The 'mode_sigh' function allows the client to receive notifications about server-side display-mode changes. To respond to such a signal, the client can use the new 'release' function, which acknowledges the mode change at the server and frees the original framebuffer dataspace. Via a subsequent call of 'dataspace', a framebuffer dataspace corresponding to the new mode can be obtained. Related to issue #11.
