[PATCH 0/3] [gdb/tui] Improve handling of inferior output

[Tom de Vries <tdevries@suse.de>]

When inferior output in TUI causes scrolling, the TUI screen is garbled.  This
is a known issue, PR tui/14332.

This can be fixed manually by doing ^L.

I noticed though that doing ^L removes the inferior output.

The first patch fixes this.

The third patch automates doing ^L when the gdb_tty_state changes to
target_terminal_state::is_ours, such what we no longer have to do ^L.

The second patch is an infrastructure patch used by the third patch.

Tested on x86_64-linux.

Tom de Vries (3):
  [gdb/tui] Keep inferior output in cmd window with ^L
  [gdb] Add observable terminal_owner_changed
  [gdb/tui] Refresh on target_terminal_state::is_ours
