Test that terminal settings are restored after quitting via SIGTERM
Tested on x86_64 Debian Stretch, native, gdbserver and extended-gdbserver. Also tested that the various error paths, like if $PPID is empty or if SIGTERM did not not kill GDB, function correctly. gdb/testsuite/ChangeLog: * gdb.base/batch-preserve-term-settings.exp (send_quit_command): New proc. (test_terminal_settings_preserved_after_sigterm): New test.
