Stop calling fs_unlock() from lv_de/activate(). Start using internal lvm fs cookie for dm_tree. Stop directly calling dm_udev_wait() and dm_tree_set/get_cookie() from activate code - it's now called through fs_unlock() function. Add lvm_do_fs_unlock() Call fs_unlock() when unlocking vg where implicit unlock solves the problem also for cluster - thus no extra command for clustering environment is required - only lvm_do_fs_unlock() function is added to call lvm's fs_unlock() while holding lvm_lock mutex in clvmd. Add fs_unlock() also to set_lv() so the command waits until devices are ready for regular open (i.e. wiping its begining). Move fs_unlock() prototype to activation.h to keep fs.h private in lib/activate dir and not expose other functions from this header.
