(bright_bg): New function, enables bright background colors.

(dos_set_window_size): Move code to `bright_bg'.
(IT_set_terminal_modes): Enable bright background colors.
(IT_set_frame_parameters): Don't mask bright color bit in
background colors.  Record colors on `termscript' file.
(internal_terminal_init): Enable bright background colors.  Fix
default colors setting from $EMACSCOLORS.
