When sc_lock obtains a reader lock this function is called
If the card was reset the PIV AID is seletcted and logged_in is reset.
This is need for some PIV cards where the default AID is not the PIV AID
and some other process has reset the card.
closes#842
Add card_reader_lock_obtained function to sc_card_operations
During sc_lock, if card->reader->ops->lock is called, card->ops->card_reader_lock_obtained will be called.
If PCSC is being used as the reader driver, this occures just after pcsc_lock has done a SCardBeginTransaction
and our process has exclusive control over the card. The card driver can then determine if the state of the
card has changed, and take action to get the card into an acceptable state.
If card->reader->ops->lock returns SC_ERROR_CARD_RESET, indicating some other process has interefered
with the state of the card. was_reset=1 is passed to card->ops->card_reader_lock_obtained.
Some examples of actions that could be done by the card driver is to select the AID and reset logged_in.
Currently the card driver is not notified. So no default card_reader_lock_obtained is defined in iso7816.c
After card reset detected, run SM open under new transaction
Before trying to reestablish SM session or onte code that may
need to use a transaction, get the transaction that will be
used by the caller od sc_lock.

PIN cache is not updated when PIN is verified using the PIN value from cache.
That's the case of validating PIN in 'revalidate' context.
Few source format fixes included
closes#805
A sleep(1) is added after SCARD_W_CARD_RESET as done in other parts of reader-pcsc.c
Extra debugging messages are output.
SCard routines return "LONG" which may be different then "long" on some systems
were "LONG" is 32 bits and "long" is 64 bits.
Make sure printf format of 0x%08lx has a matching "long" input variable.
This closes#816
Not all PIV cards follow the NIST 800-73-3 standard. This commit is designed to address some
of the issues. OpenSC developers don't have access to all the different versions of devices
or access to release notes for the devices to see when a bug was introduced and when it is fixed.
To make OpenSC code changes easier, the code is divided into four sections:
(1) Identify the card/token as best possible by looking at the "Historical bytes" in the ATR.
For the Yubico devices read their version number and log it via sc_debug.
(2) Define the card_issues CI_* defines in card-piv.c. There are 8 of them at the moment.
See below.
(3) based on the card->type and possibly Yubico version set the priv->card_issues flags that
apply to current card or device.
(4) Implement in the code changes needed for each issue.
Other issues can be added. As more info is obtained (3) can be updated using the version
number as needed.
The card issues are:
CI_VERIFY_630X - VERIFY "tries left" returns 630X rather then 63CX
CI_VERIFY_LC0_FAIL - VERIFY Lc=0 never returns 90 00 if PIN not needed. Will also test after
first PIN verify if protected object can be used instead
CI_CANT_USE_GETDATA_FOR_STATE - No object to test verification in place of VERIFY Lc=0
CI_LEAKS_FILE_NOT_FOUND - GET DATA of empty object returns 6A 82 even if PIN not verified
CI_OTHER_AID_LOSE_STATE - Other drivers match routines may reset our security state and lose AID
CI_NFC_EXPOSE_TOO_MUCH - PIN, crypto and objects exposed over NFS in violation of 800-73-3
CI_NO_RSA2048 - does not have RSA 2048
CI_NO_EC384 - does not have EC 384
The piv_card_match and piv_init interactions were cleaned up.
Changes to be committed:
modified: card-piv.c
modified: cards.h
- IAS/ECC has the category indicator byte in EF.ATR, which is a
violation of ISO 7816-4, where it is only allowed in the historical
bytes of ATR. Removing the IAS/ECC specific modification of EF.ATR
allows reading ISO complient EF.ATR again.
- IAS/ECC parsing should still be successfull. We now always try to
check for ISO7816_TAG_II_STATUS_SW ignoring the category indicator
byte
introduced paramter to signal back the login state
- used for the pin command SC_PIN_CMD_GET_INFO
- implemented in accordance to ISO 7816-4; all other implementations
are currently set to an unknown login state
implemented and exporeted sc_pkcs15_get_pin_info
use sc_pkcs15_get_pin_info in C_GetTokenInfo
C_GetSessionInfo: Check whether a logout was done

`sm_incr_ssc` performed an out of bounds write when `ssc` is bigger than
255. The local variable `ii` needs to be decremented instead of
incremented in the `for`-loop.
This was introduced in d30cd83a, wheras The previous implementation did
actually decrement `ii`, see d30cd83ad4
Fixes https://github.com/OpenSC/OpenSC/issues/785

Unnecessarily strict regex was failing for some unknown reason on OS X. Easier to just relax the regex than understand what's wrong (and then relax the regex).
