[RFC] 16 bit functions

[Dimitrie O. Paun]

Hi folks,

I was just thinking that it would be nice if a we had a simple
naming rule for 16 bit functions:

"A function is 16 bit if and only if it's name ends in 16."

This way, we can have more reliable tools for detecting
32-16 bit cross calls (unfortunately, winapi_check fails
in many instances for this check).

Most 16 bit functions already adhere to this naming convention,
but there are still a few that don't. Alexandre, would renaming
such functions be acceptable? If so, I can add yet another
janitorial task...
