inhibit: improve performance of transaction wrapping

Before this patch, transaction wrapping was the most expensive part of inhibit
computation wise. This patch changes the revset that we use in the transaction
wrapping to make it ~50x faster to compute:


revset #0: obsolete() - hidden()
0) wall 0.000214 comb 0.000000 user 0.000000 sys 0.000000 (best of 11209)

vs

revset #0: (not hidden()) and obsolete()
0) wall 0.010965 comb 0.010000 user 0.010000 sys 0.000000 (best of 237)

  $ hg init repo
  $ cd repo
  $ echo A > a
  $ hg add a
  $ hg commit -m a

Basic usage

  $ hg log -G
  @  0:e93df3427f45 a
  
  $ hg touch .
  $ hg log -G
  @  1:[0-9a-f]{12} a (re)
  


Revive usage

  $ echo A > b
  $ hg add b
  $ hg commit -m ab --amend
  $ hg up --hidden 1
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  working directory parent is obsolete!
  $ hg log -G
  o  3:[0-9a-f]{12} ab (re)
  
  @  1:[0-9a-f]{12} a (re)
  
  $ hg touch .
  2 new divergent changesets
  $ hg log -G
  @  4:[0-9a-f]{12} a (re)
  
  o  3:[0-9a-f]{12} ab (re)
  
  $ hg prune 3
  1 changesets pruned

Duplicate

  $ hg touch --duplicate .
  $ hg log -G
  @  5:[0-9a-f]{12} a (re)
  
  o  4:[0-9a-f]{12} a (re)
  

Multiple touch

  $ echo C > c
  $ hg add c
  $ hg commit -m c
  $ echo D > d
  $ hg add d
  $ hg commit -m d
  $ hg log -G
  @  7:[0-9a-f]{12} d (re)
  |
  o  6:[0-9a-f]{12} c (re)
  |
  o  5:[0-9a-f]{12} a (re)
  
  o  4:[0-9a-f]{12} a (re)
  
  $ hg touch 6:7
  $ hg log -G
  @  9:[0-9a-f]{12} d (re)
  |
  o  8:[0-9a-f]{12} c (re)
  |
  o  5:[0-9a-f]{12} a (re)
  
  o  4:[0-9a-f]{12} a (re)
  

check move data kept after rebase on touch:

  $ touch gna1
  $ hg commit -Am gna1
  adding gna1
  $ hg mv gna1 gna2
  $ hg commit -m move
  $ hg st -C --change=tip
  A gna2
    gna1
  R gna1
  $ hg up .^
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ hg touch
  1 new unstable changesets

  $ hg rebase -s 11 -d 12
  rebasing 11:* "move" (glob)
  $ hg st -C --change=tip
  A gna2
    gna1
  R gna1
