Syntax: `ZMSCORE KEY MEMBER [MEMBER ...]`
This is an extension of #2359
amended by Tyson Andre to work with the changed unstable API,
add more tests, and consistently return an array.
- It seemed as if it would be more likely to get reviewed
after updating the implementation.
Currently, multi commands or lua scripting to call zscore multiple times
would almost definitely be less efficient than a native ZMSCORE
for the following reasons:
- Need to fetch the set from the string every time instead of reusing the C
pointer.
- Using pipelining or multi-commands would result in more bytes sent by
the client for the repeated `ZMSCORE KEY` sections.
- Need to specially encode the data and decode it from the client
for lua-based solutions.
- The fastest solution I've seen for large sets(thousands or millions)
involves lua and a variadic ZADD, then a ZINTERSECT, then a ZRANGE 0 -1,
then UNLINK of a temporary set (or lua). This is still inefficient.

The Redis sentinel would crash with a segfault after a few minutes
because it tried to read from a page without read permissions. Check up
front whether the sds is long enough to contain redis:slave or
redis:master before memcmp() as is done everywhere else in
sentinelRefreshInstanceInfo().
Bug report and commit message from Theo Buehler. Fix from Nam Nguyen.

valsize was not modified during the for loop below instead of getting from c->argv[4], therefore there is no need to put inside the for loop.. Moreover, putting the check outside loop will also avoid memory leaking, decrRefCount(key) should be called in the original code if we put the check in for loop

The connection API may create an accepted connection object in an error
state, and callers are expected to check it before attempting to use it.

- the test now waits for specific set of log messages rather than wait for
timeout looking for just one message.
- we don't wanna sample the current length of the log after an action, due
to a race, we need to start the search from the line number of the last
message we where waiting for.
- when attempting to trigger a full sync, use multi-exec to avoid a race
where the replica manages to re-connect before we completed the set of
actions that should force a full sync.
- fix verify_log_message which was broken and unused

Initialize and configure OpenSSL even when tls-port is not used, because
we may still have tls-cluster or tls-replication.
Also, make sure to reconfigure OpenSSL when these parameters are changed
as TLS could have been enabled for the first time.
