Coming soon: second generation prototype of Hg forest consolidation

[Erik Joelsson]

Hello,

We could certainly take this opportunity to do so. Moving all the files 
around has a pretty big cost in history size in the repository, so when 
doing large moves like this, it's good to get things as right as 
possible in one go.

(Will talk to you about details offline)
