Bringing the Power of eBPF to QEMU
summary
Adds an Apache-licensed iovisor/ubpf library into QEMU to run eBPF programs in userspace, with an assembler, disassembler, interpreter and JIT for x86-64 and Arm64. Implements a first module, a userspace eBPF network filter, that matches packet fields, is compiled with clang to eBPF bytecode, loads via QMP/HMP and takes effect no reboot; initial release omits kernel-style verifier, plans RC merge, more helpers and additional hook points.
