* DESCRIPTION
* Converts string of characters representing list of numbers into array of
* numbers. Allowed formats are:
* 0,1,2,3
* 0-10,20-18
* 1,3,5-8,10,0x10-12
*
* Numbers can be in decimal or hexadecimal format.
*
* PARAMETERS
* `s' String representing list of unsigned numbers.
* `nums' Array to put converted numeric values into.
* `nums_len' Maximum number of elements that nums can accommodate.
*
* RETURN VALUE
* Number of elements placed into nums.
