Conversion error when compiling about soapyuhd

[guruofquality]

I think some typedefs changed in newer UHD APIs. Does this patch help?

If I add the boost/foreach.hpp include, and the auto in a couple spots, I still get a few errors like this:

UHDSoapyDevice.cpp:859:71: error: no match for ‘operator=’ (operand types are ‘std::map<long unsigned int, boost::weak_ptruhd::tx_streamer >::mapped_type {aka boost::weak_ptruhd::tx_streamer}’ and ‘uhd::tx_streamer::sptr {aka std::shared_ptruhd::tx_streamer}’)
BOOST_FOREACH(const size_t ch, args.channels) _tx_streamers[ch] = stream;

If you can fire up an Ubuntu 18 VM you should see it pretty quick.
