bug #1004 : remove the inaccurate "sequential" path for LinSpaced, mark respective function as deprecated, and enforce strict interpolation of the higher range using a correction term.
...
Now, even with floating point precision, both the 'low' and 'high' bounds are exactly reproduced at i=0 and i=size-1 respectively.

bug #698 : rewrite LinSpaced for integer scalar types to avoid overflow and guarantee an even spacing when possible.
...
Otherwise, the "high" bound is implicitly lowered to the largest value allowing for an even distribution.
This changeset also disable vectorization for this integer path.

bug #1286 : automatically detect the available prototypes of functors passed to CwiseNullaryExpr such that functors have only to implement the operators that matters among:
...
operator()()
operator()(i)
operator()(i,j)
Linear access is also automatically detected based on the availability of operator()(i,j).
