quorum: Add quorum mechanism.

This patchset enables the core of the quorum mechanism.
The num_children reads are compared to get the majority version and if this
version exists more than threshold times the guest won't see the error at all.

If a block is corrupted or if an error occurs during an IO or if the quorum...

quorum: Add quorum_getlength().

Check that every bs file returns the same length.
Otherwise, return -EIO to disable the quorum and
avoid length discrepancy.

blkverify: Extract qemu_iovec_clone() and qemu_iovec_compare() from blkverify.

qemu_iovec_compare() will be used to compare IOs vectors in quorum blkverify
mode. The patch extracts these functions in order to factorize the code.

quorum: Create quorum.c, add QuorumChildRequest and QuorumAIOCB.

Quorum is a block filter mirroring writes to num_children children.
For reads quorum reads each children and does a vote.
