This avoids hitting the assert that we don't have any paint nodes in
available when the repaint loop starts.
As we only have just a single curtain, in multi-head/outputs case a new
output creation will destroy the previous curtain and we'll end up
hitting the empty paint nodes assert.
Note that this doesn't add any functionality it just makes sure we're actually
capable of running the lua-shell rather than dying.

We've added a curtain to the shells so at startup we have something to
render, but this causes a flicker if someone is trying to have a seamless
transition from boot to weston.
Add a ready flag that allows the shell to indicate repaints are safe, so
we can remove the curtains and have no wasted frames at startup.

Replace two always-true assertions:
weston_assert_true(wc, &other_shview->view->layer_link.layer);
with what seems to have been the intended check:
weston_assert_ptr_not_null(wc, other_shview->view->layer_link.layer);
This fixes a build warning:
.../lua-shell/lua-shell.c: In function 'lua_shell_env_view_move_behind_other_view':

When resizing the outputs, re-create the background and relayout the
views according to the (newer) output dimensions.
This is a common feature amongs our shells, so do this for lua-shell as
well.

lua-shell is a new meta-shell for Weston. It does nothing in and of
itself, but is defined to be user-scriptable and configurable. A
supplied Lua script will be interpreted and executed by Weston, allowing
full control over window management in response to events.
This includes a shell.lua example script which behaves as a tiling WM.
