Since it's introduction in v0.9.7-147-gf4324e3292 the
virNetServerClientInitKeepAlive() function returned nothing than
a negative one. Fortunately, this did not pose any problem
because we ignored the retval happily. Well, it's time to check
for the retval because the function might fail regularly.

The node device APIs are a little unusual because we don't use a
"remote_nonnull_node_device" object on the wire, instead we just
have a "remote_string" for the device name. This meant dispatcher
code generation needed special cases. In doing so we mistakenly
used the virNodeDeviceLookupByName() API which gets dispatched
into the driver, instead of get_nonnull_node_device() which
directly populates a virNodeDevicePtr object.
This wasn't a problem with monolithic libvirtd, as the
virNodeDeviceLookupByName() API call was trivially satisfied
by the registered driver, albeit with an extra (undesirable)
authentication check. With the split daemons, the call to
virNodeDeviceLookupByName() fails in virtqemud, because the
node device driver obviously doesn't exist in that daemon.

Despite their names, the following APIs:
virNodeDeviceDettach
virNodeDeviceDetachFlags
virNodeDeviceReAttach
virNodeDeviceReset
are all handled by the virt drivers, not the node device driver.
A bug in the RPC generator meant that these APIs were sent to
the nodedev driver for handling. This caused breakage with the
split daemons, since nothing was available to process them.

This deletes all trace of gnulib from libvirt. We still

solution taken was to update it when running autogen.sh.
Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
