phases: use revision number in new_heads

All graph operations will be done using revision numbers, so passing nodes only
means they will eventually get converted to revision numbers internally.

As part of an effort to align the code on using revision number we make the
`phases.newheads` function operated on revision number, taking them as input
and using them in returns, instead of the node-id it used to consume and
produce.

This is part of multiple changesets effort to translate more part of the logic,
but is done step by step to facilitate the identification of issue that might
arise in mercurial core and extensions.

To make the change simpler to handle for third party extensions, we also rename
the function, using a more modern form. This will help detecting the different
between the node-id version and the rev-num version.

I also take this as an opportunity to add some comment about possible
performance improvement for the future. They don't matter too much now, but they
are worse exploring in a while.

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
  [10]

Shouldn't accept string-matcher syntax:

  $ hg log -B 're:.*'
  abort: bookmark 're:.*' does not exist
  [10]
