Introduce support for domainInterfaceStats API call for querying
network interface statistics. Consequently it also enables the
use of `virsh domifstat <dom> <interface name>` command plus
seeing the interfaces names instead of "-" when doing
`virsh domiflist <dom>`.

After successful guest creation we fill the network
interfaces names based on domain, device id and append suffix
if it's emulated in the following form: vif<domid>.<devid>[-emu].
We extract the network interfaces info from the libxl_domain_config
object in libxlDomainCreateIfaceNames() to generate ifname. On domain
cleanup we also clear ifname, in case it was set by libvirt (i.e.
being prefixed with "vif"). We also skip these two steps in case the name
of the interface was manually inserted by the adminstrator.

For getting the interface statistics we resort to virNetInterfaceStats
and let libvirt handle the platform specific nits. Note that the latter
is not yet supported in FreeBSD.

virAdmConnect was named after virConnect, but after some discussions,
most of the APIs called will be working with remote daemon and starting
them virAdmDaemon will make more sense.  Only possibly controversal name
is CloseCallback (de)registration, and connecting to the daemon (which
will still be Open/Close), but even this makes sense if one thinks about
the daemon being opened and closed, e.g. as file, etc.

This way all the APIs working with the daemon will start with
virAdmDaemon prefix, they will accept virAdmDaemonPtr as first parameter
and that will better suit with other namings as well (virDomain*,
virAdmServer*, etc.).

Because in virt-admin, the connection name does not refer to a struct
that would have a connect in its name, also adjust 'connname' in
clients.  And because it is not used anywhere in the vsh code, move it
from there into each client.

If VM A is shutdown a by qemu agent at appoximately the same time
an agent EOF of VM A happened, there's a chance that deadlock may occur:

qemuProcessHandleAgentEOF in main thread
A)  priv->agent = NULL; //A happened before B

    //deadlock when we get agent lock which's held by worker thread
    qemuAgentClose(agent);

qemuDomainObjExitAgent called by qemuDomainShutdownFlags in worker thread
B)  hasRefs = virObjectUnref(priv->agent); // priv->agent is NULL,
                                           // return false
    if (hasRefs)
        virObjectUnlock(priv->agent); //agent lock will not be released here

In order to resolve, during EOF close the agent first, then set priv->agent
to NULL to fix the deadlock.

This essentially reverts commit id '1020a504'. It's also of note that commit
id '362d0477' notes a possible/rare deadlock similar to what was seen in
the monitor in commit id '25f582e3'. However, it seems interceding changes
including commit id 'd960d06f' should remove the deadlock issue.

With this change, if EOF is called:

    Get VM lock
    Check if !priv->agent || priv->beingDestroyed, then unlock VM
    Call qemuAgentClose
    Unlock VM

When qemuAgentClose is called
    Get Agent lock
    If Agent->fd open, close it
    Unlock Agent
    Unref Agent

qemuDomainObjEnterAgent
    Enter with VM lock
    Get Agent lock
    Increase Agent refcnt
    Unlock VM

After running agent command, calling qemuDomainObjExitAgent
    Enter with Agent lock
    Unref Agent
    If not last reference, unlock Agent
    Get VM lock

If we were in the middle of an EnterAgent, call Agent command, and
ExitAgent sequence and the EOF code is triggered, then the EOF code
can get the VM lock, make it's checks against !priv->agent ||
priv->beingDestroyed, and call qemuAgentClose. The CloseAgent
would wait to get agent lock. The other thread then will eventually
call ExitAgent, release the Agent lock and unref the Agent. Once
ExitAgent releases the Agent lock, AgentClose will get the Agent
Agent lock, close the fd, unlock the agent, and unref the agent.
The final unref would cause deletion of the agent.

The parameter --disable-dependency-tracking is supposed to speed up
one-time build due to the fact that it disables some dependency
extractors that, apparently, take longer time to execute.  That is a
problem for code that is generated into builddir (especially some
specific subdirectory) because the directory it should be installed to
does not exists in VPATH and without the dependency tracking is not
created.  Generating such file hence fails with -ENOENT.  In order to
keep generating files into builddir instead of srcdir, we must create
the directory ourselves.  This should finally fix the problem that is
being fixed multiple times since its introduction in commit a9fe6203
and let us continue with cleaning those parts of Makefiles that depend
on generating files into the srcdir rather than builddir as it should
be.

Our domain_conf.* files are big enough. Not only they contain XML

harder to maintain. Split virDomainObjList module into a separate

Introduce a new API to get libvirt version. It is worth noting, that
libvirt-admin and libvirt share the same version number. Unfortunately,
our existing API isn't generic enough to be used with virAdmConnectPtr
as well. Also this patch wires up this API to the virt-admin client
as a generic cmdVersion command.

As we need a client disconnect handler, we also need a mechanism to register
such handlers for a client. This patch introduced both the close callbacks and
also the client vshAdmCatchDisconnect handler to be registered with it. By
registering the handler we still need to make sure the client can react to
daemon's events like disconnect or keepalive, so asynchronous I/O event polling
is necessary to be enabled too.

Now that we introduced URI support in libvirt-admin, we should also support URI
aliases during connection establishment phase. After applying this patch,
virAdmConnectOpen will also support VIR_CONNECT_NO_ALIASES flag.

As we need to provide support for URI aliases in libvirt-admin as well, URI
alias matching needs to be internally visible. Since
virConnectOpenResolveURIAlias does have a compatible signature, it could be
easily reused by libvirt-admin. This patch moves URI alias matching to util,
renaming it accordingly.

Since virt-admin should be able to connect to various admin servers
on hosted different daemons, we need to provide URI support to
libvirt-admin.

As we plan to add more and more logic to remote connecting methods,
these cannot be generated from admin_protocol.x anymore. Instead,
this patch implements these to methods explicitly.

By moving the remote version into a separate module, we gain a slightly
better maintainability in the long run than just by leaving it in one
place with the existing libvirt-admin library which can start getting
pretty messy later on.

Since most of our APIs rely on an acive functional connection to a daemon and
we have such a mechanism in libvirt already, there's need to have such a way in
libvirt-admin as well. By introducing a new public API, this patch provides
support to check for an active connection.

This patch introduces virt-admin client which is based on virsh client,
but had to reimplement several methods to meet virt-admin specific needs
or remove unnecessary virsh specific logic.

Unfortunately, client side version retrieval API virGetVersion uses
one-time initialization (due to the fact we might not have initialized the
library by calling connect prior to this) which is not completely compatible
with admin initialization. This API is rather simplistic and reimplementing
it for admin might be the preferred method of reusing it. Note that even though
the method will be reimplemented, the version number is still the same for both
the libvirt and libvirt-admin library.

virConnectGetConfig and virConnectGetConfigPath were static libvirt
methods, merely because there hasn't been any need for having them
internally exported yet. Since libvirt-admin also needs to reference
its config file, 'xGetConfig' should be exported.
Besides moving, this patch also renames the methods accordingly,
as they are libvirt config specific.

Since libvirt-admin is a separate library, it should also have a separate
config file. Available settings are currently the same as for libvirt.conf.

As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.
