Import the slab allocator

As it is intended to completely replace the zone allocator, remove it on
the way. So long to the venerable code !

* Makefrag.am (libkernel_a_SOURCES): Add kern/slab.{c,h}, remove kern/kalloc.c
and kern/zalloc.{c,h}.
* configfrag.ac (SLAB_VERIFY, SLAB_USE_CPU_POOLS): Add defines.
* i386/Makefrag.am (libkernel_a_SOURCES): Remove i386/i386/zalloc.h.
* i386/configfrag.ac (CPU_L1_SHIFT): Remove define.
* include/mach_debug/slab_info.h: New file.
* kern/slab.c: Likewise.
* kern/slab.h: Likewise.
* i386/i386/zalloc.h: Remove file.
* include/mach_debug/zone_info.h: Likewise.
* kern/kalloc.c: Likewise.
* kern/zalloc.c: Likewise.
* kern/zalloc.h: Likewise.
