Davi Arnaut 96e02e5716 Bug#33899: Deadlock in mysql_real_query with shared memory connections ...

The problem is that the read and write methods of the shared
memory transport (protocol) didn't react to asynchronous close
events, which could lead to a lock up as the client would wait
(until time out) for a server response that will never come.

The solution is to also wait for close events while waiting
for I/O from or to the server.

mysql-test/r/shm.result:
  Add test case result for Bug#33899
mysql-test/t/shm.test:
  Add test case for Bug#33899
vio/viosocket.c:
  Also wait for close events.
