spice: add chardev (v5)

Adding a chardev backend for spice, where spice determines what
to do with it based on the name attribute given during chardev creation.
For usage by spice vdagent in conjunction with a properly named
virtio-serial device, and future smartcard channel usage.

Example usage:
 qemu -device virtio-serial -chardev spicevmc,name=vdagent,id=vdagent \
 -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

v4->v5:
 * add tracing events
 * fix missing comma
 * fix help string to show debug is optional

v3->v4:
 * updated commit message

v1->v3 changes: (v2 had a wrong commit message)
 * removed spice-qemu-char.h, folded into ui/qemu-spice.h
 * removed dead IOCTL code
 * removed comment
 * removed ifdef CONFIG_SPICE from qemu-config.c and qemu-options.hx help.
