94be4be4be ccutil/ambigs: Optimize tesseract::UnicharIdArrayUtils::compare 
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).

1274874e90 ccutil: Fix and simplify implementation of variadic macro 
The implementation for MS C did not pass the variable arguments to
tprintf.

The standard is supported since C99 / C++11, so one implementation
is sufficient.

eb00574c4a Remove conditional definition of off_t 
As pointed out by Stefan Weil, conditionally defining off_t using a
macro isn't a valid approach. off_t does not have a fixed size and is
used in ABI definitions (e.g. syscalls), so silently guessing its size
risks breaking the build. Additionally, all sane and modern platforms
will have off_t.

84920b92b3 Font and classifier output structure cleanup. 
Font recognition was poor, due to forcing a 1st and 2nd choice at
a character level, when the total score for the correct font is often
correct at the word level, so allowed the propagation of a full set
of fonts and scores to the word recognizer, which can now decide word
level fonts using the scores instead of simple votes.

Change precipitated a cleanup of output data structures for classifier
results, eliminating ScoredClass and INT_RESULT_STRUCT, with a few
extra elements going in UnicharRating, and using that wherever possible.
That added the extra complexity of 1-rating due to a flip between 0 is
good and 0 is bad for the internal classifier scores before they are
converted to rating and certainty.
