It has been observed (in the HTerm terminal emulator) that the
event stored in the 'xterm-mouse-last-down' terminal parameter gets
overwritten during a mouse drag operation, causing Emacs to attempt to
synthesize the non-existing <drag-mouse-0> event. Copy the event into
the terminal parameter to protect against such modifications.
* lisp/xt-mouse.el (xterm-mouse-translate-1): Guard against modification
of input event list.

(xterm-mouse-tracking-disable-sequence): Replace constants with
functions, mark constants as obsolete.

Always store button numbers in the same way in xterm-mouse-last;
Don't burp is xterm-mouse-last is not set as expected.
Never return negative indices.
Fixes: debbugs:17378
