On the fsfs-format7 branch:  Drop the svn_fs_fs__changes_finalize
function as it only complicates the API.  Let
svn_fs_fs__write_changes_container() automatically determine where
to get a finalized path table from.

* subversion/libsvn_fs_fs/changes.h
  (svn_fs_fs__changes_finalize): drop

* subversion/libsvn_fs_fs/changes.c
  (svn_fs_fs__changes_finalize): drop
  (svn_fs_fs__write_changes_container): finialize path table locally
