[RFC PATCH] PE conversion for dinput.dll and dinput8.dll

[Rémi Bernon]

Hi!

It seems like converting things to PE is all the rage these days, so I 
thought I could give it a try too. I don't know any application or games 
that requires dinput or dinput8 to be PE dlls, but I guess it wouldn't 
hurt any either.

I did a PE + unix lib split, but apparently there were some plans to 
re-implement it over HID, so I'm just sending this as RFC, to see if 
there's any interest in it, or if the HID path is preferred.

IMHO the HID path is much more work, so clearly not something achievable 
short term, and will possibly cause some feature regression. For 
instance the macos forcefeedback seems pretty straightforward to map to 
dinput and would be a shame to port over HID. Also HID is complicated 
add will add a lot of intermediate layers. The it can always be done in 
parallel or in addition to this split.

I tried to make sure the unit tests as well as joy.cpl reported 
identical results, with an X-Box and a DualShock 4 gamepads, but I don't 
have any more specific joysticks to test with. For macos I just made 
sure that it builds, hopefully every single commit although I only 
checked the whole series.

The series is quite long so I'm just attaching it as a single file that 
git am can split.

Cheers,
