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).

OpenSSL-1.1.0 was released 8/25/2016
OpenSSL-1.1.0a was released 9/22/2016

Changes to allow the OpenSC code base to work with OpenSSL versions from
0.9.7 to 1.1.0 with few changes.
This is an update and rebased version of my prep-openssl-1.1.0-pre6 branch.
No attempt was made to back port any OpenSSL features. These changes
just allow an updated OpenSC code base to use what is in the various OpenSSL
releases.
A new header libopensc/sc-ossl-compat.h contains extra defines
to reduce the need for so many #if OPENSSL_VERSION_NUMBER statements
in the source code.
The OpenSC source can now use the OpenSSL 1.1 API. The libopensc/sc-ossl-compat.h
has defines for the new API for use with older versions of OpenSSL.
sc-ossl-compat.h is included by libopensc/internal.h so all OpenSC
library routines can take advantage of it. For the tools, which do not use
libopensc/internal.h, libopensc/sc-ossl-compat.h is included by the tools.
The OpenSC source has been modified to use OpenSSL functions to access
hidden structures, such X509, BIGNUM, EVP_CIPHER_CTX, and use XXX_new
functions to allocate structures which must use pointer such as
BIGNUM and EVP_CIPHER_CTX.
For backward compatability sc-ossl-compat.h now defines inline routines
to emulate the RSA and DSA access routines in OpenSSL-1.1.0. Thus
the same OpenSC source code can be used with openSSL versions from
0.9.7 to 1.1.0.
Inline routines were chosen, because using macros does not work on all platforms.
Having OpenSC versions of these routines in libopensc would be a posibility,
but they are only used for older version of OpenSSL, and could be removed in
the future.

Removed cmap_record in sc_pkcs15_prkey_info (not used by any driver nor code)
Remove cardcf specific code (cardcf neutralized by CP_CACHE_MODE_NO_CACHE and it maintened by the Base CSP/KSP, not the minidriver)
Add conversion code for Windows GUID / OpenSC self computed GUID
In OpenSC the EC field_length is the number of bits in the field.
Most curves have a field_length which is a multiple of 8 bits
but there are many that are not.
The X and Y points and privateD are stored in octetstrings
so there may need to be an extra byte in the octetstring.
An OpenSSL BIGNUM will drop leading zero bytes, so its size can not be used
to determine the field_length.
fix#440fix#433
existing 'guid' obejct's data replaced by the one in private-key info
New CMAP record data used by pkcs15init emulator for the cards that have
the MD specific on-card data
Coverity: Missing break in switch (MISSING_BREAK)
"A break statement was missing. The case SC_PKCS15_TYPE_PRKEY_EC was then
managed as a SC_PKCS15_TYPE_PRKEY_DSA" (Ludovic Rousseau)
"the break here has no sense, because LOG_TEST_RET will always return SC_ERROR_NOT_SUPPORTED before"
(Frank Morgner https://github.com/OpenSC/OpenSC/pull/85)
'break' is kept to satisfy coverity.
"The encoding of {public,private}GOSTR3410Key uses tag [CONTEXT 3] which is reserved for KEAKey.
Caused by the fact, that the specifications (pkcs15,iso) don't define a encoding for GOST,
the genericKey encoding [CONTEXT 4] from iso-7816 should be used." (Andre)
when freeing key object, do not throw an error if supplied key pointer is NULL;
sc_pkcs15_free_prkey() procedure should not free the supplied key pointer,
the body of this procedure is replaced by body of sc_pkcs15_erase_prkey().
staitc sc_pkcs15_erase_prkey() is not more used.
Decoding/encoding of the 'algReference' attribute from the 'CommonKeyAttributes'.
Use macros for the size of the asn1_entry tables.
Use short call form for debug messages.
Procedure to deduce from certificate the attributes of private key PKCS#15 object.
Procedure to convert the pkcs15 private key to EVP_PKEY type key.
Coding style issues.
pkcs15-wrap.c can be removed. Clarified/changed the meaning of "insecure" flag to pkcs15-init tool,
which will be needed to explicitly enforce the creation of a key which does not require a PIN.

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.

From http://en.wikipedia.org/wiki/Malloc#Casting_and_type_safety
" Casting and type safety
malloc returns a void pointer (void *), which indicates that it is a
pointer to a region of unknown data type. One may "cast" (see type
conversion) this pointer to a specific type, as in
int *ptr = (int*)malloc(10 * sizeof (int));
When using C, this is considered bad practice; it is redundant under the
C standard. Moreover, putting in a cast may mask failure to include the
header stdlib.h, in which the prototype for malloc is found. In the
absence of a prototype for malloc, the C compiler will assume that
malloc returns an int, and will issue a warning in a context such as the
above, provided the error is not masked by a cast. On certain
architectures and data models (such as LP64 on 64 bit systems, where
long and pointers are 64 bit and int is 32 bit), this error can actually
result in undefined behavior, as the implicitly declared malloc returns
a 32 bit value whereas the actually defined function returns a 64 bit
value. Depending on calling conventions and memory layout, this may
result in stack smashing.
The returned pointer need not be explicitly cast to a more specific
pointer type, since ANSI C defines an implicit conversion between the
void pointer type and other pointers to objects. An explicit cast of
malloc's return value is sometimes performed because malloc originally
returned a char *, but this cast is unnecessary in standard C
code.[4][5] Omitting the cast, however, creates an incompatibility with
C++, which does require it.
The lack of a specific pointer type returned from malloc is type-unsafe
behaviour: malloc allocates based on byte count but not on type. This
distinguishes it from the C++ new operator that returns a pointer whose
type relies on the operand. (see C Type Safety). "

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.

building PC/SC, OpenCT or USBToken support,
use ifdef's directly in source.
- Because of above, add HAVE_PCSCLITE for winconfig.h
- Remove unnecessary includes for log.h, opensc.h and
errors.h in libopensc sources, they're already taken
care by internal.h.
