b8286d1fc9 Changes command stats iteration to being dict-based 
With the addition of modules, looping over the redisCommandTable
misses any added commands. By moving to dictionary iteration this
is resolved.

ffefc9f92d Fix modules blocking commands awake delay. 
If a thread unblocks a client blocked in a module command, by using the
RedisMdoule_UnblockClient() API, the event loop may not be awaken until
the next timeout of the multiplexing API or the next unrelated I/O
operation on other clients. We actually want the client to be served
ASAP, so a mechanism is needed in order for the unblocking API to inform
Redis that there is a client to serve ASAP.

This commit fixes the issue using the old trick of the pipe: when a
client needs to be unblocked, a byte is written in a pipe. When we run
the list of clients blocked in modules, we consume all the bytes
written in the pipe. Writes and reads are performed inside the context
of the mutex, so no race is possible in which we consume the bytes that
are actually related to an awake request for a client that should still
be put into the list of clients to unblock.

It was verified that after the fix the server handles the blocked
clients with the expected short delay.

Thanks to @dvirsky for understanding there was such a problem and
reporting it.
