This upstream patch (r1672295) is needed to fix a test failure when built
against sqlite 3.8.9.  See:

r1672295 | rhuijben | 2015-04-09 07:31:12 -0400 (Thu, 09 Apr 2015) | 15 lines

Optimize STMT_SELECT_EXTERNALS_DEFINED when using Sqlite 3.8.9, by
adding two more rows to the sqlite_stat1 table.

This fixes a test failure in wc-queries-test.c, but actual users most
likely don't notice a difference as a tablescan on an EXTERNALS tables
index is not that expensive, given that most working copies don't have
many externals.

* subversion/libsvn_wc/wc-metadata.sql
  (STMT_INSTALL_SCHEMA_STATISTICS): Add two rows.

* subversion/tests/libsvn_wc/wc-queries-test.c
  (test_schema_statistics): Add a dummy externals row to allow
    verifying schema.
