Enter vmmHEADmaster

A QEMU/KVM virtual machine manager in one POSIX shell script. Each
VM is a directory of plain files under $VMMDIR, configured by a
hand-edited KEY=VALUE file that is parsed rather than sourced, so
nothing in it can inject a raw QEMU argument.

Control is a QMP FIFO pair inside that directory, guarded by its
permissions alone; nothing binds a TCP port. The tests are TAP
without a framework and boot real guests where the host allows.
