uhd: created a meta range that is a range of ranges for gains and freqs

created a templated range that that holds a start, stop, and step

created a meta-range template that is a vector of ranges
meta-range can calculate the overall start, stop, step
or be indexed to get at components

replaced instances of range.min, max, step with the functions
start() stop() and step()

the xcvr frequency range is now expressed in as two ranges
(have to fix its clip function though)
