  [autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'.
