Position Independent Code (PIC) support in psnames module. * include/freetype/internal/services/svpscmap.h add macros to init instances of FT_Service_PsCMapsRec. * src/psnames/psmodule.h declare psnames_module_class using macros from ftmodapi.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/psnames/psmodule.c when FT_CONFIG_OPTION_PIC is defined pscmaps_interface and pscmaps_services structs and psnames_module_class array will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from pspic.h in order to access them. New Files: * src/psnames/pspic.h declare struct to hold PIC globals for psnames module and macros to access them. * src/psnames/pspic.c implement functions to allocate, destroy and initialize PIC globals for psnames module. * src/psnames/psnames.c add new file to build: pspic.c. * src/psnames/jamfile add new files to FT2_MULTI build: pspic.c.
