	* thunar-vfs/thunar-vfs-io-local-xfer.c,
	  thunar-vfs/thunar-vfs-mime-database.c,
	  thunar-vfs/thunar-vfs-monitor.c, thunar-vfs/thunar-vfs-os-bsd.c,
	  thunar-vfs/thunar-vfs-os-generic.c, thunar-vfs/thunar-vfs-path.c,
	  thunar-vfs/thunar-vfs-path-private.h,
	  thunar-vfs/thunar-vfs-transfer-job.c: Add _thunar_vfs_path_child()
	  as internal implementation of thunar_vfs_path_relative(), that does
	  not perform the expensive sanity checking for release builds.
	* thunar-vfs/thunar-vfs.c(_thunar_vfs_init): Do not maintain more than
	  four unused threads, and stop unused threads after ten seconds of
	  idle time (requires GLib 2.10).
	* thunar-vfs/thunar-vfs-io-local.{c,h}: List folders parallel again,
	  with up to four threads collecting file infos at the same time.
	  Additionally, in order to avoid the costly inode lookups when
	  listing folder contents, we change to the requested folder and
	  use relative file names (requires locking, since the current
	  working directory is per-process rather than per-thread). Last,
	  the executable sanity checking was optimized for the common case
	  of a binary or shellscript, which should further improve the
	  loading performance of large folders with binaries.
