There were two cases outlined in issue #3512 and PR #3551 where
the Geo API returned unexpected results: empty strings where NULL
replies were expected, or a single null reply where an array was
expected. This violates the Redis principle that Redis replies for
existing keys or elements should be indistinguishable.
This is technically an API breakage so will be merged only into 4.0 and
specified in the changelog in the list of breaking compatibilities, even
if it is not very likely that actual code will be affected, hopefully,
since with the past behavior basically there was to acconut for *both*
the possibilities, and the new behavior is always one of the two, but
in a consistent way.

You can still force the logo in the normal logs.
For motivations, check issue #3112. For me the reason is that actually
the logo is nice to have in interactive sessions, but inside the logs
kinda loses its usefulness, but for the ability of users to recognize
restarts easily: for this reason the new startup sequence shows a one
liner ASCII "wave" so that there is still a bit of visual clue.
Startup logging was modified in order to log events in more obvious
ways, and to log more events. Also certain important informations are
now more easy to parse/grep since they are printed in field=value style.
The option --always-show-logo in redis.conf was added, defaulting to no.

This commit also contains other changes in order to conform the code to
the Redis core style, specifically 80 chars max per line, smart
conditionals in the same line:
if (that) do_this();

The new algorithm provides the same speed with a smaller error for
cardinalities in the range 0-100k. Before switching, the new and old
algorithm behavior was studied in details in the context of
issue #3677. You can find a few graphs and motivations there.

Otherwise for small cardinalities the algorithm will output something
like, for example, 4.99 for a candinality of 5, that will be converted
to 4 producing a huge error.
