range(start, stop) without kwargs accidentally allowed

	if VERSION < v"1.1.0-DEV.506"
	range(start, stop; kwargs...) = range(start; stop=stop, kwargs...)
	end

So before 1.1.0-DEV.506, range(start, stop) will become range(start, stop=stop), which works, using a default step of 1. On 1.1.0-DEV.506 or later, the Base definition of range(start, stop) errors, requiring step or length to be specified. Unfortunately, ONNX.jl already makes use of the range(start, stop) form, making it at preset incompatible with the upcoming julia-1.1.0 (ref. JuliaLang/julia#30374 (comment)).

Not sure what to do here. In the long run, we should make range(start, stop) error on 1.0, too, but that would be a breaking change. (Altough, we nowhere claim it to work, so one might argue it's really a bugfix). In the short term... Should we override the Base method to allow range(start, stop)? That feels so ... wrong.

So the plan is to

• override the Base method to allow range(start, stop) (Always define range(start, stop) #642)
• tag a release (Tag Compat.jl v1.5.0 METADATA.jl#20868)
• deprecate range(start, stop) (and, while at it, remove old deprecations and deprecate any other stuff where Compat has diverged from Base, if any) (Remove old deprecations, deprecate obsolete stuff #646)
• tag a breaking (i.e. major) release.
