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.

win32: add readv/writev emulation

Commit e9d8fbf (qemu-file: do not use stdio for qemu_fdopen, 2013-03-27)
introduced a usage of writev, which mingw32 does not have. Even though
qemu_fdopen itself is not used on mingw32, the future-proof solution is
to add an implementation of it. This is simple and similar to how we...

iov: handle partial writes from sendmsg and recvmsg

Partial writes can still happen in sendmsg and recvmsg, if a
signal is received in the middle of a write. To handle this,
retry the operation with a new offset/bytes pair.

iov: reorganize iov_send_recv, part 1

Once the initial part of the iov is dropped, it is not used anymore.
Modify iov/iovcnt directly instead of adjusting them with the "si"
variable.

iov: reorganize iov_send_recv, part 2

Do not touch the "bytes" argument anymore. Instead, remember the
original length of the last iovec if we touch it, and restore it
afterwards.

This requires undoing the changes in opposite order. The previous
algorithm didn't care....

qemu/iovec: Don't assert if sbytes is zero

Since these values can possibly be sent from guest (for hw/9pfs), do a sanity check
on them. A 9p write request with 0 bytes caused qemu to abort without this patch
