Dominique Martinet 48e8da851d wlr_seat destroy: fix use-after-free when destroying clients
wl_resource_for_each_safe isn't safe to use here because it accesses
the list's head memory one last time at the end of the loop. Work
around this by breaking out early.

Dominique Martinet 9ddc2f39d0 wlr_seat destroy: fix use-after-free after primary selection source cancel
the primary_selection_source_destroy list points to memory freed by
that cancel callback, so remove from list before freeing

Dominique Martinet 51b9883ea0 seat: allow clients to bind to seat multiple times
This lets clients bind to a seat multiple times by re-using the existing
wlr_seat_client whenever a duplicate request happens.
Previously, an independant wlr_seat_client would be created and only
events from one would be processed.

Fixes #1023.
