The TUI can't really work properly with new-ui, at least not as currently written. This patch changes new-ui to reject an attempt. Attempting to make a DAP ui this way is also now rejected. Regression tested on x86-64 Fedora 38. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29273 Approved-By: Andrew Burgess <aburgess@redhat.com>
