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).

ludovic.rousseau f47416d60e Do not cast the return value of malloc(3) and calloc(3)
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). "
