c24538518c ThresholdMethod::TiledSauvola -> ThresholdMethod::Sauvola 
The fact that this method uses tiles is implementation detail. It does not change the result compared to Sauvola without tiles. The use of tiles minimize memory consumption.

f06b2c7c8d [capi] Restore some of wrongly removed apis. 
Removed C++ APIs are not restored.
Additionally remove unused C++ typedefs which were in removed C++ functions.
If you still need them, use C++ API instead.

bee90f7835 [capi] Remove unused functions. 
Those functions were undef ifdef for C++ mode. Since in C++ mode noone uses them, they can be safely removed.

52f5e5b8fb Restore building of C API. Simplify. 
1. Delete useless ifdefs.
2. Move C++ includes into source file. C code does not care about any C++ headers.
3. Replace TESS_CAPI_INCLUDE_BASEAPI with simple __cplusplus macro.
4. In capi.cpp remove enclosing namespace tesseract, so symbols have their according decls back.

In capi.cpp we
- put capi.h after all C++ headers, so we can remove some typedefs later,
- put using namespace tesseract between them, so C++ symbols are visible to functions in the file without namespace.

c86325e2f7 Use TESS_API for every public symbol. Public symbol is exported from the library. This also applies to unit test and training symbols. Users will be limited to public api, but set of exported symbols will be wider still. 
Remove TESS_LOCAL.
Fix several symbol issues that made visible with these changes.

All build systems must set -fvisibility-hidden for *nix systems.
