uhd: fixing MSVC warnings

Small changes to remove various compiler warnings found in MSVC
- Adding uhd::narrow_cast to verious spots
- wavetable.hpp: all floats literals in the wavetable.
- paths_test: unnecessary character escape
- replay example: remove unreferenced noc_id
- adfXXXX: Fixing qualifiers to match between parent and derived
  classes
- rpc, block_id: Removing unused name in try...catch
