Rebase from master and fix resulting conflicts. :(

  git pull --rebase
  (fix conflicts manually)
  git add src/IceBuildDefs.h
  git rebase --continue

BTW, for me "make format" is reformatting the version of IceBuildDefs.h in
master, so I guess we forgot to reformat before that last commit?  In any case,
we should take care of that in this CL.
