* thunar-vfs/thunar-vfs-unlink-job.c: Allocate dirent buffer for
	  the job instead of the stack on every thunar_vfs_unlink_item_collect
	  call to reduce the stack overhead for the threads.
	* thunar-vfs/thunar-vfs-interactive-job.c: Check the cancellation
	  state prior to invoking the "ask" signal.
	* thunar-vfs/thunar-vfs-interactive-job.{c,h}: Reduce the number
	  of "percent" signal invokations to one per second to reduce the
	  overall load on the main thread.
	* thunar-vfs/thunar-vfs-job.c(thunar_vfs_job_emit_valist): Lower
	  the priority of inter-thread signals.
	* thunar/thunar-progress-dialog.c(thunar_progress_dialog_init): Use
	  an ellipsizing label for the progress info message to avoid
	  automatic resizing of the progress dialog.
	* thunar/thunar-application.{c,h}: Add "copy" and "move" actions. Drop
	  "unlink" action, will be replaced with "trash" and "empty-trash-bin"
	  later.
	* thunar-vfs/thunar-vfs-transfer-job.{c,h}: Import the
	  ThunarVfsTransferJob class, which can only handle 'file:'-URI
	  transfers right now.
