[RFC V1 06/14] vl: precreate phase

[Steve Sistare <steven.sistare@oracle.com>]

Refactor qemu_init into actions performed during the precreate phase,
and actions performed when exiting precreate.  For now, always exit
the precreate phase immediately at init time.  Future patches will add
conditions that cause QEMU to linger in the precreate phase while running
the main loop.
