netplay fixes from simple64

loganmc10 commented 11 months ago

This is an upstreaming of the netplay code in simple64.

Notably:

rdram_size needs to be set after netplay_sync_settings, so that it has the proper value for disable_extra_mem
main_speedlimiter_toggle should be disabled when netplay is active
A new packet type is added, UDP_RECEIVE_KEY_INFO_GRATUITOUS, which is when the server sends input data without being asked by the player.
Currently, the system checks for desyncs every second. Now, it is every 10 seconds (done in order to reduce network traffic, it's not really important to detect desyncs that quickly)

cc @fzurita , I believe mupen64plus-ae is the only other frontend that makes use of this currently.

Ping @richard42 I think this should be ok to merge

mupen64plus / mupen64plus-core
