Harald Welte 3f3fd1a841 add SAIP template handling + v3.1 definitions
This adds classes for describing profile templates as well
as derived classes defining the profile templates of the
"Profile Interoperability Technical Specification", specifically
it's "ANNEX A (Normative): File Structure Templates Definition"

We need a machine-readable definition of those templates, so
we can fully interpret an unprotected profile package (UPP),
as the UPP usually only contains the increment/difference to
a given teplate.

Harald Welte 263e3094ba requirements.txt: Switch to osmocom fork of asn1tools
This is sadly required as the Interoperable Profile format must process
elements of an ASN.1 sequence in order, which doesn't work if the parser
puts the elements in a python dict.

The osmocom fork of asn1tools hence uses OrderedDict to work around
this problem.

Harald Welte 1f7a9bd5b4 TLV: Add DGI encoding of "GP Scripting Language Annex B"
The DGI encoding is specified in Annex B of the
"GlobalPlatform Systems Scripting Language Specification v1.1.0"

which is an "archived" specification that is no longer published
by GlobalPlatform, despite it being referenced from the GlobalPlatform
Card Specification v2.3, which is the basis of the GSMA eSIM
specifications.

For some reason it was the belief of the specification authors that
yet another format of TLV encoding is needed, in addition to the BER-TLV
and COMPREHENSION-TLV used by the very same specifications.

The encoding of the tag is not really specified anywhere, but I've only
seen 16-bit examples.  The encoding of the length is specified and
implemented here accordingly.

Harald Welte 5bbb144a31 Initial proof-of-concept SM-DP+ for GSMA consumer eSIM RSP
This commit introduces

* the osmo-smdpp.py program implementing the main procedures and the
  HTTP/REST based ES9+
* python modules for ES8+ and non-volatile RSP Session State storage
* the ASN.1 source files required to parse/encode RSP
* 3GPP test certificates from SGP.26
* an unsigned profile package (UPP) of a SAIP v2.3 TS48 test profile

As I couldn't get the 'Klein' tls support to work, the SM-DP+ code
currently does not support HTTPS/TLS but plan HTTP, so you either have
to modify your LPA to use HTTP instead of HTTPS, or put a TLS proxy in
front.

I have successfully installed an eSIM profile on a test eUICC that
contains certificate/key data within the test CI defined in GSMA SGP.26

Harald Welte dffe7af578 Fix enumeration of GlobbalPlatformISDR during card_init()
We used __subclasses__(), but this only returns the immediate
subclasses and not all further/nested subclasses.  Instead, we must
use the pySim.utils.all_subclasses() function to really get all of them.

The hack to use the method signature of the constructor to determine if
it's an intermediate class didn't work, as even GlobbalPlatformISDR
has a optional argument for non-default AIDs.  So let's introduce an
explicit class attribute for that purpose.

While we do have the _test_de_encode data driven tests for file
definitions, we don't yet have something similar for derived classes of
BER_TLV_IE. This means that TLVs used outside of the filesystem context
(for example, decoding the SELECT/STATUS response, but also eUICC and
other stuff) do not yet have test coverage.

This commit just adds the related test code, but no test data yet.

Harald Welte a9b21bdb1f tlv: Fix from_dict() symmetry
the to_dict() method generates a {class_name: value} dictionary,
for both the nested and non-nested case.  However, before this patch,
the from_dict() method expects a plain list of child IE dicts
in the nested case.  This is illogical.

Let's make sure from_dict always expectes a {class_name: value} dict
for both nested and non-nested situations.
