vl: move all generic initialization out of vl.c
qdev_machine_creation_done is only setting a flag now. Extend it to move more code out of vl.c. Leave only consistency checks and gdbserver processing in qemu_machine_creation_done. gdbserver_start can be moved after qdev_machine_creation_done because it only does listen on the socket and creates some internal data structures; it does not send any data (e.g. guest state) over the socket.
