/* Structured random number generator.
* Instead of the caller converting bits from Random() to a meaningful
* value, the caller provides metadata that is used to return the
* meaningful value directly. This allows code to interpret the random
* call, for example, battle tests know what the domain of a random call
* is, and can exhaustively test it.
*
* RandomTag identifies the purpose of the value.
*
* RandomUniform(tag, lo, hi) returns a number from lo to hi inclusive.
*
* RandomPercentage(tag, t) returns FALSE with probability (1-t)/100,
* and TRUE with probability t/100.
*
* RandomWeighted(tag, w0, w1, ... wN) returns a number from 0 to N
* inclusive. The return value is proportional to the weights, e.g.
* RandomWeighted(..., 1, 1) returns 50% 0s and 50% 1s.
* RandomWeighted(..., 2, 1) returns 2/3 0s and 1/3 1s. */
