Add auto device discovery

[santarl]

Instead of adding ip address manually, have it auto detect running instances and offer to connect.

One approach would be to:

• host a mDNS server (or similar service) on the pc side (rust app) and have it broadcast itself
• have the vita detect it send a packet to it with its own ip
• which the rust app accepts and initiates the connection to.

I prefer the above approach instead of having the vita broadcast itself because idk if u can host a mDNS server on vita although that would makes things a lot simpler

hmmmmm

Yes, we can try a Broadcast packet on a network with special content like Heartbeat.

We can only hope that some clever Windows firewall doesn't interfere with this.

On the other hand, it's not exactly safe.

Theoretically, someone could pretend to be a PS Vita device and the client would connect automatically.

There needs to be a mechanism to confirm and warn users so they don't mindlessly accept the first search option while sitting on a public network with 50ms latency xD

we can use some kinda pin like moonlight / sunshine does it for first time.

after that we can have the devices verify themselves with keys ig

FWIW, I was messing with a custom discovery logic based on multicast which would be like the one you suggested with mDNS, because I judged that mDNS would be too much work at the time.
I also wanted to invert the client-server relationship because it makes more sense, but I didn't have the opportunity to do so.
