Avoid hourglass mouse pointer when a tooltip for menu item is shown.

 src/w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
 mouse movement events if the menu bar is active.  This avoids
 producing a busy "hour-glass" cursor by Windows if the mouse
 pointer is positioned over a tooltip shown for some menu item.

Fix w32 implementation of itimers: overflow and ITIMER_PROF.

 Avoid overflow in w32 implementation of interval timers.  When
 possible, for ITIMER_PROF count only times the main thread
 actually executes.

 previously clock_t.
