No wonder I never got mixed declaration and code warnings.

Doing this way because I have no idea if the GP2X port was SUPPOSED to use SDL or not in the first place

Added a SDL12=1 flag to all ports whose interface code still lives in the sdl12 folder (and is unsupported by SDL 2.0 officially anyway)

This basically causes the makefile to use the sdl12 folder instead of the main sdl folder

This reverts commit 8607f524, reversing
changes made to 11d76a65.

The code in i_net.c doesn't actually seem to be used in SRB2. I was able to compile a build without it, and hosting and joining netgames worked just fine (well, as fine as they can with the current state of the netcode...).

Do we really need to keep it around? If not, I say get rid of it. It seems like useless clutter that is just going to confuse people who are trying to understand the source code.

SDL1.2 is dead, long live SDL
