instead of APR files.

* subversion/include/svn_client.h: Include svn_io.h for svn_stream_t.
  (svn_client_patch_stream): Read the patch from a stream instead of a file.
* subversion/include/svn_diff.h
  (svn_diff_patch_parser_create): Likewise, read the patch from a stream.

* subversion/libsvn_client/patch.c: Do not include svn_io.h.
  (svn_client_patch): Forward to svn_client_patch_stream() and remove
   the parameter checks that are repeated there.
  (svn_client_patch_stream): Read the patch from a stream instead of a file.

* subversion/libsvn_diff/parse-diff.c: Include svn_io_private.h (temporary).
  (svn_diff_patch_parser_create): Read the patch from a stream, etc.
   For now, just unwrap the underlying APR file from the stream.
  (svn_patch_file_t): Replace the apr_file member with a stream.
  (svn_diff_open_patch_file): Read the patch from a stream, yet again.
  (svn_diff_close_patch_file): Close the stream.

* subversion/tests/libsvn_client/client-test.c
  (test_patch): Open a stream for svn_client_patch_stream.
