Augment VM maps with task names
This change improves the clarity of "no more room for ..." VM map
allocation errors.
* kern/task.c (task_init): Call vm_map_set_name for the kernel map.
(task_create): Call vm_map_set_name where appropriate.
* vm/vm_map.c (vm_map_setup): Set map name to NULL.
(vm_map_find_entry_anywhere): Update error message to include map name.
* vm/vm_map.h (struct vm_map): New `name' member.
(vm_map_set_name): New inline function.
