a368209b1d tracking_collisions.c: initial skeleton. 
... of a program to just test the hashing functions collisions on a 24
bit output with strings that are very likely Redis key names, and names
of a kind that are particularly prone to collisions.

09c06698e9 Client side caching: redis-cli ability to enable tracking. 
This is extremely useful in order to simulate an high load of requests
about different keys, and force Redis to track a lot of informations
about several clients, to simulate real world workloads.

436d02dd7b Move signalFlushedDb() into a better place. 
Now that the call also invalidates client side caching slots, it is
important that after an internal flush operation we both send the
notifications to the clients and, at the same time, are able to reclaim
the memory of the tracking table. This may even fix a few edge cases
related to MULTI/EXEC + WATCH during resync, not sure, but in general
looks more correct.

842b44dc46 Client side caching: call the invalidation functions always. 
Otherwise what happens is that the tracking table will never get garbage
collected if there are no longer clients with tracking enabled.
Now the invalidation function immediately checks if there is any table
allocated, otherwise it returns ASAP, so the overhead when the feature
is not used should be near zero.

bd0f06c18c RDB: handle encoding errors with rdbExitReportCorruptRDB(). 
Without such change, the diskless replicas, when loading RDB files from
the socket will not abort when a broken RDB file gets loaded. This is
potentially unsafe, because right now Redis is not able to guarantee
that encoding errors are safe from the POV of memory corruptions (for
instance the LZF library may not be safe against untrusted data?) so
better to abort when the RDB file we are going to load is corrupted.

Instead I/O errors are still returned to the caller without aborting,
so that in case of short read the diskless replica can try again.

c56b4ddc6f prevent diskless replica from terminating on short read 
now that replica can read rdb directly from the socket, it should avoid exiting
on short read and instead try to re-sync.

this commit tries to have minimal effects on non-diskless rdb reading.
and includes a test that tries to trigger this scenario on various read cases.
