* cygtls.h (_cygtls): Perform minor reformatting.

Browse Source 
* winsup.h (close_all_files): Reflect argument change.
* dtable.cc (close_all_files): Ditto.
* dtable.h: Ditto.
* fhandler.h: Ditto.
* spawn.cc (spawn_guts): Move close_all_files back to its original location in
first P_OVERLAY test but use argument denoting that handles are only supposed
to be closed, not released (more work to be done here).
* syscalls.cc (close_all_files): Take an argument denoting whether to release
closed files or not.
* path.cc (symlink): Change argument names to reflect linux man page.
(symlink_worker): Ditto.  Also appropriately set ENOENT for empty strings.
