* Add OPENMP_CXXFLAGS for ccmain.
* Replace OPENMP_CFLAGS by OPENMP_CXXFLAGS.
* Always use _OPENMP for conditional compilation.
* Remove OPENMP as there is already _OPENMP.
* Include omp.h conditionally.

See issue #424.
The existing C API for TessBaseAPIDetectOS requires a C caller to successfully allocate struct OSResults which is actually a C++ class. Generally it won't
be possible for a regular C compiler to do this properly.
It's also assumed that most API level users of Tesseract are only interested in Tesseract's best guess as to script and orientation, not the individual values for all possible scripts.
This introduces a new API with a better name that is more closely aligned with the output of 'tesseract -psm 0'. Both tesseract -psm 0 and this API now share the same code in baseapi.cpp.

It was introduced recently in commit f24ef67d, so there is no need
to support the old variant for compatibility reasons.

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

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.

It conflicts with a previous 'class' declaration for ETEXT_DESC:

The previous commit added a dependency on tiffio.h, so enable the new
code only if that file is available.
The code which conditionally defines HAVE_TIFFIO_H was already there
although that macro was unused up to now.

Showing them in a window (default) is not acceptable for a console
application like Tesseract which must be able to work in batch mode.

In Tesseract's coordinate system, width is just right - left, cf. slide #2 of

It is common practice for command line programs to print
user requested information on stdout.
This seems to be reasonable for Tesseract, too.

Most command line programs print the version to stdout.
This seams to be reasonable for Tesseract, too.
Now a shell statement like "VERSION=$(tesseract --version)" works
without I/O redirection.

Takes advantage of inheritance and dir="ltr" default to:
- only generate paragraph dirs which are not ltr
- only generate word dirs which don't match enclosing paragraph
Tested against LTR, RTL, and mixed direction files. Files for the
latter two cases are in a separate commit on the ltr-test-files branch.
This fixes the duplicate line IDs caused by inserting height information
into the middle of the ID and it moves the line height info into
the title attribute like everything else, rather than using non-standard
HTML attributes (which won't validate).
This change may break consumers of the HTML output, but 3.04 has only
been in the wild for 6 months and the current HTML is invalid, so I
believe the benefit outweighs the cost for the fix.
