Add new service for inter-module calls. 

NOTE: Does not compile!

This is to allow CFF functions moved to `psaux' to call functions
declared in `src/cff/cffload.h'.

* include/freetype/internal/services/svcfftl.h: New file, setting up
a `CFFLoad' service.

* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC10,
FT_DEFINE_SERVICEDESCREC): New macros.
(FT_SERVICE_CFF_TABLE_LOAD_H): New macro.

* src/cff/cffdrivr.c, src/cff/cffpic.h: Register the new service.

* src/cff/cfftypes.h (CFF_FontRec), src/psaux/cf2font.h
(CF2_FontRec): Add service interface.

* src/cff/cffobjs.c, src/psaux/cf2font.c, src/psaux/cf2ft.c,
src/psaux/cf2intrp.c, src/psaux/cffdecode.c: Use the new service.
