Change the order of the arguments of svn_stream_span() to be consistent
with the other generic stream functions.

* subversion/include/svn_io.h
  (svn_stream_span): Put the 'stream' argument first.

* subversion/tests/libsvn_subr/stream-test.c,
  subversion/libsvn_subr/stream.c,
  subversion/libsvn_subr/subst.c: : Update implementations and usage.
