All library API functions call sendPacket to send an entire MQTT packet over the network.
With the addition of a send timeout (with MQTT_SEND_RETRY_TIMEOUT_MS configuration) in PR #124, the APIs should detect partial packet (or zero bytes) transmission as send failures.

This PR updates the MQTT_Connect, MQTT_Disconnect, MQTT_Subscribe, MQTT_Unsubscibe and MQTT_Ping API functions to return MQTTSendFailed for partial packet transmissions.

Note: The MQTT_Publish function was updated for the same already in PR#124
