revset: fix iteration over ordered addset composed of non-ordered operands

Before this change, doing ordered iteration over an 'addset' object composed of
operands without fastasc or fastdesc method could result in duplicated entries.
This was the result of applying '_iterordered' on an unordered set.

We fix it by ensuring we iterate over the set in a sorted order. Using the fast
iterator when it exists on any operand. We kill the '_iterator' method in the
process because it did not make a lot of sense independently.

Thanks goes to Yuya Nishihara for reporting the issue and analysing the cause.

Test encode/decode filters

  $ hg init
  $ cat > .hg/hgrc <<EOF
  > [encode]
  > not.gz = tr [:lower:] [:upper:]
  > *.gz = gzip -d
  > [decode]
  > not.gz = tr [:upper:] [:lower:]
  > *.gz = gzip
  > EOF
  $ echo "this is a test" | gzip > a.gz
  $ echo "this is a test" > not.gz
  $ hg add *
  $ hg ci -m "test"

no changes

  $ hg status
  $ touch *

no changes

  $ hg status

check contents in repo are encoded

  $ hg debugdata a.gz 0
  this is a test
  $ hg debugdata not.gz 0
  THIS IS A TEST

check committed content was decoded

  $ gunzip < a.gz
  this is a test
  $ cat not.gz
  this is a test
  $ rm *
  $ hg co -C
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

check decoding of our new working dir copy

  $ gunzip < a.gz
  this is a test
  $ cat not.gz
  this is a test

check hg cat operation

  $ hg cat a.gz
  this is a test
  $ hg cat --decode a.gz | gunzip
  this is a test
  $ mkdir subdir
  $ cd subdir
  $ hg -R .. cat ../a.gz
  this is a test
  $ hg -R .. cat --decode ../a.gz | gunzip
  this is a test

  $ cd ..
