    M tests/test-ovsdb.c

  Log Message:
  ovsdb-idl: Adjust indexes during transactions.

When transactions modified tables with indexes, the indexes were not
properly updated to reflect the changes.  For deleted rows, in particular,
this could cause use-after-free errors.

This commit fixes the problem and adds some simple test cases provided by
Han Zhou that, without the fix, cause a crash.
