43a2d0286b Fix range of values generated by uniform real dist 
Now generated floating-point values are uniformly distributed
on the interval [a, b). Before this commit it was possible
to produce values equal to b.

6d5d9b0b5d Now radix_sort_by_key is stable 
Radix sort algorithm was not stable when used for
sorting by key in descending order (see issue #588).

d4653c6624 Use nextafter to push values down into [0,1) range 
Without this, we can get values of 1, but that leads to negative
infinity from the following log; if we push the x1 value towards 0, we
ensure that (one-x1) is always a value in (0,1], and so the log value
will be in (-inf, 0], which is what we want.

2eed2c2fdd Provide wait_list::reserve() method 
This should help to get rid on unnecessary heap allocations.

The wait lists are usually small, which means that just pushing back
elements without prior call to reserve has very high chance of hitting
capacity limit every time wait_list::insert is called.

73ef474fdd Add stable_sort_by_key() 
Currently, stable_sort_by_key() works on GPUs only for
keys that are radix-sortable and for very small inputs.

6b34c63fb8 Fix kernels in reduce_by_key_with_scane.hpp 
It was not guaranteed that every barrier would be encountered by all
work-items in a work-group executing the kernels due to some work-items
returing too early, not entering the conditional if with with a barrier
or not executing every iteration of the loop with a barrier.
