unbundle: faster computation of changed heads

To compute the set of changed heads it's sufficient to look at the recent commits,
instead of looking at all heads currently in existence.

Test that a strip will preserve unrelated changeset archived
------------------------------------------------------------

prepare a suitable tree

  $ echo foo > bar
  $ hg add bar
  $ hg commit -m 'some more commit'
  $ hg log -G --hidden -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  @  3 f90bf4e57854 [draft] some more commit
  |
  o  2 d1e73e428f29 [draft] unbundletesting
  |
  | o  1 883aadbbf309 [draft] unbundletesting
  |/
  o  0 c1863a3840c6 [draft] root
  
  $ hg strip --soft --rev '.'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  saved backup bundle to $TESTTMP/repo/.hg/strip-backup/f90bf4e57854-56b37ff2-backup.hg
  $ hg log -G --hidden -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  o  3 f90bf4e57854 [archived] some more commit

Strips the other (lower rev-num) head

  $ hg strip --rev 'min(head() and not .)'
  saved backup bundle to $TESTTMP/repo/.hg/strip-backup/883aadbbf309-efc55adc-backup.hg

The archived changeset should still be hidden

  $ hg log -G -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  @  1 d1e73e428f29 [draft] unbundletesting
  |
  o  0 c1863a3840c6 [draft] root
  

It may still be around:

  $ hg log --hidden -G -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  o  2 f90bf4e57854 [archived] some more commit
  |
  @  1 d1e73e428f29 [draft] unbundletesting

  o  0 c1863a3840c6 [draft] root
