If a user hot-attaches the guest agent channel libvirt would ignore it
until the restart of libvirtd or shutdown/destroy and start of the VM
itself.
This patch adds code that opens or closes the guest agent connection
according to the state of the guest agent channel according to
connect/disconnect events.
To allow opening the channel from the event handler qemuConnectAgent
needed to be exported.
When the guest agent channel gets hotplugged to a VM, libvirt would
still report that "QEMU guest agent is not configured" rather than
stating that the connection was not established yet.
Currently the code won't be able to connect to the agent after hotplug
but that will change in a later patch.
As the qemuFindAgentConfig() helper is quite helpful in this case move
it to a more usable place and export it.
Rearrange code so that the local variable is always initialized and
disposed.

Fix for such a case:
1. Domain A and B xml contain the same SRIOV net hostdev(<interface
type='hostdev' /> with same pci address).
2. virsh start A (Successfully, and configure the SRIOV net with
custom mac)
3. virsh start B (Fail because of the hostdev used by domain A or other
reason.)
In step 3, 'virHostdevNetConfigRestore' is called for the hostdev
which is still used by domain A. It makes the mac/vlan of the SRIOV net
change.
Code Change in this fix:
1. As the pci used by other domain have been removed from
'pcidevs' in previous loop, we only restore the nic config for
the hostdev still in 'pcidevs'(used by this domain)
2. update the comments to make it more clear

virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

ListFindByID() still requires to step through items in the hash table
(in the worst case scenario through all of them), lock each one and
compare whether we've found what we're looking for. This is suboptimal
as locking a domain object means we need to wait for the current API
running over the object to finish.
Unfortunately, we can't drop the function completely because we have
this public API virDomainLookupByID which we can't drop.

This hash table will contain the same data as already existing one.
The only difference is that while the first table uses domain uuid as
key, the new table uses domain name. This will allow much faster (and
lockless) lookups by domain name.

When running on FreeBSD, there's a bug in virCommandProcessIO
polling that is triggered by the commandtest.
A test that triggers EPIPE in commandtest (named "test20") hungs
forever on FreeBSD.
Apparently, this happens because FreeBSD sets POLLHUP flag on revents
when stdin in closed. And as the current implementation only checks for
POLLOUT and POLLERR, it ends up looping forever inside
virCommandProcessIO and not trying to do one more write() that would
trigger EPIPE.
To fix that check for the POLLHUP flag along with POLLOUT and POLLERR.
When a user would specify a backing chain index that is above the start
point libvirt would report a rather unhelpful error:
invalid argument: could not find backing store 1 in chain for 'sub/link2'
This patch adds an explicit check that the index is below start point in
the backing store and reports the following error if not:
invalid argument: requested backing store index 1 is above 'sub/../qcow2' in chain for 'sub/link2'
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1177062
Some storage protocols allow to have the @path field in struct
virStorageSource set to NULL. Add NULLSTR() wrappers to handle this
possibility until I finish the storage source error formatter.
