subrepo: handle svn tracked/unknown directory collisions

This happens more often than expected. Say you have an svn subrepository with
python code. Python would have generated unknown .pyc files. Now, you rebase
this setup on a revision where a directory containing python code does not
exist. Subversion is first asked to remove this directory when updating, but
will not because it contains untracked items. Then it will have to bring back
the directory after the merge but will fail because it now collides with an
untracked directory.

Using --force is not very elegant and only works with svn >= 1.5 but the only
alternative I can think of is to write our own purge command for subversion.

  $ hg init a
  $ cd a

  $ echo A > A
  $ hg ci -Am A
  adding A

  $ echo B > B
  $ hg ci -Am B
  adding B

  $ echo C > C
  $ hg ci -Am C
  adding C

  $ echo D > D
  $ hg ci -Am D
  adding D

  $ hg up -q -C 0

  $ echo E > E
  $ hg ci -Am E
  adding E
  created new head

  $ cd ..


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
  A
  D
  E

  $ cd ..


Rebasing C onto E detaching from B:

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

  $ hg tglog
  @  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ hg rebase --detach -s 2 -d 4
  saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)

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

  $ cd ..


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  2: 'B'
  |
  o  1: 'E'
  |
  o  0: 'A'
  
  $ hg manifest
  A
  B
  C
  D
  E

  $ 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'
  |
  o  4: 'C'
  |
  o  3: 'B'
  |
  o  2: 'extra branch'
  
  o  1: 'E'
  |
  o  0: 'A'
