To enable the check for the client's given object path in ElementCapabilities, changes
to the ComputerSystem and AllocationCapabilities provider have been necessary.
Diff to patch #1:
- added a new function to libcmpiutil - cu_validate_ref(ref, inst) - that does the check
between the system instance and the client given instance
- get_domain() is now using the new libcmpiutil function
- the parameter CMPIInstance **inst is now used to "configure" get_domain(); for
internal usage the inst is returned and for external usage this can be ignored by setting
it to NULL
- validate_domain_ref() is now only an interface name for the client
- removed patch unrelated changes in patch 2
- reworked logic to return instance(s)
Diff to patch set #2:
- removed validate_domain_ref() and made get_domain() external
- fixed coding style in AllocationCapabilities
- fixed inst_list to catch the returned instances
- adopted changes to patch 1 and 2 to patch 3
- check for NULL connection in EC now

Make alloc_cap_instances() available for external use by EC
The association provider ElementCapabilities needs the
enum_alloc_cap_instances() function to access to the list
of available AllocationCapabilities. These are returned
by the additional inst_list parameter.

EC: Validation of client given object path missing
The validation of the client's given ResourcePool object
path is missing. Instead the submitted InstanceID is
taken as value for the AllocationCapabilities InstanceID.
wbemain -ac CIM_ElementCapabilities

for internal usage the inst is returned and for external usage this can be ignored by
setting it to NULL
- validate_domain_ref() is now only an interface name for the client
- removed patch unrelated changes in patch 2
- reworked logic to return instance(s)
Diff to patch set #2:
- removed validate_domain_ref() and made get_domain() external
- fixed coding style in AllocationCapabilities
- fixed inst_list to catch the returned instances
- adopted changes to patch 1 and 2 to patch 3
- check for NULL connection in EC now
No complaints on this set.
