004ce96368 Unittests for randomSample being passed an InputRange. 
The assignment of _input = input has been moved from
initialize() to the constructors so as to avoid
problems with nested structs.

cbdd14b57b Issue 10265 - RandomSample fails when passed an InputRange as input 
* Issue fixed by making presence of save() property conditional
   on input being a ForwardRange.

a47707a197 Rewrite of RandomSample to use Jeffrey Scott Vitter's Algorithm D. 
This algorithm calculates a random sample of size n in O(n) time,
generating O(n) random variates, as opposed to the previously
implemented Algorithm S where both scale with the size of the
data being sampled.

Variable names in the implementation follow those in Vitter's
papers introducing the algorithm:

  * Vitter, J. S. (1984) Faster methods for random sampling.
    Commun. ACM 27(7): 703--718.

  * Vitter, J. S. (1987) An efficient algorithm for sequential
    random sampling.  ACM Trans. Math. Softw. 13(1): 58--67.

This enables the test suite to build with the -property switch enabled.

std.cpuid: vendor()/processor() have not been converted to properties in accordance to core.cpuid.
std.xml: Element.text() cannot be a property due to the optional parameter.

852aa7d723 Remove the DDoc specialization for std.random.uniform. 
Since Bug 6090 has been fixed, there is no need to have a special StdDdoc version
for std.random.uniform which replaces the unmatched ')' with '$(RPAREN)', as shown
in http://d-programming-language.org/phobos/std_random.html#uniform.
