data-device: add a function to send the selection to a client

This commit adds a new exported function, weston_seat_send_selection(),
which sends the current selection to a specified client. This is
useful e.g. to implement a clipboard manager as a special client.

/** \brief Send the selection to the specified client
*
* This function creates a new wl_data_offer if there is a wl_data_source
* currently set as the selection and sends it to the specified client,
* followed by the wl_data_device.selection() event.
* If there is no current selection the wl_data_device.selection() event
* will carry a NULL wl_data_offer.
*
* If the client does not have a wl_data_device for the specified seat
* nothing will be done.
*
* \param seat The seat owning the wl_data_device used to send the events.
* \param client The client to which to send the selection.
