changelog: move branchinfo to changelogrevision

The function parses the extra dictionary after looking up the
changelogrevision. To avoid duplicated look up, it is better to provide
it as property of changelogrevision instead. Keep the function for a
release cycle as at least the topic extension depends on it.

#require pygit2

Setup:
  $ GIT_AUTHOR_NAME='test'; export GIT_AUTHOR_NAME
  > GIT_AUTHOR_EMAIL='[e-mail]'; export GIT_AUTHOR_EMAIL
  > GIT_AUTHOR_DATE="2007-01-01 00:00:00 +0000"; export GIT_AUTHOR_DATE
  > GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"; export GIT_COMMITTER_NAME
  > GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"; export GIT_COMMITTER_EMAIL
  > GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"; export GIT_COMMITTER_DATE
  > count=10
  > gitcommit() {
  >    GIT_AUTHOR_DATE="2007-01-01 00:00:$count +0000";
  >    GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
  >    git commit "$@" >/dev/null 2>/dev/null || echo "git commit error"
  >    count=`expr $count + 1`
  >  }


  $ hg version -v --config extensions.git= | grep '^[E ]'
  Enabled extensions:
    git  internal  (pygit2 *) (glob)

Test auto-loading extension works:
  $ mkdir nogit
  $ cd nogit
  $ mkdir .hg
  $ echo git >> .hg/requires
  $ hg status
  abort: repository specified git format in .hg/requires but has no .git directory
  [255]
  $ git init
  Initialized empty Git repository in $TESTTMP/nogit/.git/
  $ git config --global init.defaultBranch master
This status invocation shows some hg gunk because we didn't use
`hg init --git`, which fixes up .git/info/exclude for us.
  $ hg status
  ? .hg/cache/git-commits.sqlite
  ? .hg/cache/git-commits.sqlite-shm
  ? .hg/cache/git-commits.sqlite-wal
  ? .hg/requires
  $ cd ..

Now globally enable extension for the rest of the test:
  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > git=
  > [git]
  > log-index-cache-miss = yes
  > EOF

Make a new repo with git:
  $ mkdir foo
  $ cd foo
  $ git init
  Initialized empty Git repository in $TESTTMP/foo/.git/
Ignore the .hg directory within git:
  $ echo .hg >> .git/info/exclude
  $ echo alpha > alpha
  $ git add alpha
  $ gitcommit -am 'Add alpha'
  $ echo beta > beta
  $ git add beta
  $ gitcommit -am 'Add beta'
  $ echo gamma > gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Without creating the .hg, hg status fails:
  $ hg status
  abort: no repository found in '$TESTTMP/foo' (.hg not found)
  [10]
But if you run hg init --git, it works:
  $ hg init --git
  $ hg id --traceback
  heads mismatch, rebuilding dagcache
  3d9be8deba43 tip master
  $ hg status
  ? gamma
Log works too:
  $ hg log
  changeset:   1:3d9be8deba43
  bookmark:    master
  tag:         tip
  user:        test <[e-mail]>
  date:        Mon Jan 01 00:00:11 2007 +0000
  summary:     Add beta

  date:        Mon Jan 01 00:00:10 2007 +0000
  summary:     Add alpha
  


and bookmarks:
  $ hg bookmarks
   * master                    1:3d9be8deba43

diff even works transparently in both systems:
  $ echo blah >> alpha
  $ git diff
  diff --git a/alpha b/alpha
  index 4a58007..faed1b7 100644
  --- a/alpha
  +++ b/alpha
  @@ -1* +1,2 @@ (glob)

  +blah
  $ hg diff --git
  diff --git a/alpha b/alpha

  +++ b/alpha
  @@ -1,1 +1,2 @@
   alpha
  +blah

Remove a file, it shows as such:
  $ rm alpha
  $ hg status
  ! alpha
  ? gamma

Revert works:
  $ hg revert alpha --traceback
  $ hg status
  ? gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Add shows sanely in both:
  $ hg add gamma
  $ hg status
  A gamma
  $ hg files
  alpha
  beta
  gamma
  $ git ls-files
  alpha
  beta
  gamma
  $ git status
  On branch master
  Changes to be committed:
    (use "git restore --staged <file>..." to unstage)
  	new file:   gamma
  

forget does what it should as well:
  $ hg forget gamma
  $ hg status
  ? gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

clean up untracked file
  $ rm gamma

hg log FILE

  $ echo a >> alpha
  $ hg ci -m 'more alpha' --traceback --date '1583522787 18000'
  $ echo b >> beta
  $ hg ci -m 'more beta'

  $ echo a >> alpha
  $ hg ci -m 'even more alpha'

  $ hg log -G alpha
