Alan Cox 29b45e9e99 vm_map_insert sometimes extends an existing vm_map entry, rather than
creating a new entry.  vm_map_stack and vm_map_growstack can panic when
a new entry isn't created.  Fixed vm_map_stack and vm_map_growstack.

Also, when extending the stack, always set the protection to VM_PROT_ALL.
