BK -> git export done

Hi folks,

I managed finally to export the complete kernel history into git format
The resulting number of objects is ~ 500000
The required disk space is ~ 3.2 GiB

We also tracked the blob/tree/commit references in a SQL database. We
will post a SQL dump when the database is in a bit better shape. This
should make history tracking quite simple.

I currently figure out a way to post the data. My poor DSL line is a bit
too slow :)
