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().

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.

on ci.redis.io the test fails a lot, reporting that bgsave didn't end.
increaseing the timeout we wait for that bgsave to get aborted.
in addition to that, i also verify that it indeed got aborted by
checking that the save counter wasn't reset.
add another test to verify that a successful bgsave indeed resets the
change counter.

this code is in use only if the master is disk-based, and the replica is
diskless. In this case we use a buffered reader, but we must avoid reading
past the rdb file, into the command stream. which Luckly rdb.c doesn't
really attempt to do (it knows how much it should read).
When rioConnRead detects that the extra buffering attempt reaches beyond
the read limit it should read less, but if the caller actually requested
more, then it should return with an error rather than a short read. the
bug would have resulted in short read.
in order to fix it, the code must consider the real requested size, and
not the extra buffering size.
