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).

Based on the paragraph from PKCS#11 MECHANISMS V2.30: 6.3.1 EC Signatures:
If the length of the hash value is larger than the bit length of n, only
the leftmost bits of the hash up to the length of n will be used. Any
truncation is done by the token.
This is affecting NIST PIV Test cards with non-hashed mechanisms.
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.
Limit the number of cases when applicated re-selection of application DF to strict minimum.
I.e. only when pkcs11 login session is not locked and private key PKCS#15 object do not
contain the 'path' attribute.
for some cards to prepare security environment for the PSO operation
card driver may need the value of 'algRef' attribut of tokenInfo.supportedAlgorithm.

emulated cards. True PKCS#15 cards with EC
will need additional changes.
Main changes are in framework-pkcs15.c, mechanism.c,
padding.c, pkcs15-algo.c and pkcs15-sec.c
where switch statements for key type, and testing
of flags was modified to make it easier to add
additional key types in the future.
The code was tested using RSA and ECDSA using a PIV card
from pkcs11-tool, OpenSSL and Thunderbird with
modifications to NSS-3.12.7 to get ECDSA to sign e-mail.
Only named curves are supported for ECDSA, ECDH is still
needed. pkcs11-tool has only minimal changes need to work
with the -O option to list EC keys.
One additional line was added to pkcs15-sec.c which
should get GOSTR sign to work.
libp11 and engine do not yet have EC support.

void sc_mem_clear(void *ptr, size_t len);
to clear a memory buffer. If OpenSSL is used this function
is a wrapper for OPENSSL_cleanse, otherwise memset is currenlty used.
Use this function to clear memory buffers with sensitive content.
