This introduces winbits.[ch] in the engine, containing layer-independent code migrated from winlayer, including nedmalloc, ebacktrace1, OS version detection, and high-resolution profiling timers.
sdlayer has been expanded to include the code from winbits under _WIN32.
All uses of RENDERTYPEWIN in the source have been examined and changed to _WIN32 (or removed) where the block in question is layer-independent.

This needs improvements to bring it up to par with winlayer, but it is functional. In particular, a good amount of code from winlayer could be used for both layers, including the profiling timers, the version printing code, and the hInstance and hModule sharing.
Known problems: the mouse cursor is not trapped, and the game starts before the startup window shows options.

That is, everyplace a user input is to be converted. The only remaining
instance of atoi() is now atoi(s_buildDate).
