revlog: give EXTSTORED flag value to narrowhg

Narrowhg has been using "1 << 14" as its revlog flag value for a long
time. We (Google) have many repos with that value in production
already. When the same value was reserved for EXTSTORED, it made those
repos invalid. Upgrading them will be a little painful. We should
clearly have reserved the value for narrowhg a long time ago. Since
the EXTSTORED flag is not yet in any release and Facebook also says
they have not started using it in production, so it should be okay to
change it. This patch gives the current value (1 << 14) back to
narrowhg and gives a new value (1 << 13) to EXTSTORED.

Test order of revisions in compound expression
----------------------------------------------

The general rule is that only the outermost (= leftmost) predicate can
enforce its ordering requirement. The other predicates should take the
ordering defined by it.

 'A & B' should follow the order of 'A':

  $ log '2:0 & 0::2'
  2
  1
  0

 'head()' combines sets in right order:

  $ log '2:0 & head()'
  2
  1
  0

 'x:y' takes ordering parameter into account:

  $ try -p optimized '3:0 & 0:3 & not 2:1'
  * optimized:
  (difference
    (and
      (range
        ('symbol', '3')
        ('symbol', '0')
        define)
      (range
        ('symbol', '0')
        ('symbol', '3')
        follow)
      define)
    (range
      ('symbol', '2')
      ('symbol', '1')
      any)
    define)
  * set:
  <filteredset
    <filteredset
      <spanset- 0:3>,
      <spanset+ 0:3>>,
    <not
      <spanset+ 1:2>>>
  3
  0

 'a + b', which is optimized to '_list(a b)', should take the ordering of
 the left expression:

  $ try --optimize '2:0 & (0 + 1 + 2)'
  (and
    (range
      ('symbol', '2')
      ('symbol', '0'))
    (group
      (or
        (list
          ('symbol', '0')
          ('symbol', '1')
          ('symbol', '2')))))
  * optimized:
  (and
    (range
      ('symbol', '2')
      ('symbol', '0')
      define)
    (func
      ('symbol', '_list')
      ('string', '0\x001\x002')
      follow)
    define)
  * set:
  <filteredset
    <spanset- 0:2>,
    <baseset [0, 1, 2]>>
  2
  1
  0

 'A + B' should take the ordering of the left expression:

  $ try --optimize '2:0 & (0:1 + 2)'
  (and
    (range
      ('symbol', '2')
      ('symbol', '0'))
    (group
      (or
        (list
          (range
            ('symbol', '0')
            ('symbol', '1'))
          ('symbol', '2')))))
  * optimized:
  (and
    (range
      ('symbol', '2')
      ('symbol', '0')
      define)
    (or
      (list
        (range
          ('symbol', '0')
          ('symbol', '1')
          follow)
        ('symbol', '2'))
      follow)
    define)
  * set:
  <filteredset
    <spanset- 0:2>,
    <addset
      <spanset+ 0:1>,
      <baseset [2]>>>

 'A & B' can be rewritten as 'B & A' by weight, but that's fine as long as
 the ordering rule is determined before the rewrite; in this example,
 'B' follows the order of the initial set, which is the same order as 'A'
 since 'A' also follows the order:

  $ try --optimize 'contains("glob:*") & (2 + 0 + 1)'
  (and
    (func
      ('symbol', 'contains')
      ('string', 'glob:*'))
    (group
      (or
        (list
          ('symbol', '2')
          ('symbol', '0')
          ('symbol', '1')))))
  * optimized:
  (and
    (func
      ('symbol', '_list')
      ('string', '2\x000\x001')
      follow)
    (func
      ('symbol', 'contains')
      ('string', 'glob:*')
      define)
    define)
  * set:
  <filteredset
    <baseset+ [0, 1, 2]>,
    <contains 'glob:*'>>
  0
  1
  2

 and in this example, 'A & B' is rewritten as 'B & A', but 'A' overrides
 the order appropriately:

  $ try --optimize 'reverse(contains("glob:*")) & (0 + 2 + 1)'
  (and
    (func
      ('symbol', 'reverse')
      (func
        ('symbol', 'contains')
        ('string', 'glob:*')))
    (group
      (or
        (list
          ('symbol', '0')
