Pointer passive grabs may be changed by the grabbing client. This allows
for a selecting client to change an implicit grab to an active grab,
which is the mechanism used for pop-up windows like application menus.
We need to do the same thing with touches. If the grabbing client is the
owner of a touch sequence, change the listener record to reflect the new
grab. If the grabbing client is not the owner, nothing changes for the
touch.
