6bb4986b0b Implement virDomainUpdateDeviceFlags API in all drivers with media change
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

2e56fb2bcc build: consistently use C99 varargs macros

with the C99 vararg macro syntax.

cabc2cc98f Implmentation of new APIs to checking state/persistence of objects
This implements the virConnectIsSecure, virConnectIsEncrypted,
virDomainIsPersistent, virDomainIsActive, virNetworkIsActive,
virNetworkIsPersistent, virStoragePoolIsActive,
virStoragePoolIsPersistent, virInterfaceIsActive APIs in
(nearly) all drivers. Exceptions are:

 phyp: missing domainIsActive/Persistent
 esx: missing domainIsPersistent
 opennebula: missing domainIsActive/Persistent

74c81b5d93 Fix problems in the Xen inotify driver.
In xenInotifyXendDomainsDirLookup() the wrong UUID variable is used
to search in the config info list.

In xenInotifyEvent() the event is dispatched if it's NULL.

Both were introduced in bc898df2c7.

6ed7374c5a Fix xen driver refcounting.
The commit cb51aa48a7 "Fix up connection
reference counting." changed the driver closing and virConnectPtr
unref-logic in virConnectClose().

Before this commit virConnectClose() closed all drivers of the given
virConnectPtr and virUnrefConnect()'ed it afterwards. After this
commit the driver-closing is done in virUnrefConnect() if and only if
the ref-count of the virConnectPtr dropped to zero.

This change in execution order leads to a virConnectPtr leak, at least
for connections to Xen.

The relevant call sequences:

virConnectOpen() -> xenUnifiedOpen() ...

... xenInotifyOpen() -> virConnectRef(conn)

... xenStoreOpen() -> xenStoreAddWatch() -> conn->refs++

virConnectClose() -> xenUnifiedClose() ...

... xenInotifyClose() -> virUnrefConnect(conn)

... xenStoreClose() -> xenStoreRemoveWatch() -> virUnrefConnect(conn)

Before the commit this additional virConnectRef/virUnrefConnect calls
where no problem, because virConnectClose() closed the drivers
explicitly and the additional refs added by the Xen subdrivers were
removed properly. After the commit this additional refs result in a
virConnectPtr leak (including a leak of the hypercall file handle;
that's how I noticed this problem), because now the drivers are only
close if and only if the ref-count drops to zero, but this cannot
happen anymore, because the additional refs from the Xen subdrivers
would only be removed if the drivers get closed, but that doesn't
happen because the ref-count cannot drop to zero.

The fix for this problem is simple: remove the
virConnectRef/virUnrefConnect calls from the Xen subdrivers (see
attached patch). Maybe someone could explain why the Xen Inotify and
Xen Store driver do this extra ref-counting, but none of the other Xen
subdrivers. It seems unnecessary to me and can be removed without
problems.
