Reapply this commit on top of hiredis as a local change. Previosuly it
was pulled from a private hiredis branch, which resulted with it going
away on subtree pull.
The redis-cli command line tool and redis-sentinel service may be vulnerable
to integer overflow when parsing specially crafted large multi-bulk network
replies. This is a result of a vulnerability in the underlying hiredis
library which does not perform an overflow check before calling the calloc()
heap allocation function.
This issue only impacts systems with heap allocators that do not perform their
own overflow checks. Most modern systems do and are therefore not likely to
be affected. Furthermore, by default redis-sentinel uses the jemalloc allocator
which is also not vulnerable.

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.
