There was a bug that randomly after opening and closing the menu, some players on Bizhawk would get old items again. Tracking this down took multiple hours over the course of several weeks. The root cause turned out to be reading from the System Bus domain while an DMA copy was happening. Doing so is undefined behavior on GBC (though I'm sure some game relies on it). On Gambatte, you end up reading some garbage byte no matter what the read is (unsure what the providence of the byte is - some garbage, some register, the actual DMA data, who knows?). Normally, this isn't an issue, as Bizhawk callbacks only happen during vblank/halt, which is generally a state where we have valid WRAM to read from. However - a setting is being passed around the community for Bizhawk that changes the frame counter to go from "only when Vblank happens" to "whenever some number of audio samples have happened" which causes the bizhawk callbacks to happen....nearly whenever. Including during a DMA. You can tell this is happening if you print the `PC` register when reading memory - if it matches `FFXX` then you are executing in a routine in HRAM and likely doing a DMA.
Additionally, the check items counter specifically is in WRAM Bank 1 which could be swapped out of - will have to keep an eye on this - generally LADX lives in Bank 1, but there are a few things that use the other banks (swap space for some objects??). This could be a problem on any platform - if we get more reports of bad items gets, that's probably why.
Also, fixes some logging that was never getting reenabled.

This is a Lua script for BizHawk that implements the relevant parts of
the RetroArch networking API used by the Archipelago LADX Client.
socket.lua and core.dll are exact copies of the same files in
data/lua/OOT and various other folders. There is a PR consolidating
these into the base folder, which this commit is anticipating.
LADX "just works"(tm) when this is loaded in Bizhawk.
