Also define ESX_ERROR and ESX_VI_ERROR in a central place, instead of
defining them in each source file.

Add ESX_ERROR and ESX_VI_ERROR to the msg_gen_function list in cfg.mk.

Update po/POTFILES.in accordingly.

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for a running domain that would be by definition outdated data.

virParseVersionString uses virStrToLong_ui instead of sscanf.

This also fixes a bug in the UML driver, that always returned 0
as version number.

Introduce STRSKIP to check if a string has a certain prefix and
to skip this prefix.

virStrToLong* guarantees (via strtol) that the end pointer will be set
to the point at which parsing stopped (even on failure, this point is
the start of the input string).

conditional.

* src/esx/esx_vi_types.h: Filter through cppi.

The Python script generates the mappings based on the type descriptions
in the esx_vi_generator.input file.

This also improves the inheritance handling and allows to get rid of the
ugly, inflexible, and error prone _base/_super approach. Now every struct
that represents a SOAP type contains a _type member, that allows to
recreate C++-like dynamic dispatch for "method" calls in C.

The current virDomainAttachDevice API can be (ab)used to change
the media of an existing CDROM/Floppy device. Going forward there
will be more devices that can be configured on the fly and overloading
virDomainAttachDevice for this is not too pleasant. This patch adds
a new virDomainUpdateDeviceFlags() explicitly just for modifying
existing devices.

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

Used in esxDomainLookupByName and to be used in esxDomainDefineXML later.

If esxVI_String_DeepCopyValue or esxVI_SelectionSpec_AppendToList fail
then selectionSpec would leak. Add a free call in the failure path to
fix the leak.

Replace 'method' with 'function' and get the filename's suffix right.

This is actually a consequence of the reworked required parameter
checking: Unify the required parameter check into a Validate function
instead of doing it separately im the (de)serialization part.

The required parameter checking for the mapped methods parameter was
done in the (de)serialize functions before. Now it's explicitly done
in the mapped method itself.

Also add vol wiping to ESX storage driver struct

for f in $(git ls-files '*.[ch]') ; do

Implementation of domain{Attach,Detach}DeviceFlags handlers
in the drivers.

* src/esx/esx_vi_types.c: Include <stdint.h>.

* src/conf/domain_conf.c: add defaults for the video device
* src/esx/esx_vmx.[ch]: add VNC support to the VMX handling
* tests/vmx2xmltest.c, tests/xml2vmxtest.c: add tests for the VNC support

Before the driver assumed that there is always a domain part. That's
not true. Now the domain part is handled as optional.

This stops libvirt from probing for a libvirtd on the ESX server and
sets the base for the implementation of the secondary drivers.

Currently only the faultcode and faultstring are deserialized, the
detail part is ignored. The implementation of many new SOAP types
would be necessary to deserialize the detail part correctly. As an
intermediate solution the raw response is dumped to the debug log.

The MAC addresses with 00:50:56 prefix are split into several ranges:

  00:50:56:00:00:00 - 00:50:56:3f:ff:ff  'static' range (manually assigned)
  00:50:56:80:00:00 - 00:50:56:bf:ff:ff  'vpx' range (assigned by a VI Client)

Erroneously the 'vpx' range was assumed to be larger and to occupy the
remaining addresses of the 00:50:56 prefix that are not part of the 'static'
range.

00:50:56 was used as prefix for generated MAC addresses, this is not possible
anymore, because there are gaps in the allowed ranges. Therefore, change the
prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway.

Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option
to false in case the MAC address doesn't fall into any predefined range.

* src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29
* src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC
  addresses

The data passed to the callback is not guaranteed to be zero terminated,
take care of that by coping the data and adding a zero terminator.

Also dump the data for other types than CURLINFO_TEXT.

Set CURLOPT_VERBOSE to 1 so the debug callback is called when enabled.
