Bug#43254: SQL_SELECT_LIMIT=0 crashes command line client

Browse Source 
When asking what database is selected, client expected
to *always* get an answer from the server.

We now handle failure more gracefully.

See comments in ticket for a discussion of what happens,
and how things interlock.


client/mysql.cc:
  Handle empty result-sets gracefully, as opposed
  to just result sets with n>0 items that may themselves
  be empty.
