  Position Independent Code (PIC) support in smooth renderer.
  
  * src/smooth/ftsmooth.h declare ft_smooth_renderer_class,
  ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class
  using macros from ftrender.h,
  when FT_CONFIG_OPTION_PIC is defined create and destroy
  functions will be declared.
  * src/smooth/ftsmooth.c when FT_CONFIG_OPTION_PIC is defined
  the following structs:
  ft_smooth_renderer_class, ft_smooth_lcd_renderer_class
  and ft_smooth_lcd_v_renderer_class
  will have functions to init or create and destroy them
  instead of being allocated in the global scope.
  And macros will be used from ftspic.h in order to access
  ft_grays_raster from the pic_container (allocated in ftgrays.c).
  
  * src/smooth/ftgrays.h include FT_CONFIG_CONFIG_H
  * src/smooth/ftgrays.c when FT_CONFIG_OPTION_PIC is NOT defined
  func_interface was moved from gray_convert_glyph_inner function
  to the global scope.
  When FT_CONFIG_OPTION_PIC is defined
  func_interface and ft_grays_raster structs
  will have functions to init them
  instead of being allocated in the global scope.
  And func_interface will be allocated on the stack of
  gray_convert_glyph_inner.
  
  New Files:
  * src/smooth/ftspic.h declare struct to hold PIC globals for smooth
  renderer and macros to access them.
  * src/smooth/ftspic.c implement functions to allocate, destroy and
  initialize PIC globals for smooth renderer.
  
  * src/smooth/smooth.c add new file to build: ftspic.c.
  * src/smooth/jamfile add new files to FT2_MULTI build: ftspic.c.
