Merge pull request #36 from tarantool/filonenko-mikhail-patch-1

Update consumer_msg.c

Resolve issues with close and __gc methods

Fixed issues:

• consumer and producer yields in lua __gc meta methods which leads to crash for whole tarantool (?) - fixed by removing lua __gc meta methods and moving it's logic into separate destroy C functions which will be called from lua close methods of Consumer / Producer
• consumer:close sometimes hangs forever - fixed byfollowing changes:
  • now we instantly destroying librdkafka messages on consume in poll thread which prevents rd_kafka_close and rd_kafka_destroy C functions hangs cause of busy resources
  • now lua Consumer stops polling fibers only after librdkafka consumer was closed which prevents non handeled callbacks from closing operation
• producer sometimes hangs forever - updated librdkafka to 1.5.2

Changes:

• static build now working as expected
• added support for rebalance callback to consumer
• moved polling calls to background thread that leads to huge performance improve
