commit: get info from mergestate whether a file was merged or not

While commiting a merge, the commit code does not know whether a file was merged
during `hg merge` or not. This leads the commit code to look for filelog
ancestor to choose parents of new filelog created on merge commit.
This leads to wrong results in some cases as demonstrated by previous patch.

From this patch, we start storing information about merged files in mergestate
in stateextras and then use that on commit to detect whether we need to set two
parents or not.

Test 'hg log' with a bookmark


Create the repository

  $ hg init Test-D8973
  $ cd Test-D8973
  $ echo "bar" > foo.txt
  $ hg add foo.txt
  $ hg commit -m "Add foo in 'default'"


Add a bookmark for topic X

  $ hg branch -f sebhtml
  marked working directory as branch sebhtml
  (branches are permanent and global, did you want a bookmark?)

  $ hg bookmark sebhtml/99991-topic-X
  $ hg up sebhtml/99991-topic-X
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo "X" > x.txt
  $ hg add x.txt
  $ hg commit -m "Add x.txt in 'sebhtml/99991-topic-X'"

  $ hg log -B sebhtml/99991-topic-X
  changeset:   1:29f39dea9bf9
  branch:      sebhtml
  bookmark:    sebhtml/99991-topic-X
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     Add x.txt in 'sebhtml/99991-topic-X'
  

Add a bookmark for topic Y

  $ hg update default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (leaving bookmark sebhtml/99991-topic-X)

  $ echo "Y" > y.txt
  $ hg add y.txt
  $ hg branch -f sebhtml
  marked working directory as branch sebhtml
  $ hg bookmark sebhtml/99992-topic-Y
  $ hg up sebhtml/99992-topic-Y
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg commit -m "Add y.txt in 'sebhtml/99992-topic-Y'"
  created new head

  $ hg log -B sebhtml/99992-topic-Y
  changeset:   2:11df7969cf8d
  branch:      sebhtml
  bookmark:    sebhtml/99992-topic-Y
  tag:         tip
  parent:      0:eaea25376a59
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     Add y.txt in 'sebhtml/99992-topic-Y'
  

The log of topic Y does not interfere with the log of topic X

  $ hg log -B sebhtml/99991-topic-X
  changeset:   1:29f39dea9bf9
  branch:      sebhtml
  bookmark:    sebhtml/99991-topic-X
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     Add x.txt in 'sebhtml/99991-topic-X'
  

Merge topics Y and X in the default branch

  $ hg update default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (leaving bookmark sebhtml/99992-topic-Y)

  $ hg bookmark
     sebhtml/99991-topic-X     1:29f39dea9bf9
     sebhtml/99992-topic-Y     2:11df7969cf8d

  $ hg merge sebhtml/99992-topic-Y
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ hg commit -m "Merge branch 'sebhtml/99992-topic-Y' into 'default'"

  $ hg update default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg merge sebhtml/99991-topic-X
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ hg commit -m "Merge branch 'sebhtml/99991-topic-X' into 'default'"


Check the log of topic X, topic Y, and default branch

  $ hg log -B sebhtml/99992-topic-Y

  $ hg log -B sebhtml/99991-topic-X

  $ hg log -b default

Set up multiple bookmarked heads:

  $ hg bookmark merged-head
  $ hg up 1
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (leaving bookmark merged-head)
  $ echo "Z" > z.txt
  $ hg ci -Am 'Add Z'
  adding z.txt
  $ hg bookmark topic-Z

  $ hg log -GT '{rev}: {branch}, {bookmarks}\n'
  @  5: sebhtml, topic-Z
  |
  | o  4: default, merged-head
  |/|
  | o    3: default,
  | |\
  | | o  2: sebhtml, sebhtml/99992-topic-Y
  | |/
  o |  1: sebhtml, sebhtml/99991-topic-X
  |/
  o  0: default,
  

Multiple revisions under bookmarked head:

  $ hg log -GT '{rev}: {branch}, {bookmarks}\n' -B merged-head
  o    4: default, merged-head
  |\
  | ~
  o    3: default,
  |\
  ~ ~

Follows multiple bookmarks:

  $ hg log -GT '{rev}: {branch}, {bookmarks}\n' -B merged-head -B topic-Z
  @  5: sebhtml, topic-Z
  |
  ~
  o    4: default, merged-head
  |\
  | ~
  o    3: default,
  |\
  ~ ~

Filter by bookmark and branch:

  $ hg log -GT '{rev}: {branch}, {bookmarks}\n' -B merged-head -B topic-Z -b default
  o    4: default, merged-head
  |\
  | ~
  o    3: default,
  |\
  ~ ~


Unknown bookmark:

  $ hg log -B unknown
  abort: bookmark 'unknown' does not exist
  [255]

Shouldn't accept string-matcher syntax:

  $ hg log -B 're:.*'
  abort: bookmark 're:.*' does not exist
  [255]
