Tunable timeout parameter for MQCONN/MQCONNX

In MQ 7.1, MQ client can use followed 2 timeout mechanism to keep SVRCONN channel alive
1. Connect_Timeout set in mqclient.ini to monitor tcp connection/handshaking timeout
2. After connection (from mq view), HBINT can keep monitoring

however, between 'socket connection establish' & 'mq connection establish', there's a gap mq client waiting qmgr response via select(), from PMR, mq client is using ccxSetTimeOut and hardcoded 180 seconds

Cust ask 'tunable' parameter for this 'hardcoded' 180 seconds timeout at this moment in order to let client can get error return in control-able specified timeout period

    We will consider this for a future release.

    However, we believe this customer has been informed incorrectly in their PMR that the timeout is hardcoded: it is not fixed at 180, but can be overridden by MQRCVBLKTO per APAR IC46074 http://www-01.ibm.com/support/docview.wss?uid=swg1IC46074
