Use a single parser of color strings in the #RGB, rgb:R/G/B and rgbi:R/G/B formats, replacing four existing ones. Previously, error-checking was spotty, handling of the rgbi: format not always present, and normalization of the result was sometimes incorrect. * src/dispextern.h: New prototype. * src/xfaces.c (parse_hex_color_comp, parse_float_color_comp) (parse_color_spec, Finternal-color_values_from_color_spec): New functions. * test/src/xfaces-tests.el (xfaces-internal-color-values-from-color-spec): New test. * lisp/term/tty-colors.el (tty-color-standard-values): Use internal-color-values-from-color-spec, replacing old parser. * src/nsterm.m (ns_get_color): * src/w32fns.c (x_to_w32_color): * src/xterm.c (x_parse_color): Use parse_color_spec, replacing old parsers. (HEX_COLOR_NAME_LENGTH): Remove #define.
