  [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could *ever* be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.
