[PATCH 0/1] MR4695: Draft: winewayland.drv: Support mouse buttons 4 and 5.

[Alexandros Frantzis (＠afrantzis)]

Map linux mouse buttons to win32 XBUTTON1 and XBUTTON2. Although
BTN_SIDE and BTN_EXTRA are the typical event codes for these buttons,
some drivers use BTN_BACK and BTN_FORWARD, so map both pairs.
