  Position Independent Code (PIC) support and infrastructure in base.
  
  * include/freetype/config/ftoption.h add FT_CONFIG_OPTION_PIC
  * include/freetype/internal/ftobjs.h Add pic_container member to
  FT_LibraryRec.
  Add macros to declare and init instances of FT_CMap_ClassRec.
  Add macros to init instances of FT_Outline_Funcs and FT_Raster_Funcs.
  Add macros to declare, allocate and initialize modules
  (FT_Module_Class).
  Add macros to declare, allocate and initialize renderers
  (FT_Renderer_Class).
  Add macro to init instances of FT_Glyph_Class.
  Add macros to declare, allocate and initialize drivers
  (FT_Driver_ClassRec).
  * include/freetype/internal/ftpic.h new file to declare the
  FT_PIC_Container struct and the functions to allocate and detroy it.
  * include/freetype/internal/ftserv.h add macros to allocate and
  destory arrays of FT_ServiceDescRec.
  * include/freetype/internal/internal.h define macro to include
  ftpic.h.
  
  New Files:
  * src/base/ftpic.c implement functions to allocate and destory the
  global pic_container.
  * src/base/basepic.h declare struct to hold PIC globals for base and
  macros to access them.
  * src/base/basepic.c implement functions to allocate, destroy and
  initialize PIC globals for base.
  
  * src/base/ftinit.c when FT_CONFIG_OPTION_PIC is defined implement
  functions that allocate and destroy ft_default_modules according to
  FT_CONFIG_MODULES_H in the pic_container instead of the global scope
  and use macro from basepic.h to access it.
  * src/base/ftobjs.c add calls to the functions that allocate and
  destroy the global pic_container when the library is created and
  destroyed.
  
  * src/base/jamfile add new files to FT2_MULTI build:
  ftpic.c and basepic.c.
  * src/base/ftbase.c add new files to build:
  ftpic.c and basepic.c.
  
  * src/base/ftglyph.c when FT_CONFIG_OPTION_PIC is defined
  ft_bitmap_glyph_class and ft_outline_glyph_class will be allocated
  in the pic_container instead of the global scope and use macros from
  basepic.h to access them.
  * src/base/ftbbox.c allocate bbox_interface stract on the stack
  instead of the global scope when FT_CONFIG_OPTION_PIC is defined.
  * src/base/ftstroke.c access ft_outline_glyph_class allocated in
  ftglyph.c via macros from basepic.h
