Consider moving from winapi to windows-sys

[workingjubilee]

This is like #535 except it is asking a slightly different question but with the same goal: would migrating from winapi offer a more maintainable crate? If so, we should probably do it.

I believe @kennykerr was doing some work on this previously: #494

I think it's about time if everyone is in agreement - there were some questions in #494 but the std library has since moved to windows-rs as @alexcrichton suggested thanks to @ChrisDenton and the libs have been working reliably so I would image the concerns that @thomcc had would be satisfied.

I'd recommend getting that solved first, effectively deleting library/std/src/sys/windows/c.rs, and then once that's migrated this should be able to trivially follow.

Yeah I remember reviewing some of the PRs that were part of that cleanup.

I'm game to see that PR rebased and reopened, if you would like.

I just started looking at this. We currently use our own definitions and have a whole nest of macros to confirm they match the ones in the winapi crate (with exceptions for known issues). windows-bindgen (soon riddle) allows generating bindings so we can greatly simplify things here.

I'm currently looking into modifying the debuginfo search path so that PDBs next to the binary can be found. Being able to use windows-sys would greatly simplify that task, I think.

The winapi crate was replaced in #634. Should this issue be closed now?

[workingjubilee]

Yes! Thanks @CraftSpider!
