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.
