allocation functions with the XPM lib. (struct xpm_cached_color) [ALLOC_XPM_COLORS]: New structure. (XPM_COLOR_CACHE_BUCKETS) [ALLOC_XPM_COLORS]: New macro. (xpm_color_cache) [ALLOC_XPM_COLORS]: New variable. (xpm_init_color_cache, xpm_free_color_cache, xpm_lookup_color) (xpm_alloc_color, xpm_free_colors) [ALLOC_XPM_COLORS]: New functions. (xpm_load) [ALLOC_XPM_COLORS]: Use Emacs' own color allocation functions, if possible, because these handle color allocation failure more gracefully. (Fimage_mask_p): New function.
