Modified Files:
        src/lib/libc/stdlib: jemalloc.c

Log Message:
Minor changes to jemalloc100 (the old one that only vax etc currently uses).

- Don't use TLS nor pretend to hash out arenas to reduce lock contention,
  because NetBSD uses thr_curcpu() to choose arena (i.e. per-CPU arenas).

- In a single threaded process, don't prepare "ncpus" worth of arenas,
  allocate only one.

- Use getpagesize() since it caches the return.

- Sprinkle branch hints.

- Make MALLOC_TRACE and MALLOC_DEBUG work again.
