Redis hangs or misbehaves when processing multibulk redis responses (nested arrays)
Solution
Keep track of how many more elements need to be parsed when parsing the redis response,
as well as whether the top-level value is a multi-bulk response
Continue to properly count the number of top level array elements for request types that can be fragmented such as multi-gets
Result
twemproxy will now be able to proxy results of eval and other commands when they return nested arrays
(this will help in implementing command and georadiuswithcoord. commands in the future)
