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.

* 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/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.
