It's not necessary to initialize the vector with 0,
because the initial values are read from file.
Fix also an assertion when trying to read an empty file.

There exist standard macro definitions for the printf format specifiers.
MS Visual Studio does not support that standard (at least not in older
versions), so local definitions are needed there.

Both functions simply call malloc, free.
Remove also unneeded null pointer checks and use calloc where possible.

The code in ccutil/hashfn.h was needed for some old compilers. Now that we support MSVC >= 2010 and compilers that has good support for C++11, we can drop this code.
As a result of this file removal, we now use:
std::unordered_map
std::unordered_set
std::unique_ptr
directly in the codebase with '#include' for the needed headers.
This fixes a compiler warning from clang:

The compare method is called very often, so even small improvements
are important.
The new code avoids one comparison in each loop iteration.
This results in smaller code (60 bytes for x86_64, gcc).

POSIX provides portable data types for signed and unsigned integer values
of different size.
This patch maps those POSIX data types to the Tesseract specific types.
In a next step, the Tesseract data types can be eliminated by replacing
them with the POSIX data types.
