/*
Connect to a server doing several retries if needed.
SYNOPSIS
safe_connect()
con - connection structure to be used
host, user, pass, - connection parameters
db, port, sock
NOTE
This function will try to connect to the given server MAX_CON_TRIES
times and sleep CON_RETRY_SLEEP seconds between attempts before
finally giving up. This helps in situation when the client starts
before the server (which happens sometimes).
It will ignore any errors during these retries. One should use
connect_n_handle_errors() if he expects a connection error and wants
handle as if it was an error from a usual statement.
RETURN VALUE
0 - success, non-0 - failure

/*
Connect to a server and handle connection errors in case when they occur.
SYNOPSIS
connect_n_handle_errors()
q - context of connect "query" (command)
con - connection structure to be used
host, user, pass, - connection parameters
db, port, sock
create_conn - out parameter, set to zero if connection was
not established and is not touched otherwise
DESCRIPTION
This function will try to establish a connection to server and handle
possible errors in the same manner as if "connect" was usual SQL-statement
(If error is expected it will ignore it once it occurs and log the
"statement" to the query log).
Unlike safe_connect() it won't do several attempts.

0 - success, non-0 - failure
