    stapdyn: Enable map and stat types
    There are a lot of kernel-isms in the map code especially, and rather
    than try to rewrite all that, I've simply copied the necessary bits from
    the kernel.  The new pieces are mostly list and hash related.
    * runtime/dyninst/alloc.c (_stp_alloc_percpu): Needs to be zeroed.
    * runtime/dyninst/runtime.h: Add BITS_PER_LONG and stap_hash_seed.
      Also extract various bits copied from the kernel into new files.
    * runtime/dyninst/linux_types.h: Reused Linux type definitions.
    * runtime/dyninst/linux_defs.h: Other various reused Linux code.
    * runtime/dyninst/linux_hash.h: Direct copy of hashing from Linux.
    * runtime/dyninst/ilog2.h: Linux's ilog2(), but just for constants.
    * runtime/dyninst/probe_lock.h: Typedef rwlock_t on pthreads.
    * runtime/map.c: Don't need sym.c, and emulate ALIGN().
    * runtime/map.h: Locate ilog2, and fix NEED_MAP_LOCKS check.
