[Ovmsdev] Mongoose update & dev merge

[Michael Balzer]

Mark, Steve,

I'm about to update our mongoose submodule to the latest changes _including_ the latest additions to the "dev" branch.

That's because I want to use the mg_broadcast() function, which doesn't work on the ESP32 until this fix from the dev branch:

https://github.com/cesanta/mongoose/commit/780077d1187ff632bdcbf33d65207a084027aba9

Quickly found that in the mongoose issues once I knew what to look for… ;)

My local checkout builds & runs. I've checked through the commits, there is no API change (except a minor one on HTTP header parsing). None of the commits looks
like it could break something and there are some clear fixes included, so I think we can just merge the dev branch.

I'll do some general tests before pushing the change, if you'd like me to wait with the update or do some specific tests, tell me.

Regards,
Michael
