  Partial fix for Issues 7067 and 10434 - std.random.RandomCover

The existing RandomCover design is fatally flawed because it requires a RNG as input, which it then copies internally by value.  So, unless the user is smart enough to pass something like e.g. SomeRNG(unpredictableSeed), there will be unintended correlations in random behaviour.

This partial fix follows the design of RandomSample in allowing RandomCover to use the thread-global default RNG rndGen.  It also improves the choice of template parameter and variable names in line with Issue 10434.

  Partial fix for Issue 10434 - std.random.RandomSample

In line with changes to RandomCover, this patch tweaks
the choice of template parameter and variable names in
order to bring clarity and uniformity to the module.

  Correct the .save methods for RandomCover and RandomSample.

RandomCover and RandomSample should only be save'able if:

   * the input is a forward range

   * the thread-global RNG rndGen is not being used

   * the RNG being used is a forward range.
