fileset: add a 'status(...)' predicate to control evaluation context

Same as 'revs', this predicate does not select files but switches the evaluation
context. This allow to match file according arbitrary status call. We can now
express the same query as 'hg status'.

The API (two 'revsingle' class) have been picked instead of a single 'revs'
revset for multiple reasons:

 * it is less confusing to express
 * it allow to express more query (eg: backward status, cross branch status)

  $ fileset() {
  >   hg debugfileset "$@"
  > }

  $ hg init repo
  $ cd repo
  $ echo a > a1
  $ echo a > a2
  $ echo b > b1
  $ echo b > b2
  $ hg ci -Am addfiles
  adding a1
  adding a2

  a2
  $ fileset -v '"re:a\d"'

Test merge states

Test subrepo predicate

  $ hg init sub

  sub
  sub2
  $ fileset 'subrepo("sub")'

  $ fileset 'subrepo("glob:*")'

Test that .hgsubstate is updated as appropriate during a conversion.  The
saverev property is enough to alter the hashes of the subrepo.
