[libvirt] [PATCHv4 3/5] smartcard: check for qemu capability

[Eric Blake]

Qemu smartcard support exists on branches (such as
http://cgit.freedesktop.org/~alon/qemu/commit/?h=usb_ccid.v15&id=024a37b)
but is not yet upstream.  Once an upstream version exists, then we
can add new -help and -device ? output files  to tests/qemuhelptest
to prove that the new flag works.

* src/qemu/qemu_capabilities.h (QEMUD_CMD_FLAG_USB_CCID): New
flag.
* src/qemu/qemu_capabilities.c (qemuCapsExtractDeviceStr)
(qemuCapsParseDeviceStr): Check for smartcard device support.
