Since "Add GCC format checking attributes to log functions" commit GCC
warns us about problems with format strings and their arguments provided
to OpenSC message logging functions.
This commit fixes all cases where GCC warned about incorrect format on
64-bit Linux, 32-bit and 64-bit mingw builds (with SM and OpenSSL enabled).
Well, almost all since on mingw GCC does not recognize "ll" size specifier
(present at least since Visual Studio 2005, also in mingw own CRT) so these
(few) warnings about it remain.
In most cases format size specifier for size_t type was missing (usually
size was left at default int level, with is different on 64-bit x86).
Some formats had too few / too many arguments.
In some cases pointers were printed as integers.
Some long variables were missing "l" prefix (especially with regard to %x
format).

This commit fixes most of warnings shown by GCC on 64-bit Linux, 32-bit and
64-bit mingw builds (with SM and OpenSSL enabled).
These warnings were mostly caused by missing casts.
In minidriver there was also a bit of unused variables and dead code.
Remaining warnings on mingw are mostly caused by GCC not recognizing on
this platform "ll" size specifier (present at least since
Visual Studio 2005, also in mingw own CRT) and "z" size specifier (this one
will be fixed in next commits).
There is also a warning about pointer truncation on Win64 when making
PKCS#11 object handle from pointer to this object.
This is a legitimate warning, since it could result in the same handles
being generated from different pointers and so from different objects.

As defined in BSI TR-03119 to issue SCardTransmit (with Uses
Pseudo-APDU) instead of SCardControl (with FEATURE_VERIFY_PIN_DIRECT).
It allows using a very basic PC/SC reader driver without special support
for PIN verification or modification (such as the default CCID driver on
Windows).
Also gets IFD vendor information via escape commands.
PC/SC's Get Uid command is now only triggered if enable_escape = true;
was set by the user to allow disabling wrapped commands on broken
readers (see https://github.com/OpenSC/OpenSC/issues/810)
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.

The special value still needs to be handled for commands that are issued
during card initialization. This especially concerns T=0 cards that need
to use iso_get_response.
fixes#533
regression of 85b79a3332
If the reader announces extended length support, but the card driver
leaves max_send_size/max_recv_size at `0`, max_send_size/max_recv_size
previously would have been overwritten with the reader's size though the
card might not have set SC_CARD_CAP_APDU_EXT. This commit fixes this
behavior.
Additionally card->max_send_size/max_recv_size is always initialized to
a value different from 0 after the card initialization. This removes the
need to check for this special value in all subsequent calls.
needed to store information about EC curve supported by card.
Primary usage is when importing/generating key to get know if particular curve is supported by card.
fixes a lot of warnings which pass a const buffer to the APDU's data
Note that a non-const data member is only required for sc_allocate_apdu
sc_free_apdu. They are currently used with an explicit typecast.
However, sc_allocate_apdu and sc_free_apdu both are not used once in the
entire project. One might also simply throw both functions away.
-- Both are thrown away. (VT)
Initiated by discussion in https://github.com/OpenSC/OpenSC/pull/134 .
SC_ERROR_MEMORY_FAILURE has to be used as a resulting code of the card related operations,
and not as result of the memory allocation problems.
New 'warning' category of SC_ERRORs introduced -- SC_WARNING_xx .
Error text and SC_ERROR associated with return codes 6300 and 6200 has been changed.
t457 (https://www.opensc-project.org/opensc/ticket/457)
For some cards that currently use the common iso-7816 operations
only SELECT with return of FCI/FCP can be applied.
In iso-7816 'select-file' handle, if 'SELECT without FCI' fails with error code 6A86,
then retry 'SELECT with FCI'. Other error code can be added.
Sorry for the 'coding style' noise.
Most smart cards currently have only 64K or 128K of EEPROM. This will give better errors earlier for people trying to import huge keyfiles with TrueCrypt.

add 'current_ef' and 'current_df' member to 'sc_card_cache'.
The main purpose of this is to reduce number of APDU transactions.
