Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.GSoC-2020-greg
