- rename 'keytype' in some OpenPGP-specific types to 'key_id'
because they key ID was what the field was used for
- introduce field 'algorithm' in the structures above
to indicate the key's algorithm: RSA, ...
- define constant SC_OPENPGP_KEYALGO_RSA and use it
- rename constants SC_OPENPGP_KEYFORMAT_* to SC_OPENPGP_KEYFORMAT_RSA_*
because they are RSA specific
List additional algorithms & attributes as supported only when the card
supports changing the algorithms attributes DOs and exposes this by having
the EXT_CAP_ALG_ATTR_CHANGEABLE capability set.
Using different algorithms and attributes requires changing the algorithm
attributes DOs. If that is not supported - as indicated by a missing
EXT_CAP_ALG_ATTR_CHANGEABLE capability - then only those algorithms
described by the current algorithms attributes DOs' contents can be used.
In addition simplify setting the flags.
* use variables if they are already there
* be a bit more explicit in logging
* more consistent tag format: %04X
* cleanup flag setting for _sc_card_add_rsa_alg()
As most of the drivers do not modify these, we can mark them as const.
Two drivers that we cannot convert are dnie and masktech.

... for "standard" OpenPGP cards.
This gives more detailed information to the user on the detailed specs
the card adheres to.
In addition it fixes a long-standing annoyance that every standard 2.x
card matching the v2.0 ATR was announced as CryptoStick 1.2.
This ATR is not only used in the CryptoStick 1.2, but also also in
ZeitControl cards as well as NitroKeys, ...
To help debugging,
- replace plain return's after LOG_FUNC_CALLED()
has been called with LOG_FUNC_RETURN()
- use LOG_FUNC_CALLED() & LOG_FUNC_RETURN() pairs more often
* new function sc_compacttlv_find_tag()
Add function sc_compacttlv_find_tag() to search for a tag in a
compact-TLV structure.
* OpenPGP: use sc_compacttlv_find_tag()
While doing so, fix a typo affection OpenPGP v3.x cards
Instead of simply searching for a trigger byte with the risk of
getting garbage, correctly parse historical bytes from ATR as well
as the "historical bytes" DO as compact TLV structures.
In addition
- prepare for additional data used in OpenPGP cards 3.x
- ignore [per the spec] chaining capability fo OpenPGP cards 1.x
Let sc_get_challenge() do sc_lock() and loop through the card driver's
get_challenge() until enough bytes were collected. The card driver's
get_challenge() now returns the number of bytes collected (less or equal
than requested) or an error code.
- Allow more code re-use.
- PIV driver now uses ASN.1 parser for reading the random bytes
We can't check for `tag == SC_ASN1_TAG_EOC` directly, because this
would also be true for a tag of 0x80 (with `class ==
SC_ASN1_CLASS_CONSTRUCTED`). So what we do is we check for the output
buffer to be NULL!

The maximum length for sending and receiving data can now be found in DO
7F66. For now, we just use the default values for short/extended length
capabiliites.
PKI-Applets may not be active if the card has been reset or unpowered.
The SELECT command used to activate the applet, is identical to the one
used during card matching or initialization.
