Add two new APIs virNetServerServiceNewPostExecRestart and
virNetServerServicePreExecRestart which allow a virNetServerServicePtr
object to be created from a JSON object and saved to a
JSON object, for the purpose of re-exec'ing a process.
This includes serialization of the listening sockets associated
with the service

In order to support systemd socket based activation, it needs to
be possible to create virNetSocketPtr and virNetServerServicePtr
instance from a pre-opened file descriptor
Currently the virNetServerServicePtr is responsible for
creating the virNetServerClientPtr instance when accepting
a new connection. Change this so that the virNetServerServicePtr
merely gives virNetServerPtr a virNetSocketPtr instance. The
virNetServerPtr can then create the virNetServerClientPtr
as it desires

Per the FSF address could be changed from time to time, and GNU
recommends the following now: (http://www.gnu.org/licenses/gpl-howto.html)
You should have received a copy of the GNU General Public License

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').
Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:
src/security/security_selinux.h
src/security/security_driver.h
src/security/security_selinux.c
src/security/security_apparmor.h
src/security/security_apparmor.c
src/security/security_driver.c
This patch introduces a internal RPC API "virNetServerClose", which
is standalone with "virNetServerFree". it closes all the socket fds,
and unlinks the unix socket paths, regardless of whether the socket
is still referenced or not.
This is to address regression bug:
https://bugzilla.redhat.com/show_bug.cgi?id=725702
The virNetServerClient object had a hardcoded limit of 10 requests
per client. Extend constructor to allow it to be passed in as a
configurable variable. Wire this up to the 'max_client_requests'
config parameter in libvirtd
* daemon/libvirtd.c: Pass max_client_requests into services
* src/rpc/virnetserverservice.c, src/rpc/virnetserverservice.h: Pass
nrequests_client_max to clients
* src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h: Allow
configurable request limit
Allow RPC servers to advertise themselves using MDNS,
via Avahi
* src/rpc/virnetserver.c, src/rpc/virnetserver.h: Allow
registration of MDNS services via avahi
* src/rpc/virnetserverservice.c, src/rpc/virnetserverservice.h: Add
API to fetch the listen port number
* src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Add API to
fetch the local port number
* src/rpc/virnetservermdns.c, src/rpc/virnetservermdns.h: Represent
an MDNS advertisement
To facilitate creation of new daemons providing XDR RPC services,
pull a lot of the libvirtd daemon code into a set of reusable
objects.
* virNetServer: A server contains one or more services which
accept incoming clients. It maintains the list of active
clients. It has a list of RPC programs which can be used
by clients. When clients produce a complete RPC message,
the server passes this onto the corresponding program for
handling, and queues any response back with the client.
* virNetServerClient: Encapsulates a single client connection.
All I/O for the client is handled, reading & writing RPC
messages.
* virNetServerProgram: Handles processing and dispatch of
RPC method calls for a single RPC (program,version).
Multiple programs can be registered with the server.
* virNetServerService: Encapsulates socket(s) listening for
new connections. Each service listens on a single host/port,
but may have multiple sockets if on a dual IPv4/6 host.
Each new daemon now merely has to define the list of RPC procedures
& their handlers. It does not need to deal with any network related
functionality at all.
