Just the sceUtility changes from ANR2ME's branch

[hrydgard]

Added the SSID and ConfigName strings from sceNet too.

From anr2me#21

See #19812

@anr2me fyi

[hrydgard]

Actually I think I'll pick the config changes too into this PR so you can set the DNS.

[hrydgard]

Hm, what's the 135.148.144.253 that we default to?

[ChaCheeChoo]

I think that was the old PS Rewired DNS
their new one is 67.222.156.250

[hrydgard]

thanks, I'll switch to that.

[hrydgard]

OK, hopefully I got all the important DNS / Apctl-related stuff now... also added a simple UI to set the primary/secondary DNS.

Probably for GameSpy games, according to this https://www.reddit.com/r/PSP/comments/pwf745/some_gamespy_related_games_work_online_right_now/
Not sure whether it's still active or not.

PS Rewired has redirects to OpenSpy on their DNS so using it should still be fine for those.

[hrydgard]

Cool.

Later I guess we can have a drop down of different known DNSs... should probably download the list from ppsspp.org/dns.json or something.
