  Add Adobe engine configuration. Use the previously changed PS_Driver in type1 module to store hinting engine configuration. * include/freetype/ftt1drv.h: New file. Duplicate and rename config options from CFF. * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. * src/type1/t1driver.c (t1_driver_class): Update declaration. * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. (T1_Driver_Init): Update code.

     *   Thanks to Adobe, which contributed a new hinting (and parsing)
     *   engine, an application can select between `freetype' and `adobe' if
     *   compiled with T1_CONFIG_OPTION_OLD_ENGINE.  If this configuration
     *   macro isn't defined, `hinting-engine' does nothing.
     *
     *   The default engine is `freetype' if T1_CONFIG_OPTION_OLD_ENGINE is
     *   defined, and `adobe' otherwise.
     *
     *   The following example code demonstrates how to select Adobe's hinting
     *   engine (omitting the error handling).
     *
     *   {
     *     FT_Library  library;
     *     FT_UInt     hinting_engine = FT_T1_HINTING_ADOBE;

     *   }
     *
     * @note:
     *   This property can be used with @FT_Property_Get also.
     *
     *   This property can be set via the `FREETYPE_PROPERTIES' environment
     *   variable (using values `adobe' or `freetype').
