rtl_hpsdr an RTL to HPSDR software translation server

I am releasing to the public via GPL an RTL to HPSDR software translation server. Hosted on https://github.com/n1gp/rtl_hpsdr Screenshots listed and end. README: It currently builds and runs on Linux. It identifies and uses up to seven (theoretically eight) USB RTL2832U-based DVB-T dongles. The dongles can be set up with an up converter or use RTL direct-mode for HF receive. Or direct input to provide it's native > HF receive range. The program can be passed in a variety of command line options. One of which is a frequency offset not only for up converter use but also to allow a full range of frequency options to HPSDR programs that are coded to only allow the real HPSDR radio's (i.e. Hermes) frequency range which is from 10KHz to 55MHz. The main purpose of this program is to provide a mechanism that allows RTL Dongle owners the ability to use them on HPSDR specific software programs. One such program, cuSDR64 has the ability to control and display up to 7 rcvr slices simultaneously. With rtl_hpsdr, if your host has the horsepower, you can run 7 RTL Dongles to emulate the HPSDR rcvr. cuSDR64 also can be built and run on Linux. Since the real HPSDR (i.e. Hermes) rcvr can do up to eight rcvr slices, there is a concept of 'COPY' rcvrs in this server. This would allow one to use HPSDR programs that expected more rcvrs than were attached. Currently if a program request more rcvrs than are actually attached the rtl_hpsdr server will make copies of the last 'real' rcvr. This alows one to only have one RTL dongle attached and run PowerSDR mRX which may expect up to four rcvr slices. Refer to: http://openhpsdr.org/softwareinfo.php for a list of HPSDR supported applications. I have tested this only on cuSDR64, cuSDR32, and PowerSDR mRX. I was successful running 7 RTL dongles simultaneously on a Quad core ARM Cortex A9 based mini-pc, model EKB311 running a version of Picuntu, http://ubuntu.g8.net/ This was using R820T based dongles on a USB 2.0 hub. I did have to replace the USB hub power supply with one that provided 5V @ 2A.
