caaa1b8f13 Define an API for registering incoming message dispatch filters
All incoming messages currently get routed to the generic method
remoteDispatchClientRequest() for processing. To allow incoming
data stream messages to bypass this and be routed to a specific
location, a concept of dispatch filters is introduced.

* qemud/qemud.h: Add a qemud_client_filter struct and a callback
  qemud_client_filter_func. Maintain a list of filters on every
  struct qemud_client
* qemud/qemud.c: Move remoteDecodeClientMessageHeader() out of
  qemudWorker() into qemudDispatchClientRead(). Check registered
  message filters in qemudDispatchClientRead() to decide where
  to send incoming messages for dispatch.

af4dad0fa2 Change the way client event loop watches are managed
The current qemudRegisterClientEvent() code is used both for
registering the initial socket watch, and updating the already
registered watch. This causes unneccessary complexity in alot
of code which only cares about updating existing watches. The
updating of a watch cannot ever fail, nor is a reference to the
'qemud_server' object required.

This introduces a new qemudUpdateClientEvent() method for that
case, allowing the elimination of unneccessary error checking
and removal of the server back-reference in struct qemud_client.

* qemud/qemud.h: Remove 'server' field from struct qemud_client.
  Add qemudUpdateClientEvent() method. Remove 'update' param
  from qemudRegisterClientEvent method
* qemud/dispatch.c, qemud/qemud.c, qemud/remote.c: Update alot
  of code to use qemudUpdateClientEvent() instead of
  qemudRegisterClientEvent(). Move more logic from remoteRelayDomainEvent
  into remoteDispatchDomainEventSend.

c40e14b4be Move queuing of RPC replies into dispatch code
This removes an assumption from qemudWorker() code that every
incoming message will generate a reply.

* qemud/dispatch.c: remoteDispatchClientRequest now has responsibility
  for queuing the reply message to the RPC call
* qemud/qemud.c: Do not queue the RPC call reply in qemudWorker(),
  allowing remoteDispatchClientRequest() to take care of it

081c6330b1 Decode incoming request header before invoking dispatch code
Separate the decoding of incoming request header out from the
dispatch code. This will allow later code to making dispatcher
routing decisions based on the header field data.

* qemud/dispatch.c, qemud/dispatch.h: Add remoteDecodeClientMessageHeader
  API for decoding the header of a client message. Update the
  remoteDispatchClientRequest method to assume a pre-decoded
  header.
* qemud/qemud.h: Include a 'remote_message_header' field in
  'struct qemud_client_message' for pre-decoded header data
* qemud/qemud.c: Decode the incoming client message header before
  invoking remoteDispatchClientRequest

98352a103b libvirtd: new config-file option: unix_sock_dir
Before this change, the unix socket directory was hard-coded
to be e.g., /var/run/libvirt for euid==0 and ~/.libvirt otherwise.
With this change, you may now specify that directory in libvirtd's
config file via a line like this: unix_sock_dir = "/var/run/libvirt".
This is essential for running tests that do not impinge on any
existing libvirtd process, and in running tests in parallel.
* qemud/libvirtd.conf (unix_sock_dir): Add comment and example.
* qemud/qemud.h (struct qemud_server) [logDir]: Change type
from char[PATH_MAX] to char*.
* qemud/qemud.c (unix_sock_dir): New global
(remoteReadConfigFile): Set the global.
(qemudInitPaths): Use the global, unix_sock_dir, if non-NULL.
One minor improvement: unlink both sockets or none, never
just one of them.
(qemudCleanup): Free logDir.
(main): Use the new global rather than hard-coding "/run/libvirt".
* qemud/libvirtd.aug (sock_acl_entry): Add "unix_sock_dir".
