Instead of having a default set of terminals in terminal-overrides that get XT

added and using that as a marker for xterm(1)-like, assume that if the
terminfo(5) entry already has XT or the clear capability starts with CSI then
the terminal is VT100-like and it should be safe to send DA requests. The DA
responses trigger additional features being added.

This is all to detect extensions if terminfo(5) is wrong or inadequate. If it
fails, tmux will just fall back to using the capabilities in the terminfo(5)
entry alone.
