* termhooks.h (FRAME_MUST_WRITE_SPACES, FRAME_LINE_INS_DEL_OK)

(FRAME_CHAR_INS_DEL_OK, FRAME_SCROLL_REGION_OK)
(FRAME_SCROLL_REGION_COST, FRAME_MEMORY_BELOW_FRAME):
Adjust to match the change described below.
(struct terminal): Move must_write_spaces, line_ins_del_ok,
char_ins_del_ok, scroll_region_ok, scroll_region_cost and
memory_below_frame members to...
* termchar.h (struct tty_display_info): ...here because they're
relevant only on TTYs.  Prefer unsigned bitfield where appropriate.
* term.c (init_tty):
* nsterm.m (ns_create_terminal):
* w32term.c (w32_create_terminal):
* xterm.c (x_create_terminal): Adjust users.
* dispnew.c (line_hash_code, line_draw_cost): Pass frame arg
to filter out non-TTY frames.  Adjust comment.
(scrolling): Adjust user.  Prefer eassert for debugging check.
