I don't think upstream qemu has (or will/should have) any blktap
support.

Having said that it's not exactly clear what, if anything, this blktap
support in qemu-xen is actually used for... It looks a bit like once
upon time it was an option to use qemu to provide the blktap (v1)
userspace backend instead of the tapdisk process (look for qemu and
use_ioemu in tools/blktap/drivers/blktapctrl.c). This functionality does
not appear to be present in blktap2.
