Fix stack allocation on Xen
Stack allocation on Xen can fail because of fragmentation. This change
makes stack allocation use the slab allocator.
* kern/thread.c (thread_stack_cache): New global variable.
(stack_alloc): Use kmem_cache_alloc instead of vm_page_grab_contig.
(stack_collect): Use kmem_cache_free instead of vm_page_free_contig.
(kmem_cache_init): Initialize thread_stack_cache.
