preparing 2.6.10

[Andres Salomon]

Alright, enough people are bothering me for 2.6.10 that we should probably
get it into sid.  I've committed a bunch of bk backports to the svn 2.6.10
k-s directory (small, obvious fixes for the most part); I'm going to aim
for uploading 2.6.10 into NEW either Wed. or Thurs. unless anyone has
objections.
