This is a follow up patch of commit f9ce7dad, it modifies all
the files which declare the copyright like "See COPYING.LIB for
the License of this software" to use the detailed/consistent one.

And deserts the outdated comments like:

 * libvirt-qemu.h:
 * Summary: qemu specific interfaces
 * Description: Provides the interfaces of the libvirt library to handle
 *              qemu specific methods
 *
 * Copy:  Copyright (C) 2010, 2012 Red Hat, Inc.

Uses the more compact style like:

 * libvirt-qemu.h: Interfaces specific for QEMU/KVM driver
 *
 * Copyright (C) 2010, 2012 Red Hat, Inc.

In preparation for the patch to include Murmurhash3, which
introduces a virhashcode.h and virhashcode.c files, rename
the existing hash.h and hash.c to virhash.h and virhash.c
respectively.

The Xen & VBox drivers deal with callbacks & dispatching of
events directly. All the other drivers use a timer to dispatch
events from a clean stack state, rather than deep inside the
drivers. Convert Xen & VBox over to virDomainEventState so
that they match behaviour of other drivers

* src/conf/domain_event.c: Return count of remaining
  callbacks when unregistering event callback
* src/vbox/vbox_tmpl.c, src/xen/xen_driver.c,
  src/xen/xen_driver.h: Convert to virDomainEventState

do
  git grep "\(\.\|->\)$f\b" src/xen
done | cat

and looking through the resulting list to see which callback struct
members are still necessary.

* src/xen/xen_driver.h (xenUnifiedDriver): Drop all callbacks that
are only used directly.

No need to use a for loop if we know there is exactly one client.

Using C99 initializers and xen-specific prefixes will make it
so that future patches are less likely to add callback members
to the xenUnifiedDriver struct, since the goal is to get rid
of the callback struct in the first place.

members, to make it obvious which ones are still in use.

Build failure on xenapi_driver from compiler warnings (flags was unused).

Build failure on xen (incorrect number of arguments).  And in fixing
that, I obeyed the comments of struct xenUnifiedDriver that state
that we want to minimize the number of callback functions in that
struct, not add to it.

arguments.

Also fix a logic bug in xenXMDomain{Attach,Detach}DeviceFlags,

params and nparams are essential and cannot be NULL. Check this in
libvirt.c and remove redundant checks from the drivers (e.g. xend).

Instead of enforcing that nparams must point to exact same value as
returned by virDomainGetSchedulerType relax this to a lower bound
check. This is what some drivers (e.g. xen hypervisor and esx)
already did. Other drivers (e.g. xend) didn't check nparams at all
and assumed that there is enough space in params.

Unify the behavior in all drivers to a lower bound check and update
nparams to the number of valid values in params on success.

Suggested by danpb, as it's not up-to-date anymore and
lacks many functions that were added to libvirtd.

* src/xen/xen_driver.h (includes): Include main xen headers
here...

the sub-drivers.

* src/xen/xen_hypervisor.c (MAX_VIRT_CPUS): Move...

same value.

where long is 64-bits.

Tested with RHEL 5.6 (xendConfigVersion 2, where xend_internal
controls live domains and xm_internal controls inactive domains).
Hopefully this works with xendConfigVersion 3 (where xend_internal
controls everything).

To allow the new virDomainUpdateDeviceFlags() API to be universally
used with all drivers, this patch adds an impl to all the current
drivers which support CDROM or Floppy disk media change via the
current virDomainAttachDeviceFlags API

This implements the virConnectIsSecure, virConnectIsEncrypted,
virDomainIsPersistent, virDomainIsActive, virNetworkIsActive,
virNetworkIsPersistent, virStoragePoolIsActive,

 opennebula: missing domainIsActive/Persistent
