* Adds an indirection to every allocation/deallocation to allow users to plug in ones of their choosing (use custom functions, jemalloc, etc). * Gracefully handle OOM everywhere in hiredis. This should make it possible for users of the library to have more flexibility in how they handle such situations. * Changes `redisReaderTask->elements` from an `int` to a `long long` to prevent a possible overflow when transferring the task elements into a `redisReply`. * Adds a configurable `max elements` member to `redisReader` that defaults to 2^32 - 1. This can be set to "unlimited" by setting the value to zero.
