XF86 keys support.

found and fix by Luis Henriques <henrix@camandro.org>

Spawn a window, maximize it in any way, move the cursor to a window border
that is not on the screen's edge and unmaximize again:  While the window
goes back the cursor stays at the screen's edge, i.e.  focus is lost to the
underlaying window.

Moving, resizing, tiling or snapping windows in any way always moves the
cursor along iff needed, e.g. using MS-[hjkl] to move a small window from
the center to the edge keeps the cursor within window borders -- no matter
what you do with the keyboard, focus stays on that window.

Make CM-f, CM-m, CM-equal and CMS-equal (default bindings) for toggling
full-screen mode, maximization, vertical maximization and horizontal
maximization of the current window drag the cursor along if needed as well.

If a client calls XSetTextProperty for a window to clear all its
properties, then allocated memory within libX11 is not freed.

quoted arguments are stored for other window managers.

The quotation handling happens within the while loop without checking if
the "end" limit has been already reached. If this happens, the final
NULL assignment leads to an out of boundary write on stack.

dosage/removal of wrappers, simplification of name queue, client cycle joins

Behaviour (or lack there of) noticed by Raf Czlonka.

From Artturi Alm (though changed from 'm' to '5')

reported by Stefan Hagen.

there's a window of time where an expose or enternotify event will get
generated for a lower client; use a hammer and drain events after keyboard
move/resize, until such a time that cwm doesn't warp the pointer.  Behavior
noticed by kn.

potential for a use-after-free (true!) where kn@ ran into the regression using
an app that actually exercised the XGrabPointer() failure path.

Link what is described as "applications" here to how they are actually
defined in cwmrc(5).

While here, call the configuration file what it is instead of reusing
the default path (already mentioned in the FILES section).

util.c:u_exec() has been doing so since import.

This fixes the problem where cwm's window menu wouldn't show Firefox's current
window title if it contains non-ASCII characters.

buttonpress handler; bail if we don't manage the screen. Allows us to find the
current client based on the screen/event root.

client thus always falling back to client_current(); while the current client
is problaby right in most cases, use event's subwindow (not window) to find the
client. Bail early if this event came to us from a screen we don't manage.
This is result of us grabing all keybindings off the root window instead of
selectively.

iterating over all (fallback if no screen provided for now). Initially convert
trivial uses of client_current().
