Unfortunately, as outlined by @soloestoy in #4505, "lua" AUX RDB field
loading in case of duplicated script was still broken. This commit fixes
this problem and also a memory leak introduced by the past commit.
Note that now we have a regression test able to duplicate the issue, so
this commit was actually tested against the regression. The original PR
also had a valid fix, but I prefer to hide the details of scripting.c
outside scripting.c, and later "SCRIPT LOAD" should also be able to use
the function luaCreateFunction() instead of redoing the work.

With PSYNC2 to force a full SYNC in tests is hard. With this new DEBUG
subcommand we just need to call it and then CLIENT KILL TYPE master in
the slave.

In the case of slaves loading the RDB from master, or in other similar
cases, the script is already defined, and the function registering the
script should not fail in the assert() call.

It's a bit of black magic without actually tracking it inside rax.c,
however Redis usage of the radix tree for the stream data structure is
quite consistent, so a few magic constants apparently are producing
results that make sense.

Note that streams produced by XADD in previous broken versions having
elements with 4096 bytes or more will be permanently broken and must be
created again from scratch.

After checking with the community via Twitter (here:
https://twitter.com/antirez/status/915130876861788161) the verdict was to
use ":". However I later realized, after users lamented the fact that
it's hard to copy IDs just with double click, that this was the reason
why I moved to "." in the first instance. Fortunately "-", that was the
other option with most votes, also gets selected with double click on
most terminal applications on Linux and MacOS.
So my reasoning was:
1) We can't retain "." because it's actually confusing to newcomers, it
looks like a floating number, people may be tricked into thinking they
can order IDs numerically as floats.
2) Moving to a double-click-to-select format is much better. People will
work with such IDs for long time when coding / debugging. Why making now
a choice that will impact this for the next years?
The only other viable option was "-", and that's what I did. Thanks.

The core of this change is the implementation of stream trimming, and
the resulting MAXLEN option of XADD as a trivial result of having
trimming functionalities. MAXLEN already works but in order to be more
efficient listpack GC should be implemented, currently marked as a TODO
item inside the comments.
