This version of hiredis merges modifications of the Redis fork with
latest changes in the hiredis repository.

The same version was pushed on the hiredis repository and will probably
merged into the master branch in short time.

Applied a few modifications to hiredis to tune it for speed (redis-benchmark) and ability to read more deeply nested replies (redis-cli).

to 16k, request buffer size is no longer destroyed when emtpy and large
(better fix needed). Redis clients static output buffer set to 16k as
well.

quick and dirty fix for hiredis bug creating problem with the new redis-cli connect commmand. Also change prompt when redis-cli is not connected
