Fix mDNS discovery ambiguity where multiple devices across
different network segments/subnets can advertise the same hostname (e.g.
"ip:pluto.local"), resulting in non-unique or misleading URIs.
Replace unresolved mDNS hostnames with the actual discovered endpoint
reported in the scan description.
- Detect ".local" URIs on IP backend and substitute hostname with
resolved endpoint from libiio scan results.
- Preserve URI semantics:
- Keep backend prefix ("ip:")
- Preserve optional port suffix
- Correctly format IPv6 literals with RFC2732 bracket notation when
required
- Add replaceHostnameWithIP() to perform URI normalization during scan:
- Only applies to IP backend URIs
- Only triggers for mDNS-based ".local" hostnames
- Uses scan-provided endpoint (from description string) as authoritative
address instead of advertised hostname
- Extend scan() to emit both original and resolved URIs for debugging
and verification during device discovery.
This resolves inconsistent device addressing when multiple PlutoSDRs
are accessible via mDNS across different subnets or network segments.
No change to backend enumeration or device identity logic; this only
normalizes .local IP URI resolution at scan time.

Ancillary projects
- SDRangelcli is a web application that can be used to control a headless (server flavor) instance of SDRangel. It can also be used as a remote control for the GUI flavor.
- SDRangel-Docker is a collection of Docker files and scripts to facilitate building and running SDRangel in a Docker container. Works for either the GUI (only on a Linux host) or the server.
