test-revlog-raw: fix "genbits" implementation

The "genbits" implementation is actually incorrect. This patch fixes it. A
good "genbits" implementation should pass the below assertion:

    n = 3 # or other number
    l = list(genbits(n))
    assert 2**(n*2) == len(set((l[i]<<n)+l[i+1] for i in range(len(l)-1)))

An assertion is added to make sure "genbits" won't work unexpectedly.

  o  0:1f0dee641bb7 (draft) [ ] add a
  

check that heads does not report them

  $ hg heads

  $ hg heads --hidden

  $ hg init ../sink

Check that public changeset are not accounted as obsolete:

  $ hg --hidden phase --public 2
  $ hg log -G

And that bumped changeset are detected
--------------------------------------

If we didn't filtered obsolete changesets out, 3 and 4 would show up too. Also
note that the bumped changeset (5:5601fb93a350) is not a direct successor of
the public changeset

  $ hg log --hidden -r 'bumped()'
  5:5601fb93a350 (draft bumped) [tip ] add new_3_c

We need to create a clone of 5 and add a special marker with a flag
