onomondo-ipa has a built-in IoT eUICC emulation. This means that we have to deal with two different EUICCInfo2 formats, which requires additional logic in ipa_es10b_get_euicc_info_free to free the allocated structs correctly. Since it is not immediately obvious how the logic works, let's add some explanary comments to make it obvious.
scard: add comment about memory-leak in libpcsclite
As it seems, SCardReleaseContext does not free all of the memory allocated by SCardEstablishContext. The probem has no real-world impact, but still showas up in valgrind. Let's add a comment so that we do not forget what causes the leak.
