I picked up a SDRplay RSP2 recently, and the gr-osmosdr support needed 
some work. Here's a rewrite that works with RSP2 and has other 
improvements. When the RSP1A comes in, I'll finish support for that. No 
plans to pick up a RSP1, but someone can see if this works if 
interested. This was tested against the Nov 2017 binary blob.


Complete rewrite of sdrplay support

- Supports RSP2
- Will support RSP1A when hardware arrives
- RSP1 is untested
- Uses streaming callbacks instead of polling
- Tuning, gain control imporoved, AGC supported
- Better performance (one less layer of buffers)
