Move rectuangular full packed matrix support from base to LinearAlgebra.jl

[andreasnoack]

The methods have never been exported or maintained so it should be safe to move them out of base. This also fixes #11072.

ref JuliaLinearAlgebra/GenericLinearAlgebra.jl@946cb42 - looks like these weren't tested here. If any registered packages are using these, it would be good to register LinearAlgebra and add this to Compat.

👍 This will dramatically improve linalg/lapack.jl's coverage stats and just be better.

[andreasnoack]

@tkelman The package will be registered when I've written some documentation and tests. I'd be very surprised if these functions are used in any package so I'll go ahead a merge this.

A grep can answer that question. @dmbates had asked about them, and it's entirely possible he's not the only person trying to do more exotic operations.

lapack.jl now has 93% test coverage. https://coveralls.io/builds/3047587

I find the coveralls UI completely confusing. I have basically no idea how to, e.g., find what the percentage coverage for that file is from that link.

[StefanKarpinski]

When I did navigate to it (use the search thing), I see 89.02% coverage. Are we looking at the same thing?

[kshyatt]

I swear it was 93% a few minutes ago. Oh well. 89% is still really good.

[StefanKarpinski]

Yes, it's great. This is really getting there.

Is my guide at #11885 not clear enough? Could you suggest improvements?

[StefanKarpinski]

No, your guide is great. I'm really just venting that their UI is lousy.

[kshyatt]

I think it's really cool that I have to click like 10 different things to get the information I want.
