Move command lines types/declarations to cli-script.h

I think it would make more sense if the types and function declarations
related to command lines were in cli-script.h rather than defs.h, since
the related function definitions are in cli-script.c.

I had to add a few includes here and there.  I also had to rename the
"lines" parameter of command_lines_deleter::operator(), because ncurses
has a "#define lines ..." that was interfering when cli-script.h is
included by some TUI source files that also include ncurses header files.

gdb/ChangeLog:

	* cli/cli-script.h (enum misc_command_type): Move from defs.h.
	(enum command_control_type): Likewise.
	(struct command_line): Likewise.
	(free_command_lines): Likewise.
	(struct command_lines_deleter): Likewise.
	(command_line_up): Likewise.
	(read_command_lines): Likewise.
	(read_command_lines_1): Likewise.
	* defs.h (enum misc_command_type): Move to cli/cli-script.h.
	(enum command_control_type): Likewise.
	(struct command_line): Likewise.
	(free_command_lines): Likewise.
	(struct command_lines_deleter): Likewise.
	(command_line_up): Likewise.
	(read_command_lines): Likewise.
	(read_command_lines_1): Likewise.
	* breakpoint.h: Include cli/cli-script.h.
	* extension-priv.h: Likewise.
	* gdbcmd.h: Likewise.
