Since we have drivers which depend on each other (ie QEMU/LXC
depend on the network driver APIs), we need to use RTLD_GLOBAL
instead of RTLD_LOCAL. While this pollutes the calling binary
with many more symbols, this is no worse than if we directly
link to the drivers, and this only applies to libvirtd

There were two API in driver.c that were silently masking flags
bits prior to calling out to the drivers, and several others
that were explicitly masking flags bits.  This is not
forward-compatible - if we ever have that many flags in the
future, then talking to an old server that masks out the
flags would be indistinguishable from talking to a new server
that can honor the flag.  In general, libvirt.c should forward
_all_ flags on to drivers, and only the drivers should reject
unknown flags.

In the case of virDrvSecretGetValue, the solution is to separate
the internal driver callback function to have two parameters
instead of one, with only one parameter affected by the public
API.  In the case of virDomainGetXMLDesc, it turns out that
no one was ever mixing VIR_DOMAIN_XML_INTERNAL_STATUS with
the dumpxml path in the first place; that internal flag was
only used in saving and restoring state files, which happened
to be in functions internal to a single file, so there is no
mixing of the internal flag with a public flags argument.
Additionally, virDomainMemoryStats passed a flags argument
over RPC, but not to the driver.

Jim Meyering recently improved gnulib to catch various grammar

Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'

followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.

* src/util/logging.h (DEBUG, DEBUG0): Delete.

* global: Change remaining clients over to VIR_DEBUG counterpart.

When built as modules, the connection drivers live

Run this:
  git grep -l 'VIR_ERROR\s*("'|xargs perl -pi -e \
    's/(VIR_ERROR)\s*\((".*?"),/$1(_($2),/'

This wires up the remote driver to handle the new events APIs.
The public API allows an application to request a callback filters
events to a specific domain object, and register multiple callbacks
for the same event type. On the wire there are two strategies for
this

 - Register multiple callbacks with the remote daemon, each
   with filtering as needed
 - Register only one callback per event type, with no filtering

Both approaches have potential inefficiency. In the first scheme,
the same event gets sent over the wire many times if multiple
callbacks are registered. With the second scheme, unneccessary
events get sent over the wire if a per-domain filter is set on
the client. The second scheme is far easier to implement though,
so this patch takes that approach.

* daemon/dispatch.h: Don't export remoteRelayDomainEvent since it
  is no longer needed for unregistering callbacks, instead the
  unique callback ID is used
* daemon/libvirtd.c, daemon/libvirtd.h: Track and unregister
  callbacks based on callback ID, instead of function pointer
* daemon/remote.c: Switch over to using virConnectDomainEventRegisterAny
  instead of legacy virConnectDomainEventRegister function. Refactor
  remoteDispatchDomainEventSend() to cope with arbitrary event types
* src/driver.h, src/driver.c: Move verify() call into source file
  instead of header, to avoid polluting the global namespace with
  the verify function name
* src/remote/remote_driver.c: Implement new APIs for event
  registration. Refactor processCallDispatchMessage() to cope
  with arbitrary incoming event types. Merge remoteDomainQueueEvent()
  into processCallDispatchMessage() to avoid duplication of code.
  Rename remoteDomainReadEvent() to remoteDomainReadEventLifecycle()
* src/remote/remote_protocol.x: Define wire format for the new
  virConnectDomainEventRegisterAny and virConnectDomainEventDeregisterAny
  functions

* global: patch created by running:
for f in $(git ls-files '*.[ch]') ; do
    cppi $f > $f.t && mv $f.t $f
done

The 'asprintf' -> 'virAsprintf' transition made in
[043d702f] "use virAsprintf instead of asprintf" introducted
a build error for 'driver.c' as 'util.h' has to be included.
