revset: optimize not public revset
This patvh speeds up the computation of the not public() changeset
and incidentally speed up the computation of divergents() changeset on our big
repo by 100x from 50% to 0.5% of the time spent in smartlog with evolve.
In this patch we optimize not public() to _notpublic() (new revset) and use
the work on phaseset (from the previous commit) to be able to compute
_notpublic() quickly.
We use a non-lazy approach making the assumption the number of notpublic
change will not be in the order of magnitude of the repo size. Adopting a
lazy approach gives a speedup of 5x (vs 100x) only due to the overhead of the
code for lazy generation.

This test file aims at test topological iteration and the various configuration it can has. $ cat >> $HGRCPATH << EOF > [ui] > logtemplate={rev}\n > EOF On this simple example, all topological branch are displayed in turn until we can finally display 0. this implies skipping from 8 to 3 and coming back to 7 later. $ hg init test01 $ cd test01 $ hg unbundle $TESTDIR/bundles/remote.hg adding changesets adding manifests adding file changes added 9 changesets with 7 changes to 4 files (+1 heads) (run 'hg heads' to see heads, 'hg merge' to merge) $ hg log -G o 8 | | o 7 | | | o 6 | | | o 5 | | | o 4 | | o | 3 | | o | 2 | | o | 1 |/ o 0 (display all nodes) $ hg --config experimental.graph-group-branches=1 log -G o 8 | o 3 | o 2 | o 1 | | o 7 | | | o 6 | | | o 5 | | | o 4 |/ o 0 (revset skipping nodes) $ hg --config experimental.graph-group-branches=1 log -G --rev 'not (2+6)' o 8 | o 3 | o 1 | | o 7 | | | o 5 | | | o 4 |/ o 0 (begin) from the other branch $ hg --config experimental.graph-group-branches=1 --config experimental.graph-group-branches.firstbranch=5 log -G o 7 | o 6 | o 5 | o 4 | | o 8 | | | o 3 | | | o 2 | | | o 1 |/ o 0
