Switch jdk7u development to Git/Skara

[Andrew Brygin]

Hello Erik,

  I apologize for the really delayed response.

  It seems to be natural to follow the jdk8u migration
  schedule, as it is the main source of changes for jdk7u.
  So, a coordinated migration to consolidated Mercurial
  repositories seems to be most convenient approach.

  As jdk7u has (to put it mildly) a bit less active development,
  we seems to have more freedom regarding the migration schedule.

  So, a two-step  migration to the consolidated Mercurial repo
  in December, and move to the Git repo in February seems to be
  acceptable schedule.

  As I can see, the consolidated prototype [1] already contains
  all changes for the jdk7u forest, and corresponds to the jdk8u
  consolidated repo in the common part of the history.

  From your perspective, is it feasible to migrate to the consolidated
  Mercurial repository during the next week of December (12/06 - 12/12)?

Thanks,
Andrew
