merge: store cases when a file is absent post merge in commitinfo

Some merges can result in file being absent form working directory. This can be
one of file was kept deleted or file was removed by merge code.

User might revert the file back before committing. In such cases we will like to
have better handling and create new filenodes.

We store this info in mergestate as commitinfo so that we can use it while
committing to create new filenode if required.

  $ hg init
  $ echo a > a
  $ mkdir b
  $ echo b > b/b
  $ hg commit -A -m "a is file, b is dir"
  adding a
  adding b/b

File replaced with directory:

  $ rm a
  $ mkdir a
  $ echo a > a/a

Should fail - would corrupt dirstate:

  $ hg add a/a
  abort: file 'a' in dirstate clashes with 'a/a'
  [255]

Removing shadow:

  $ hg rm --after a

Should succeed - shadow removed:

  $ hg add a/a

Directory replaced with file:

  $ rm -r b
  $ echo b > b

Should fail - would corrupt dirstate:

  $ hg add b
  abort: directory 'b' already in dirstate
  [255]

Removing shadow:

  $ hg rm --after b/b

Should succeed - shadow removed:

  $ hg add b

Look what we got:

  $ hg st
  A a/a
  A b
  R a
  R b/b

Revert reintroducing shadow - should fail:

  $ rm -r a b
  $ hg revert b/b
  abort: file 'b' in dirstate clashes with 'b/b'
  [255]

Revert all - should succeed:

  $ hg revert --all
  forgetting a/a
  forgetting b
  undeleting a
  undeleting b/b

  $ hg st

Issue3423:

  $ hg forget a
  $ echo zed > a
  $ hg revert a
  $ hg st
  ? a.orig
  $ rm a.orig

addremove:

  $ rm -r a b
  $ mkdir a
  $ echo a > a/a
  $ echo b > b

  $ hg addremove -s 0
  removing a
  adding a/a
  adding b
  removing b/b

  $ hg st
  A a/a
  A b
  R a
  R b/b

commit:

  $ hg ci -A -m "a is dir, b is file"
  $ hg st --all
  C a/a
  C b

Long directory replaced with file:

  $ mkdir d
  $ mkdir d/d
  $ echo d > d/d/d
  $ hg commit -A -m "d is long directory"
  adding d/d/d

  $ rm -r d
  $ echo d > d

Should fail - would corrupt dirstate:

  $ hg add d
  abort: directory 'd' already in dirstate
  [255]

Removing shadow:

  $ hg rm --after d/d/d

Should succeed - shadow removed:

  $ hg add d
  $ hg ci -md

Update should work at least with clean working directory:

  $ rm -r a b d
  $ hg up -r 0
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg st --all
  C a
  C b/b

  $ rm -r a b
  $ hg up -r 1
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg st --all
  C a/a
  C b
