Steve Ross abdbb9d8c0 Enable CoolKey driver to handle 2048-bit keys.
For a problem description, see <https://github.com/OpenSC/OpenSC/issues/1524>.
In a nutshell, for a card with the CoolKey applet and 2048-bit keys,
the command
	pkcs11-tool --test --login
fails to complete all of its tests.

This commit consists of a patch from @dengert.

To avoid triggering an error when the data exceeds 255 bytes, this commit
limits the amount of the payload sent to the CoolKey applet on the card based
on the maximum amount of data that the card can receive, and overhead bytes
(namely, a header and nonce) that accompany the payload.

With this change, the command
	pkcs11-tool --test --login
succeeds.

Frank Morgner 410cdf0dcc refactored sc_get_challenge
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

Maciej S. Szmigiero 62cbda6cd9 Fix log messages format and parameter issues flagged by GCC
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).
