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.

Calling TessBaseAPI::Clear() which calls TessBaseAPI::ClearResults()
which calls SavePixForCrash(0, NULL) is needed to release objects
allocated in global_crash_pixes.

Avoid dynamic memory allocation for the static variable 'cache'.
Now the destructor for that variable is called automatically
when Tesseract terminates and releases all associated memory.

When exit() is called from ParseArgs(), no destructors are executed
for the auto variables vars_vec and vars_values.
Making both variables static fixes the memory leaks, because now the
destructors are always executed.

A haystack which is shorter than the needle resulted in negative value
for length_haystack which was forced to a very large unsigned value.
The resulting buffer overflow while reading the haystack would crash
text2image when it was called with a short font name.
