math: Replace boost::*::{lcm,gcd}() with portable versions Boost changed the lcm() and gcd() functions in Boost 1.67. This creates portable UHD versions to be used instead. They use various Boost versions under the hood conditionally.

uhd: math: Add a sign() function We've been having issues with moving locations of Boost headers for this function, and it's simple enough to implement ourselves.

}
uhd: math: Replace wrap-frequency math with a single function In multiple places in the UHD code, we were doing the same calculation for a wrapped frequency (wrap it into the first Nyquist zone). This math was using boost::math, too. Instead of editing every instance, we create a new function, uhd::math::wrap_frequency(), and replace all of its separate implementations with this function. The new function also no longer relies on boost::math::sign.
