mousemode.c ADB Reset patch

[Tom Harrington]

Below is a patch for mousemode.c that I hacked up.  It adds an "ADB
reset" option to the code.  I don't know if it's useful to anyone
not hacking ADB code (and occasionally causing devices to stop responding),
but feel free to use it if you like it.

What happens is, if you do "mousemode -1", the address is caught.  Rather
than try to use the address, the new reset_adb() function is called.
