Enable retrieval of the number of maximum clients connected to all sockets
combined, as well as the number of maximum clients waiting for authentication,
in order to be successfully connected. These are the attributes configurable
through libvirtd.conf, however, it could be handy to not only know values for
these limits, but also the values for the current number of clients
connected and number of clients currently waiting for authentication which are
changing dynamically. This API does both, retrieves the limits as well as the
current dynamic values.

Once we're able to list and identify all clients connected to a specific
server, we can then support force-closing a connection. This patch introduces
a simple API calling virNetServerClientClose on a specific client, which
can be later extended easily, e.g. by sending an event once the client is
disconnected successfully.

Expose a public API to retrieve some identity and connection information about
a client connected to the specified server on daemon. The identity info
retrieved is mostly connection transport dependent, i.e. there won't be any
socket address returned for a local (UNIX socket) connection, while on the
other hand, when connected through TLS or unencrypted TCP, obviously no UNIX
process identification will be present in the returned data. All supported
values that can be returned in typed params are exposed and documented in
include/libvirt/libvirt-admin.h

Just like with server-related APIs, before any of client-based APIs can be
called, a reference to a client-side client object needs to be obtained. For
this purpose, a lookup method should exist. Apart from the client retrieval
logic, a new error code for non-existent client had to be added as well.

Finally add public method to retrieve the list of currently connected clients
to a given server.

Since threadpool increments the current number of threads according to current
load, i.e. how many jobs are waiting in the queue. The count however, is
constrained by max and min limits of workers. The logic of this new API works
like this:
    1) setting the minimum
        a) When the limit is increased, depending on the current number of
           threads, new threads are possibly spawned if the current number of
           threads is less than the new minimum limit
        b) Decreasing the minimum limit has no possible effect on the current
           number of threads
    2) setting the maximum
        a) Icreasing the maximum limit has no immediate effect on the current
           number of threads, it only allows the threadpool to spawn more
           threads when new jobs, that would otherwise end up queued, arrive.
        b) Decreasing the maximum limit may affect the current number of
           threads, if the current number of threads is less than the new
           maximum limit. Since there may be some ongoing time-consuming jobs
           that would effectively block this API from killing any threads.
           Therefore, this API is asynchronous with best-effort execution,
           i.e. the necessary number of workers will be terminated once they
           finish their previous job, unless other workers had already
           terminated, decreasing the limit to the requested value.
    3) setting priority workers
        - both increase and decrease in count of these workers have an
          immediate impact on the current number of workers, new ones will be
          spawned or some of them get terminated respectively.

New API to retrieve current server workerpool specs. Since it uses typed
parameters, more specs to retrieve can be further included in the pool of
supported ones.

It does not have a suffix ByName because there are no other means of
looking up the server and since the name is known, this should be the
preferred one.

virAdm is prefix only used on the client side.  Or at least for now.  On
server, though, this corresponds to virNet structures (virAdmConnect is
virNetDaemon, virAdmServer should be virNetServer, in the future
virAdmClient will be resolved to virNetServerClient, and so on).

This will also make future work clearer and easier.

This API is merely a convenience API, i.e. when managing clients connected to
daemon's servers, we should know (convenience) which server the specific client
is connected to. This implies a client-side representation of a server along
with a basic API to let the administrating client know what servers are actually
available on the daemon.

We currently blindly accept any numeric value as a GIC version, even
though only GIC v2 and GIC v3 actually exist; on the other hand, we
reject "host", which is a perfectly legitimate value for QEMU guests.

This new enumeration contains all GIC versions libvirt is aware of.

Which is already included by "internal.h", later patch will add
syntax-check to avoid it.
