In environments with load balancers or proxies, the audit plugin logs
only the IP address, making it difficult to differentiate individual client
connections from the same IP.
Add a new 'port' field to the appropriate event objects to capture the
client's TCP port number. Populate the port field with thd->port in the
appropriate functions. The audit plugin receives and logs this port field
along with other connection information, enabling better identification
of individual client connections.

This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
