xwm: set the right cursor when hovering on the decoration borders

use the alternative cursor names used also in window.c, since the
names it used previously are not guaranteed to exist in all themes.
Rename current, origin, scale, origin_scale

This patch renames that fields to have consistent names.
Notify clients on mode_switch()

This patch implements the notification of clients during mode_switch.
As discussed on IRC, clients are notified of mode_switch only when the
"native" mode is changed and activated. That means that if the native
mode is changed and the compositor had activated a temporary mode for
a fullscreen surface, the clients will be notified only when the native
mode is restored.
The scaling factor is treated the same way as modes.
input: Emit events on all resources for a client

The Wayland protocol permits a client to request the pointer, keyboard
and touch multiple times from the seat global. This is very useful in a
component like Clutter-GTK where we are combining two libraries that use
Wayland together.

This change migrates the weston input handling code to emit the
events for all the resources for the client by using the newly added
wl_resource_for_each macro to iterate over the resources that are
associated with the focused surface's client.

We maintain a list of focused resources on the pointer and keyboard
which is updated when the focus changes. However since we can have
resources created after the focus has already been set we must add the
resources to the right list and also update any state.

Additionally when setting the pointer focus it will now send the
keyboard modifiers regardless of whether the focused client has a
pointer resource. This is important because otherwise if the client
gets the pointer later than you getting the keyboard then the
modifiers might not be up-to-date.

Add a test client to test multiple pointer/keyboard resources

This adds a hacked version of simple-shm which can create multiple
pointer and keyboard resources. The resources are created with the
command line options -p and -k. Both take an integer argument which
specifies the time in seconds after the program is started when the
resource should be created. It can also take a second time with a
colon separator to specify when the resource should be released.

For example:

 weston-multi-resource -p5 -p7 -k9 -p12:14

That would create a pointer after 5 seconds, a second pointer 2
seconds later, a keyboard 2 seconds after that, a third pointer after
a further 3 seconds and finally after 2 more seconds it would release
that final pointer resource.

This can be used along with WAYLAND_DEBUG to check that it gets the
right events for example if the pointer is created while the client's
surface already has focus and so on.
xwm: remove the destroy listener from the old surface signal
compositor: Unlink unmapped surface instead of rebuilding surface list

When unmap and destroy a surface we need to make sure we don't pick it
before we rebuild the new surface list.  Currently we ensure this
by rebuilding the surface list when destroying a surface, but just
removing the surface should be enough.
terminal: Port to new weston_config parse
window.c: Port to use weston_config instead of old parser
tablet-shell: Use new weston_config instead of old config parse
shared: Remove no longer used parse_config_file()
config-parser: Make weston_config_parse() tkae a file name

Take a basename of the config file to parse instead of an fd.
compositor: Log the full path of the config file we're using
compositor: when unmapping a surface remove it from the compositor's list

compositor.surface_list is recreated every redraw with the mapped
surfaces, but if a surface gets unmapped and then in the same frame
weston_compositor_pick_surface() is called we must make sure it
does not pick the unmapped surface, since it traverses the
surface_list to find one.
If after the unmap the surface gets also deleted it's even more
important, as it must not pick a destroyed surface.
evdev: Flush motion events when the slot changes, not just after sync

If two fingers are released almost simultaneously then evdev can send
the touch up events in one bunch without sending a sync event
in-between. However, the evdev_device struct only keeps track of one
pending touch up event so in this case the second touch up event would
override the first and it would be lost. This patch changes it to also
flush the events whenever the slot changes so that it will flush the
previous touch up event before trying to queue the next one.

input: check that the new focus surface has a valid resource

Here too we must make sure the surface has a valid resource, as
there are some (xwayland, surfaces created by the shell) that
don't have it.
