patches for DInput and getting memory size when running FreeBSD

[Olivier Houchard <doginou@ciO.rg>]

Hi,

Here are a few patches.
The first one is to be applied on dlls/dinput/keyboard/main.c. It is ugly but that's the only way I found to get games that use SetEventNotification for keyboard to work.
The second one is to be applied on memory/global.c. It is not the best way to get memory size on FreeBSD I guess, but it is still better than 16*1024*1024 :)
Thanks for reviewing.
