Disable all logs by default.
Change default netplay buffer to 5.
JIT: fix RAM check in load-from-constant-address

A bug that seems to have been uncovered by allowing immediate-address loads.
Super Monkey Ball 2 crashes without this change -- it's possible, however, that
the game actually requires the MMU hack, since it crashed due to accessing an
address in the 0x20000000-0x3fffffff range.
Merge pull request #886 from RachelBryk/netplay-buffer

Change default netplay buffer to 5.
Remove the SSE2 messagebox.

This is no longer required since we don't support x86_32 anymore.
x86_64 implies SSE2 support.
Also this check was a bit messed up and was hitting on Generic builds.

Remove the SSE2 messagebox.
JIT64: try enabling dcbz again

This time, check the address carefully beforehand, since apparently some games
do horrible things like running it on non-RAM addresses, or at the very least
virtual addresses.

JIT: revert lmw optimizations

This seems to break Star Wars Rogue Leader and I have no idea why, so for the
meantime I'm just going to revert it since it's not very important.
MMU: fix enhanced BAT support

I don't know what I can test this on, but it was definitely broken before.
Seems to be a few clock cycles faster too due to the refactoring?
