hiredis: Update to latest version

Browse Source 
This is hiredis f225c276be7fd0646019b51023e3f41566633dfe

This update includes all changes that diverged inside of Redis since
the last update.  This version also allows optional source address
binding for connections which we need for some Sentinel deployments.

### 0.11.0
* Increase the maximum multi-bulk reply depth to 7.
* Increase the read buffer size from 2k to 16k.
* Use poll(2) instead of select(2) to support large fds (>= 1024).
### 0.10.1
* Makefile overhaul. Important to check out if you override one or more

The parser limits the level of nesting for multi bulk payloads to 7. If the
multi bulk nesting level is higher than this, the parser returns an error.
