CL_PROGRAM_NUM_DEVICES expects a cl_uint.
Passing size_t results in a wrong value for numDevices on hosts where

CL_CONTEXT_NUM_DEVICES expects a cl_uint.
Passing size_t results in a wrong value for numDevices on hosts where
sizeof(cl_uint) != sizeof(size_t). This results in errors like these:
Tesseract Open Source OCR Engine v3.05.00dev with Leptonica
OpenCL error code is -44 at when clCreateKernel kernel_HistogramRectAllChannels .
OpenCL error code is -44 at when clCreateKernel kernel_HistogramRectAllChannelsReduction .
OpenCL error code is -48 at when clSetKernelArg imageBuffer .

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).

Commit b1f03cb697 added a call of function
FreeFeatureSet to fix a memory leak, but introduced a new bug because the
local variable FloatFeatures was not always assigned a value.
Now FloatFeatures is always assigned a value, and we only need a single
place where FreeFeatureSet is called.

This is caused by a buggy implementation which increases the value of num
instead of *num.

It is only used locally in opencl/openclwrapper.cpp.
For all other files which include openclwrapper.h, the compiler

Both arrays are only used in openclwrapper.cpp, so move them into that
file.
The first element of both arrays was unused. Remove it and fix the code
which reads the array elements accordingly. Sort this code, too.
These changes reduce the code size a little bit:

openclwrapper calls function TIFFReadRGBAImageOriented which is provided
by libtiff, so add that library to OPENCL_LIBS.
This fixes a linker error (unresolved symbol) when opencl is enabled.

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.

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.
