745ace87e5 rand_distr: Fix dirichlet sample method for small alpha. 
Generating Dirichlet samples using the method based on samples from
the gamma distribution can result in samples being nan if all the
values in alpha are sufficiently small.  The fix is to instead use
the method based on the marginal distributions being the beta
distribution (i.e. the "stick breaking" method) when all values in
alpha are small.

rand: fix incorrect example in Uniform 
The current example to implement `SampleUniform` for custom types is incorrect.
It mistakenly forwards the implementation of `UniformSampler::new_inclusive` to
`UniformSampler::new`.

6e6cc35d99 rand_chacha: improve little-endian performance incrementing pos counter 
On little-endian platforms we can use native vector operations to
increment the pos counter, because it is packed little-endian into the
state vector.
