WIP: support julia 0.7

[bjarthur]

fixes https://github.com/JaneliaSciComp/NIDAQ.jl/issues/13

[Cody-G]

I'm just wondering how this is going? If it seems like you'll need a few more days then I'll start from this branch and try wrapping the headers with Clang tomorrow (I'm in a bit of a time crunch unfortunately).

[bjarthur]

go for it. i won't have time for awhile.

[Cody-G]

So I've made some progress on this, and I've done a bit of manual editing of Clang's output files to fix some issues. However Clang is still skipping a lot of stuff, and my understanding is that this is expected because it (and Julia) doesn't handle varargs C functions well?

I searched for a couple of these skipped functions in the code for the last version of NIDAQmx that you wrapped, and I didn't get any hits. So maybe it's harmless to skip these functions? I'll try running tests anyway and see, but any guidance you have is appreciated (I haven't used Clang before).

[bjarthur]

clang can be quite difficult. thanks for taking a stab at this.

if the tests pass, and you don't find any problems in your use case, i'd say it's good to go. the only guidance i can offer is here. please update this section of the README with any tips you find noteworthy.

i suspect that there will be more depwarns to fix as femtocleaner doesn't get them all.

[Cody-G]

Thanks! The manual edits turned out to be just as you listed, and I now have tests passing with a USB device. I'll still test some more before we merge, see #15. It was painful, not really because of Clang but because I spent a whole day trying to understand a mysterious error that in the end was fixed by rebooting Windows. And also the instructions for building Julia on Windows were out-of-date. And also BinaryProvider.jl needed patches for Windows.
