Fix -Wall compiler warnings in MSDOS sources.

msdos.c (IT_set_face): Fix format string to match argument types. (IT_write_glyphs, IT_note_mode_line_highlight) (IT_set_frame_parameters): Remove unused variables. (x_set_menu_bar_lines): Declare set_menu_bar_lines. (IT_set_terminal_modes): Disambiguate expression in if clause. (Fmsdos_remember_default_colors): Return Qnil. (IT_set_frame_parameters): Add parens to disambiguate boolean expression for logging the cursor type to termscript. (keyboard_layout_list, keypad_translate_map) (grey_key_translate_map): Add braces in inner initializers. (dos_rawgetc): Add parens in condition for mouse-3 button-press. (dos_rawgetc): Remove unused label. (XMenuActivate): Add braces to remove ambiguous `else'. (dos_ttraw): Always return a value. (spawnve): Declare. (run_msdos_command): Cast 3rd arg of spawnve to "char **". dosfns.h (x_set_title): Declare. w16select.c (Fw16_set_clipboard_data, Fw16_get_clipboard_data): Remove unused variables. dosfns.c (Fint86, Fdos_memget, Fdos_memput): Remove unused variables. (init_dosfns): Declare get_lim_data. (system_process_attributes): Declare Fget_internal_run_time.
