Apurva Mehta	bdf4cba047	KAFKA-4817; Add idempotent producer semantics This is from the KIP-98 proposal. The main points of discussion surround the correctness logic, particularly the Log class where incoming entries are validated and duplicates are dropped, and also the producer error handling to ensure that the semantics are sound from the users point of view. There is some subtlety in the idempotent producer semantics. This patch only guarantees idempotent production upto the point where an error has to be returned to the user. Once we hit a such a non-recoverable error, we can no longer guarantee message ordering nor idempotence without additional logic at the application level. In particular, if an application wants guaranteed message order without duplicates, then it needs to do the following in the error callback: 1. Close the producer so that no queued batches are sent. This is important for guaranteeing ordering. 2. Read the tail of the log to inspect the last message committed. This is important for avoiding duplicates.

Ismael Juma	4e7db39556	MINOR: Make indenting in `checkstyle.xml` and `import-control.xml` consistent They now both use 2 spaces for indents, which is what `checkstyle.xml` was already doing. `import.xml` had a mixture of tabs and 4 spaces previously.
