desktop-shell: add option to avoid creating the panel

This option is so we can disable showing any panel at all. The default
is to continue showing the panel and no example is added to weston.ini
because it's an uncommon request.

gears: fix invalid calculation of the first FPS

At the calculation of the first FPS, gears has initialized last
FPS time with gettimeofday().
But the callback_data passed in the callback of wl_surface_frame()
is the current time, in milliseconds, with an undefined base.
Because of this subtracting last FPS time from callback_data makes no sense.
 For example, below is the result of running weston-gears on weston with
drm backend:

$ weston-gears
Warning: FPS count is limited by the wayland compositor or monitor refresh rate
1 frames in 1094460.125 seconds =  0.000 FPS
301 frames in  5.016 seconds = 60.008 FPS
301 frames in  5.016 seconds = 60.008 FPS
301 frames in  5.016 seconds = 60.008 FPS

As you can see, the the first FPS value is something odd.

This patch fixes it by initializing last FPS time with the callback_data passed in
the first callback.

shell: Update focused surface pointer coordinates in popup grab

The commit 'input: Send leave and enter pair when the surface moves
under the cursor' introduced focused surface local pointer coordinates
to keep track of if a surface had been moved or transformed in a way
that the pointer posititon relative to that surface would change.
Update these coordinates also for the popup grab as otherwise every
pointer motion during a popup grab results in leave and then enter
events.

xwm: check whether the picked seat can be NULL

The seat picked in weston_wm_window_handle_moveresize can sometimes
be NULL when it is (somehow) triggered with all buttons released.

This patch checks whether the seat is NULL to avoid NULL dereference.

Libinput is stabilizing soon, so let's flip the default switch now. The

Replace deprecated xkbcommon symbols with current names

These symbols (xkb_map_* and others) were replaced in xkbcommon with more
consistent names. See the header xkbcommon/xkbcommon-compat.h for how
the old names map to the new.

The new names have been available since the first stable xkbcommon
release (0.2.0).
