In the FSFS commit code, explicitly pass changed paths data between
functions to make it more obvious how and where the data is used,
and rename some variables for clarity. No functional change.

* subversion/libsvn_fs_fs/transaction.c
  (verify_locks): Add 'changed_paths' parameter, replacing the local
   'changes' variable, and stop fetching the list of changed paths
   in the transaction from within this function. Rename the existing
   'changed_paths' local variable to 'changed_paths_sorted'.
  (commit_body): Fetch changed paths before calling verify_locks()
   and pass changed paths to verify_locks() explicitly.
