default. This is
to ensure that all messages are printed in an unconfigured setup.

However in pySim-Shell we care about configuring the logger, so let's
set the debug log level to INFO in startup. This will allow us to
turn debug messages on and off using the verbose switch.

94811ab585 pySim-shell: allow user friendly selection of the pin type
The CHV commands (verify_chv, enable_chv, disable_chv, unblock_chv)
provide a --pin-nr parameter.

The --pin-nr is a decimal parameter that specifies the pin type to be
used. The exact pin type numbers are specified in ETSI TS 102.221,
Table 9.3.

Unfortunately the --pin-nr parameter is not very intuitive to use, it
it requires the user to manually lookup the numeric value. The specs
list that value as hexadecimal, so the user also has to convert it
to decimal. To make this less complicated, let's also accept
hexadecimal numbers with the --pin-nr parameter.

However, this alone does not improve the user expierience much. Let's
also add a --pin-type parameter (similar to the --adm-type parameter
of the verify_adm command) to specifiy the pin type in a human
readable form.

f94f366cf9 runtime: check record/file size before write
When writing data to a transparent or linear fixed (record oriented)
and the data to write exceeds the record/file size, then the UICC will
respond with an error "6700: Checking errors - Wrong length"

In particular when the data is supplied as a JSON object and not as a
hex string, it may not be immediately obvious to the average user what
the problem actually is.

Let's check the record/file size before writing the data and raise an
exception in case the data excieeds the record/file size. Let's also
print an informative string message in case the data length is less
than the record/file size to make the user aware of unwritten bytes
at the end of a record/file.

4429e1cc70 pySim-shell: add a logger class to centralize logging
In many sub modules we still use print() to occassionally print status
messages or warnings. This technically does not hurt, but it is an unclean
solution which we should replace with something more mature.

Let's use python's built in logging framework to create a static logger
class that fits our needs. To maintain compatibility let's also make sure
that the logger class will behave like a normal print() statement when no
configuration parameters are supplied by the API user.

To illustrate how the approach can be used in sub-modules, this patch
replaces the print statements in runtime.py. The other print statements
will the be fixed in follow-up patches.

d838a95c2a edit_{binary,record}_decoded: Support hex-decode of bytes
We've created + used osmocom.utils.JsonEncoder as an encoder class
for json.{dump,dumps} for quite some time.  However, we missed to
use this decoder class from the edit_{binary,record}_decoded commands
in the pySim-shell VTY.

fbe6d02ce3 docs/saip-tool: fix ERROR: Unexpected indentation
According to [1], the literal block must be indented (and, like all
paragraphs, separated from the surrounding ones by blank lines).

[1] https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#literal-blocks

While at it, fix tabs-vs-spaces: use 2 spaces like in other places.

aace546900 filesystem: fix WARNING: Block quote ends without a blank line
Use the 'r' (raw) qualifier to avoid rendering '\n' as the actual
line break in the auto-generated documentation.
