Add TUI border colors
This adds the ability to change the color of the TUI borders, both ordinary and active. Unlike other styling options, this doesn't allow setting the intensity, because that is already done by the TUI in a different way. gdb/ChangeLog 2019-12-01 Tom Tromey <tom@tromey.com> * NEWS: Document new settings. * tui/tui-wingeneral.c (box_win): Apply appropriate border style. * tui/tui-win.c (_initialize_tui_win): Add border style observers. * tui/tui-io.h (tui_apply_style): Declare. * tui/tui-io.c (tui_apply_style): Rename from apply_style.
