Python code generator "generate_source" section that handles
code generation to "free" inherited objects needs to generate
DISPATCH_FREE calls for all extended_by objects.

The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:

1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs          <------> Libvirt Storage Volumes.

The above understanding is based on http://libvirt.org/storage.html.

The operation supported on iSCSI pools includes:

1. List storage pools & volumes.
2. Get XML descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, UUID and path (if applicable).

iSCSI pools does not support operations such as: Create / remove pools
and volumes.

Traverse the whole inheritance hierarchy for dynamic dispatch as it is
already done for the dynamic cast.

Also make AnyType cast errors more verbose.

An ESX server has one or more PhysicalNics that represent the actual
hardware NICs. Those can be listed via the interface driver.

A libvirt virtual network is mapped to a HostVirtualSwitch. On the
physical side a HostVirtualSwitch can be connected to PhysicalNics.
On the virtual side a HostVirtualSwitch has HostPortGroups that are
mapped to libvirt virtual network's portgroups. Typically there is
HostPortGroups named 'VM Network' that is used to connect virtual
machines to a HostVirtualSwitch. A second HostPortGroup typically
named 'Management Network' is used to connect the hypervisor itself
to the HostVirtualSwitch. This one is not mapped to a libvirt virtual
network's portgroup. There can be more HostPortGroups than those
typical two on a HostVirtualSwitch.

the hypervisor and the VirtualEthernetCard for the virtual machines
that are grouped into HostPortGroups.

The currently implemented network driver can list, define and undefine
HostVirtualSwitches including HostPortGroups for virtual machines.
Existing HostVirtualSwitches cannot be edited yet. This will be added
in a followup patch.

Lists available PhysicalNic devices. A PhysicalNic is always active
and can neither be defined nor undefined.

A PhysicalNic is used to bridge a HostVirtualSwitch to the physical
network.

Append "Byte" to set of predefined datatype objects.

Fix addresses two issues:
1. Fix generator code to allow deep copy operation for objects with
   Dynamic_Cast capabilities.
2. Add missing deep copy routine to Long datatype.

Break long lines and change spacing of keyword arguments to match
Python style standards better.

No functional change included.

Instead of specifying the type of the managed object directly specify
the ServiceContent member name. This way the mapping dictionary can be
removed.

Move common code from Property and Parameter into new Member class.

Rename the other base class to Type.

Detect it based on usage as parameter, return type and member of other
object types.

Detect it based on usage as parameter and return type too.

Don't make all object and enum types (de)serializable by default.
Detect this from the input file instead.

Several vSphere API methods are called on global objects like the
FileManager, the PerformanceManager or the SearchIndex. The generator
input file allows to mark such methods and the generator generates
such method in a way that automatically handles marked parameter. This
is done by some special macros. Those were manually written and this
patch moves them to the generator.

Accept all types on deserialization in order to accept all Event subtypes.

This will be used for the upcoming domain event support.

Generate lookup functions for managed object types.

Add CastFromAnyType functions for the String type.

Instead of just reporting that a task failed get the
localized message from the TaskInfo error and include
it in the reported error message.

Implement minimal deserialization support for the
MethodFault type in order to obtain the actual fault
type.

For example, this changes the reported error message
when trying to create a volume with zero size from

  Could not create volume

to

  Could not create volume: InvalidArgument - A specified parameter was not correct.

Not perfect yet, but better than before.

This is more flexible regarding the location of the python binary
but doesn't allow to pass the -u flag. The -i flag can be passed
from inside the script using the PYTHONINSPECT env variable.

This fixes a problem with the esx_vi_generator.py on FreeBSD.

Distinguish between strings as parameters (const char *)
and strings as return values (char **).

Now all storage pool types expose the target path.

Don't rely on summary.url anymore, because its value is different
between an esx:// and vpx:// connection. Use host.mountInfo.path
instead.

Don't fallback to lookup by UUID (actually lookup by absolute path)
in esxVI_LookupDatastoreByName when lookup by name fails. Add a
seperate function for this: esxVI_LookupDatastoreByAbsolutePath

Always call the free function of the base type. The base type
function then dynamically dispatches the call to the free function
for the actual type.

This works for file-backed SCSI disk device with a datastore
related source path.

This will be used to deserialize the response from a call
to esxVI_SearchDatastore_Task properly.

Allows listing existing pools and requesting information about them.

Alter the esxVI_ProductVersion enum in a way that allows to check for
product type by masking.

This will be used in the ESX storage driver in order to handle
the DatastoreInfo type and inheriting types properly.

Generate almost all SOAP method mapping code.

Update the driver code to use the complete paramater list of some methods
that had parameters skipped before.

Improve the ESX_VI__METHOD marco to do automatic output deserialization
based on output occurrence. Also incorporate automatic _this binding and
output pointer check.

Fix invalid code generating in esx_vi_generator.py regarding deep copy
types that contain enum properties.

Add strptime and timegm to bootstrap.conf. Both are used to convert a
xsd:dateTime to calendar time.

Add a testcase of the xsd:dateTime conversion.

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.
