Otherwise we may try to remove the now invalid ID again, resulting
in a warning.

We are not using return value from meta_error_trap_pop_with_return
if keyboard grab has failed, replace it with meta_error_trap_pop.

g_new bad, g_new0 good.

Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.

Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c

Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)

Root cause tracked down due to much effort by Jon Nettleton.

Treat the empty string the same as "disabled" for GConf keybinding
keys. gnome-keybinding-properties was changed to write disabled
keys as the empty string a year or so ago.

Commit b9cfaa88 removed
meta_display_screen_for_xwindow function. It was supposed to be
replaced with display->screen...

Clear region before calling meta_compositor_sync_window_geometry
function, otherwise compositor will use cached region.

Doing this on the actual resize requests makes more sense
than handling it as a window-manager imposed constraints,
so move the code accordingly.
