I tried using 'svn merge' to do the merge but it did a terrible job and there were bazillions of conflicts. So instead I just took the diff between the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed the added files (no files needed to be 'svn remove'd) and committed. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10156
