Whitelist SIGUSR1 to avoid auto-triggering errors.
...
This commit fixes issue #875 that was caused by the following events:
1) There is an active child doing BGSAVE.
2) flushall is called (or any other condition that makes Redis killing
the saving child process).
3) An error is sensed by Redis as the child exited with an error (killed
by a singal), that stops accepting write commands until a BGSAVE happens
to be executed with success.
Whitelisting SIGUSR1 and making sure Redis always uses this signal in
order to kill its own children fixes the issue.

TTL API change: TTL returns -2 for non existing keys.
...
The previous behavior was to return -1 if:
1) Existing key but without an expire set.
2) Non existing key.
Now the second case is handled in a different, and TTL will return -2
if the key does not exist at all.
PTTL follows the same behavior as well.

Make sure that SELECT argument is an integer or return an error.
...
Unfortunately we had still the lame atoi() without any error checking in
place, so "SELECT foo" would work as "SELECT 0". This was not an huge
problem per se but some people expected that DB can be strings and not
just numbers, and without errors you get the feeling that they can be
numbers, but not the behavior.
Now getLongFromObjectOrReply() is used as almost everybody else across
the code, generating an error if the number is not an integer or
overflows the long type.
Thanks to @mipearson for reporting that on Twitter.

Use safe dictionary iterator from KEYS
...
Every matched key in a KEYS call is checked for expiration. When the key
is set to expire, the call to `getExpire` will assert that the key also
exists in the main dictionary. This in turn causes a rehashing step to
be executed. Rehashing a dictionary when there is an iterator active may
result in the iterator emitting duplicate entries, or not emitting some
entries at all. By using a safe iterator, the rehash step is omitted.
