We already have a public virDomainPinVcpu, which implies that
Pin and Vcpu are treated as separate words.  Unreleased commit
e261987c introduced virDomainGetVcpupinInfo as the first public
API that used Vcpupin, although we had prior internal uses of
that spelling.  For consistency, change the spelling to be two
words everywhere, regardless of whether pin comes first or last.

This patch introduces a new libvirt API (virDomainGetVcpupinInfo),
as a counterpart to virDomainPinVcpuFlags.

We can use virDomainGetVcpus API to retrieve CPU affinity information,
but can't use this API against inactive domains (at least in case of KVM),
as it lacks a flags parameter.
The usual thing is to add a new virDomainGetVcpusFlags, but that API name
is already occupied by the counterpart to virDomainGetMaxVcpus, which
has a completely different signature.

The virDomainGetVcpupinInfo is the new API to retrieve CPU affinity
information of active and inactive domains.  While the usual convention
is to list an array before its length, this API violates that rule
in order to be more like virDomainGetVcpus (where maxinfo was doing
double-duty as the length of two different arrays).

Since we virEventRegisterDefaultImpl is now a public API, callers need
a way to invoke the default registered Handle and Timeout functions. We
already have general functions for these internally, so promote
them to the public API.

v2:
    Actually add APIs to libvirt.h

The API can be used to query current state of an interface to VMM used
to control a domain. In QEMU world this translates into monitor
connection.

Set up the types for the block pull functions and insert them into the
virDriver structure definition.  Symbols are exported in this patch to prevent
documentation compile failures.

This patch introduces a new libvirt API virDomainPinVcpuFlags,
a direct extension from the existing virDomainPinVcpu

If we can choose live or config when setting, then we need to
be able to choose which one we are querying.

Also, make the documentation clear that set must use a non-empty
subset (some of the hypervisors fail if params is NULL).

* include/libvirt/libvirt.h.in
(virDomainGetSchedulerParametersFlags): New prototype.
* src/libvirt.c (virDomainGetSchedulerParametersFlags): Implement
it.
* src/libvirt_public.syms: Export it.
* python/generator.py (skip_impl): Don't auto-generate.
* src/driver.h (virDrvDomainGetSchedulerParametersFlags): New
callback.

This is the API agreed on in:

  https://www.redhat.com/archives/libvir-list/2011-May/msg00026.html

(with a slight name change to use "...begin" rather than
"...start"). This implements transactional changes to the host network
config. When a transaction is begun with ncf_change_begin(), all other
netcf APIs will continue to work as they always have, but a snapshot
of the existing config will be taken, allowing reversion (rollback,
using ncf_change_rollback()) to the exact state of config at the time
ncf_change_begin() was called. Alternately, if it's determined that
the new changes are acceptable, ncf_change_commit() can be called,
which will eliminate the snapshot and make the changes permanent.

As a failsafe measure, if neither ncf_change_commit() or
ncf_change_rollback() is called by the next time the system reboots,
the netcf-transaction initscript will be automatically called to
rollback the changes.

There are two pieces of information which are desirable for
migration, which cannot be supplied by applications

 - The explicit QEMU migration URI, while using Peer2Peer
   migration
 - An override for the target VM XML

This introduces two new public APIs to support these extra
parameters. There is no need for extra wire protocool changes,
since this is supported by the v3 migration enhancements

* include/libvirt/libvirt.h.in,
  src/libvirt.c, src/libvirt_public.syms: Add virDomainMigrate2
  and virDomainMigrateToURI2

This new function allows aditional flags to be passed into from
the virsh command line.

This API is supposed to replace virDomainGetInfo when the only purpose
of calling it is getting current domain status.

Add public API for taking screenshots of current domain console.

* include/libvirt/libvirt.h.in: add virDomainScreenshot
* src/libvirt_public.syms: Export new symbol

New APIs are added allowing streaming of content to/from
storage volumes.

  virStorageVolDownload APIs

It is possible to set a migration speed limit when starting
migration. This new API allows the speed limit to be changed
on the fly to adjust to changing conditions

Not all applications have an existing event loop they need
to integrate with. Forcing them to implement the libvirt
event loop integration APIs is an undue burden. This just
exposes our simple poll() based implementation for apps
to use. So instead of calling

   virEventRegister(....callbacks...)

The app would call

   virEventRegisterDefaultImpl()

And then have a thread somewhere calling

    static bool quit = false;
    ....
    while (!quit)

The new virConnectGetSysinfo() API allows one to get the system

<os><smbios mode='sysinfo'/></os>.

To enable virsh console (or equivalent) to be used remotely
it is necessary to provide remote access to the /dev/pts/XXX
pseudo-TTY associated with the console/serial/parallel device
in the guest. The virStream API provide a bi-directional I/O
stream capability that can be used for this purpose. This
patch thus introduces a virDomainOpenConsole API that uses
the stream APIs.

virDomainManagedSave() is to be run on a running domain. Once the call
complete, as in virDomainSave() the domain is stopped upon completion,
but there is no restore counterpart as any order to start the domain
from the API would load the state from the managed file, similary if
the domain is autostarted when libvirtd starts.
Once a domain has restarted his managed save image is destroyed,
basically managed save image can only exist for a stopped domain,
for a running domain that would be by definition outdated data.

The current API for domain events has a number of problems

 - Only allows for domain lifecycle change events
 - Does not allow the same callback to be registered multiple times
 - Does not allow filtering of events to a specific domain

This introduces a new more general purpose domain events API

  typedef enum {
     VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0,       /* virConnectDomainEventCallback */
      ...more events later..
  }

  int virConnectDomainEventRegisterAny(virConnectPtr conn,
                                       virDomainPtr dom, /* Optional, to filter */
                                       int eventID,
                                       virConnectDomainEventGenericCallback cb,
                                       void *opaque,
                                       virFreeCallback freecb);

  int virConnectDomainEventDeregisterAny(virConnectPtr conn,
                                         int callbackID);

Since different event types can received different data in the callback,
the API is defined with a generic callback. Specific events will each
have a custom signature for their callback. Thus when registering an
event it is neccessary to cast the callback to the generic signature

eg

  int myDomainEventCallback(virConnectPtr conn,
                            virDomainPtr dom,
                            int event,
                            int detail,
                            void *opaque)
  {
    ...
  }

  virConnectDomainEventRegisterAny(conn, NULL,
                                   VIR_DOMAIN_EVENT_ID_LIFECYCLE,
                                   VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback)
                                   NULL, NULL);

The VIR_DOMAIN_EVENT_CALLBACK() macro simply does a "bad" cast
to the generic signature
