subrepo: avoids empty commit when .hgsubstate is dirty (issue2403)

This patch avoids empty commit when .hgsubstate is dirty. Empty commit
was caused by .hgsubstate being updated back to the state of the
working copy parent when committing, if a user had changed it manually
and not made any changes in subrepositories.

The subrepository state from the working copies parent is compared
with the state calculated as a result of trying to commit the
subrepositories. If the two states are the same, then return None
otherwise the commit is just done.

The line: "committing subrepository x" will be written if there is
nothing committed, but .hgsubstate is dirty for x subrepository.

Rebasing D onto E detaching from C:

  $ hg clone -q -u . a a1
  $ cd a1

  $ hg tglog
  @  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg rebase --detach -s 3 -d 4
  saved backup bundle to $TESTTMP/a1/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  4: 'D'
  |
  o  3: 'E'
  |
  | o  2: 'C'
  | |
  | o  1: 'B'

  o  0: 'A'
  
  $ hg manifest

  $ cd ..


Rebasing C onto E detaching from B:

  $ hg clone -q -u . a a2
  $ cd a2

  $ hg tglog

Rebasing B onto E using detach (same as not using it):

  $ hg clone -q -u . a a3
  $ cd a3

  $ hg tglog
  @  4: 'E'
  |
  | o  3: 'D'

  | o  2: 'C'

  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg rebase --detach -s 1 -d 4
  saved backup bundle to $TESTTMP/a3/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  4: 'D'
  |
  o  3: 'C'

  o  0: 'A'
  
  $ hg manifest

  $ cd ..


Rebasing C onto E detaching from B and collapsing:

  $ hg clone -q -u . a a4
  $ cd a4

  $ hg tglog
  @  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg rebase --detach --collapse -s 2 -d 4
  saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  3: 'Collapsed revision
  |  * C
  |  * D'
  o  2: 'E'
  |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg manifest
  A
  C
  D
  E

  $ cd ..

Rebasing across null as ancestor
  $ hg clone -q -U a a5

  $ cd a5

  $ echo x > x

  $ hg add x

  $ hg ci -m "extra branch"
  created new head

  $ hg tglog
  @  5: 'extra branch'
  
  o  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg rebase --detach -s 1 -d tip
  saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  5: 'D'
