07c2399c01 virfdstream: Use messages instead of pipe
One big downside of using the pipe to transfer the data is that
we can really transfer just bare data. No metadata can be carried
through unless some formatted messages are introduced. That would
be quite painful to achieve so let's use a message queue. It's
fairly easy to exchange info between threads now that iohelper is
no longer used.

The reason why we cannot use the FD for plain files directly is
that despite us setting noblock flag on the FD, any
read()/write() blocks regardless (which is a show stopper since
those parts of the code are run from the event loop) and poll()
reports such FD as always readable/writable - even though the
subsequent operation might block.

The pipe is still not gone though. It is used to signal the event
loop that an event occurred (e.g. data is available for reading
in the queue, or vice versa).

ca21d75d25 virsh: add --io when attaching disks to guests
virt-install and virt-manager both default to explicitly setting
"io='native'" in the disk "driver" tag. virsh, however, does not and also
does not provide an option to specify that setting at all.  As a result,
disks use a different IO mechanism (the default, "threads") when attached
post-setup using virsh.  Adding this option allows users to keep disk
performance consistent for disks attached at install, and those attached
afterward.

ed61e0b368 qemu: driver: Allow passing disk target as top image with block commit
Since we allow active layer block commit the users are allowed to commit
the top of the chain (e.g. vda) into the backing image. The API would
not accept that parameter, as it tried to look up the image in the
backing chain.

Add the ability to use the top level image target name explicitly as the
top image of the block commit operation.

ed99660446 qemu: improve detection of UNIX path generated by libvirt
Currently we consider all UNIX paths with specific prefix as generated
by libvirt, but that's a wrong assumption.  Let's make the detection
better by actually checking whether the whole path matches one of the
paths that we generate or generated in the past.

The UNIX path isn't stored in config XML since libvirt-1.3.1.

1a77b97c7f Don't inline virStringTrimOptionalNewline
GCC complains that inlining virStringTrimOptionalNewline is not

  ../../src/util/virfile.c:3987: error: called from here [-Winline]

Inlining this function is not going to be a measurable performance
benefit either, since the time required to execute it is going to
be dominated by running of strlen() over the string, not by the
function call overhead.
