Extend libibmocksys.so with umad ioctl/read/write/poll so ibping works without ib_umad hardware. Same-LID pings loop in-process; cross-HCA traffic uses a global umad-bus keyed by MAD TID. Adds e2e validation, Linux integration test, and CI mockib-integration job. Signed-off-by: Giulio Calzolari <gcalzolari@nvidia.com>
