  Adding OpenType validation module. The code is based on the (unfinished) `otlayout' module but has been heavily modified to make it much more compact. * src/otvalid/*: New module. * include/freetype/ftotval.h, src/base/ftotval.c, include/freetype/internal/services/svotval.h: New files. * include/freetype/config/ftmodule.h: Add otv_module_class. * include/freetype/config/ftheader.h (FT_OPENTYPE_VALIDATE_H): New macro. * include/freetype/internal/ftserv.h (FT_SERVICE_OPENTYPE_VALIDATE_H): New macro. * include/freetype/internal/fttrace.h (otvmodule, otvcommon, otvbase, otvgdef, otvgpos, otvgsub, otvjstf): New trace components. * include/freetype/ftchapters.h: Updated. * src/base/Jamfile (Library), src/base/descrip.mms (OBJS), src/base/rules.mk (BASE_EXT_SRC): Updated. * docs/CHANGES: Updated.
