fix some deprecations

[fredrikekre]

Building the docs on CI results in a huge amount of depwarn again, fixed most of them.

Needs JuliaLang/Compat.jl#452 to pass on julia 0.6

It would be nice with a new release with this and 611aa82 which should silence most of the warnings.

Thanks!

Will do.

Tests pass now, but there was a newer nightly on macOS, which also included some recent find* changes, should be fixed with JuliaLang/Compat.jl#457 so we could either wait for that or merge this and fix that in a separate PR.

Thanks for this! I suspect these deprecations are slowing down the doc build in julia CI quite a bit, so would be good to get this released as soon as possible.

Looks like DocStringExtensions need to be fixed as well?

[fredrikekre]

Yes, I am waiting for JuliaLang/Compat.jl#457 for that

[KristofferC]

Ah, of course. Sorry.

[Keno]

Can we just take the most direct route possible to getting rid of the deprecations, even if that means an ugly hack here? All the deprecation warnings are causing Base CI to time out.

[JeffBezanson]

Seconded. This is now top priority, as it is slowing down Base development quite a bit. In many cases CI times out because of it.

[mortenpi]

The nightly test should pass now. Once it does, I'll merge and tag.
