Merge branch 'fix/ppc64' into next

* fix/ppc64:
  minor, clarify usage of ase_ffsl in skiplist.c
  minor, provide (missing) ffsl for ppc64 and flsl for ppc and ppc64
  minor, provide __next_2power() from the bithacks web site
  cosmetics, include ent/ent.h (or one of its sub-includes) directly, take 2, ...
  cosmetics, include ent/ent.h (or one of its sub-includes) directly ...
  cosmetics, do not include all of ent.h in lisp.h ...

This changeset fixes issues with the ppc64 build whilst cleaning up
the lisp header (lisp.h) at the same time.
