terminal-unix: support mouse escape codes
These 6-byte codes have the format of \e [ M <button> <xpos> <ypos>.
Support the first 3 mouse bottons + scroll up/down for now as
button numbers > 5 are pretty non-portable across terminals.
Pixel-based mouse position values are calculated and sent to the
input system.
