Fix for bug #19736 VIEW: column names not quoted properly when view is replicated

When we write 'query=...' string to a frm file for views on a slave, 
indentifiers are not properly quoted due to missing OPTION_QUOTE_SHOW_CREATE 
flag in the thd->options.

Fix: properly set thd->options for the slave thread.


mysql-test/r/rpl_view.result:
  Fix for bug #19736 VIEW: column names not quoted properly when view is replicated
    - result adjusted.
sql/slave.cc:
  Fix for bug #19736 VIEW: column names not quoted properly when view is replicated
    - properly set thd->options only in one place (in the set_slave_thread_options()),
      using thd_startup_options. As a side effect we have OPTION_BIG_SELECTS flag set
      after the set_slave_thread_options() call from the 
      log_enevt.cc:Rotate_log_event::exec_event().
