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.
