This gets us everything we need (I hope!) to support 16-bit code in LX binaries and call into 16-bit OS/2 APIs. This is just enough to call into VioGetMode() (which isn't otherwise implemented yet) as an example. If this is ever used Winelib-style to provide an OS/2 API to native Linux binaries, the 16-bit system APIs are 32-bit clean and C callable, as one might expect them to be. All the tapdancing is to support existing LX binaries in the loader and bridge between the 32-bit clean APIs and existing 16-bit code that expects to call 16-bit APIs. This was a staggering amount of effort, but yay! Other fixes and improvements probably leaked into this commit, as a lot of code got touched and a lot of research and debugging took place.
