virt plugin: fail init with no libvirt connection

Even though we handle disconnection and reconnection
in the read() callback, we expect the libvirt connection
to be available most of the time, including the init()
stage.

Thus, let's fail init() if the connection is not available.

One reader instance will only query the domains with attached

The special-purpose reader instance #0, guaranteed to be always present,

virt plugin: Support for multiple read callbacks

Add support to register more than one read callbacks in the
reader thread pool.
The default configuration is to use just one read callback,
for backward compatibility. No user-visible changes are expected
in this scenario.

virt plugin: Factor the read state into a struct

The lv_read function needs some bookkeeping data to track which
domain, block interface and network interface should be polled
for new data.

This patch factors out this data, previously scattered as module
globals, in a new struct. This makes the code a little tidier
and more reusable.
