store: return just one filename in walk functions

Various walk functions return `(revlog_type, decoded, encoded)` where
decoded could be None. But no-one cares about `encoded` and expects
`unencoded` to be present, except verify (because this can only happen
with old repo formats).

Simplify all this by either failing outright if a decoding a filename
fails (instead of almost certainly failing with a type error due to
treating None as a bytes), or skipping the filename but providing in
an out argument for hg verify.

#require no-pure

A script to generate nasty diff worst-case scenarios:

  $ cat > s.py <<EOF
  > import random
  > for x in range(100000):
  >     print
  >     if random.randint(0, 100) >= 50:
  >         x += 1
  >     print(hex(x))
  > EOF

  $ hg init a
  $ cd a

Check in a big file:

  $ "$PYTHON" ../s.py > a
  $ hg ci -qAm0

Modify it:

  $ "$PYTHON" ../s.py > a

Time a check-in, should never take more than 10 seconds user time:

  $ hg ci --time -m1 --config worker.enabled=no
  time: real .* secs .user [0-9][.].* sys .* (re)
