[Ovmsdev] ESP-IDF v4 / v5 - baby steps

You're certainly right : WolfSSH writes here
https://github.com/wolfSSL/wolfssh : "wolfSSH is dependent on wolfCrypt,
found as a part of wolfSSL".
So it seems we need to bundle it still, and it's a good thing we managed
to have it more or less compile with ESP-IDF 5+ (a few bugs are still
being ironed out - especially the OPENSSL compatibility layer, which may
not be used if mongoose does use mbedTLS instead).
Regarding the integration, I tried (my best :-)) to have it build on
both ESP-IDF 3, ESP-IDF 5 (and also ESP-IDF 4 with a small patch to the
ESP-IDF build system itself). Of course I need help for testing /
reproducing the builds and I'm grateful to those of you sparing some
time to do exactly that.
I have another round of PRs waiting for some peer-review :
-> @List, do not hesitate to have a look - especially for the ones that
are a little bit touchy:
is trying to guess whether the multiple switch case falls-through
are wanted, or not. It impacts the code of multiple people, so it
would be interesting if those people could have a look at it.
is also a big piece and would benefit from a peer-review.
Thanks in advance !
