debuginfod: get debugging data + sources easily
summary
A lightweight HTTP server indexes RPMs and build trees and serves DWARF debuginfo and source files keyed by build-id lookup, reachable with a single DEBUGINFOD_URLS env var. Clients (gdb, systemtap, perf and more; valgrind support in progress) query the server and automatically fetch missing .debug and source files; demos show systemtap producing call graphs and gdb/valgrind resolving symbols and line numbers. Servers run unprivileged, support federation, expose Prometheus metrics, and are already available on public and distro mirrors.
