Review request for kafka.
Bugs: KAFKA-1933
https://issues.apache.org/jira/browse/KAFKA-1933
Repository: kafka
Description
-------
This patch adds finer locking when appending to log. It breaks
global append lock into 2 sequential and 1 parallel phase.
Basic idea is to allow every thread to "reserve" offsets in non
overlapping ranges, then do compression in parallel and then
"commit" write to log in the same order offsets where reserved.
