annotate: reuse ancestry context when adjusting linkrev (issue4532)
The linkrev adjustment will likely do the same ancestry walking multiple time
so we already have an optional mechanism to take advantage of this. Since
2896f53509a7, linkrev adjustment was done lazily to prevent too bad performance
impact on rename computation. However, this laziness created a quadratic
situation in 'annotate'.
Mercurial repo: hg annotate mercurial/commands.py
before: 8.090
after: 36.300
Mozilla repo: hg annotate layout/generic/nsTextFrame.cpp
before: 1.190
after: 290.230
So we setup sharing of the ancestry context in the annotate case too. Linkrev
adjustment still have an impact but it a much more sensible one.
