Compatibility with 0.7/1.0

[lostella]

Currently tests fail on nightly. Since feature freeze for Julia 1.0 is about to hit, it will be soon time to start making the package forward-compatible. We can use this space to list criticalities and discussions on that regards.

Update - 25/03/2018

I'm currently going through this. General things found so far:

• the Base.LinAlg module is now LinearAlgebra
• Base.A_mul_B! has become LinearAlgebra.mul!
• Base.Ac_mul_B!(y, A, x) is now LinearAlgebra.mul!(y, adjoint(A), x)
• sparse factorizations moved to the SuiteSparse module (from Base.SparseArrays)
• random number generation functions moved to the Random module (from Base)
• @printf moved to the Printf module (from Base)
• warnings are generated when .+ (and similarly for other operators) is not appropriately spaced away from the operands (example: 2.+x confuses the parser on the nature of first summand 2 or 2.0 I guess)
• when broadcast was not explicitly used, e.g. x::AbstractArray + y::Number, now we get a warning
• zeros(a::AbstractArray) is deprecated in favor of zero, fill, fill!
• the old form function f{T}(x::T) ... end now generates warnings, I'm getting rid of these everywhere, in favor of the where notation
• docstrings should be 1 newline away from what they refer to (i.e., no blank line in between, warning otherwise)
• findmax does not work on generator expressions anymore

Package specific issues:

• dspev! and dspevV! are broken
