[PATCH 0/4] [gdb/tui] Fix hang in tui_disable in handle_fatal_signal

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

This patch series contains four patches.

The first adds missing logging_file::fd.

The second updates test-case gdb.tui/new-ui.exp to issue a
"maint internal-error" from a new UI while the main UI is in TUI mode.

The third patch tries to handle that scenario better, by actually triggering
an internal error.

The last patch fixes PR34732.

Tested on x86_64-linux.
