group_show() and group_hide() are not the only ways a group can change
state - if all clients in a group are either hidden or unhidden, then
that group's state should change, as well as the various EWMH ways.
Instead of trying to keep track in a wide variety of places, simply
query the clients in a group before needing to take action based on the
group's state. Solves long standing confusion of when a group is hidden
or not.
symantics between cwm groups and ewmh got in the way. Ensure a client
that wants to be in nogroup stays in nogroup (thus stays in view), even
when (re)reading NET_WM_DESKTOP. Paritially reverts patchset 644
(2014-02-07 13:09 PST) which deals with a NULL cc->group. All to be
revisited when NET_WM_STATE_STICKY hits cwm.
Reported by many; testing and ok phessler.
since nhidden wasn't incremented nor decremeted in all the right places,
thus confusing matters. We don't need to carry a count around, so just
use a local variable in the one place we need one to supply
XRestackWindows().
/etc/X11/app-defaults stays 1st in the libXt search path so, people
and ports can put customized versions there if needed.
If you didn't customize the versions in /etc/X11/app-defaults, they
should be removed to avoid future issues when one file changes.

As the functions check if the member pointers are NULL but not the
pointer to the struct itself.
Reworked version of a diff from ratchov@ who created it to prevent a
xserver crash on zaurus where there is no PCI.

symbols from libgbm, and that breaks www/webkit (and probably all the 23
ports linking against EGL, which now probably need WANTLIB fixes..)
