  Position Independent Code (PIC) support in autofit module. * include/freetype/internal/autohint.h add macros to init instances of FT_AutoHinter_ServiceRec. * src/autofit/afmodule.h declare autofit_module_class using macros from ftmodapi.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/autofit/afmodule.c when FT_CONFIG_OPTION_PIC is defined af_autofitter_service and autofit_module_class structs will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from afpic.h in order to access them. * src/autofit/aftypes.h add macros to init and declare instances of AF_ScriptClassRec. * src/autofit/afcjk.h declare af_cjk_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afcjk.c when FT_CONFIG_OPTION_PIC is defined af_cjk_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/afdummy.h declare af_dummy_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afdummy.c when FT_CONFIG_OPTION_PIC is defined af_dummy_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/afindic.h declare af_indic_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/afindic.c when FT_CONFIG_OPTION_PIC is defined af_indic_script_class struct will have function to init it instead of being allocated in the global scope. * src/autofit/aflatin.h declare af_latin_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/aflatin.c when FT_CONFIG_OPTION_PIC is defined af_latin_script_class struct will have function to init it instead of being allocated in the global scope. Change af_latin_blue_chars to be PIC-compatible by being a two dimentional array rather than array of pointers. * src/autofit/aflatin2.h declare af_latin2_script_class using macros from aftypes.h, when FT_CONFIG_OPTION_PIC is defined init function will be declared. * src/autofit/aflatin2.c when FT_CONFIG_OPTION_PIC is defined af_latin2_script_class struct will have function to init it instead of being allocated in the global scope. Change af_latin2_blue_chars to be PIC-compatible by being a two dimentional array rather than array of pointers. * src/autofit/afglobal.c when FT_CONFIG_OPTION_PIC is defined af_script_classes array initialization was moved to afpic.c and is later refered using macros defeined in afpic.h. New Files: * src/autofit/afpic.h declare struct to hold PIC globals for autofit module and macros to access them. * src/autofit/afpic.c implement functions to allocate, destroy and initialize PIC globals for autofit module. * src/autofit/autofit.c add new file to build: afpic.c. * src/autofit/jamfile add new files to FT2_MULTI build: afpic.c.
