[PATCH 51/66] Remove layout_def::split

[Tom Tromey]

The "split" field in struct layout_def is never used, so this patch
removes it.

2019-06-23  Tom Tromey  <tom@tromey.com>

	* tui/tui-layout.c (tui_set_layout): Update.
	* tui/tui-data.h (struct tui_layout_def) <split>: Remove.
	* tui/tui-data.c (layout_def): Update.
