Fix Issue #5240: faster std.random.uniform for [0.0, 1.0) range

Following typical design in other languages, the function is named
uniform01.  It can be templated on floating-point type, defaulting
to double if none is specified.

The implementation is pretty much derived from its counterpart in
Boost.Random, in particular in its taking account of the different
requirements for integral versus floating-point RNG values, and in
checking that the generated variate is less than 1 before returning.
This last check is necessary simply because we can't guarantee, in
the case of a floating-point based RNG, that we will not get a
result exactly equal to 1.

Mark methods for random number generators in std.random as safe pure nothrow
Add asserts in Copy (and remove an enforce)

Adding extra asserts always helps. As for the enforce, I'm unsure why it was there in the first place: All the other branches simply make the assumption the target is large enough.
Small optimization to uniform01

Only need to chech u < 1 if RNG returns non-integral variates.

Split the overly long sentence in two, otherwise
it's easy to miss the point about auto-generation.
