[Libvirt-cim] [PATCH 0 of 9] #2 - Reorganized association provider registration

[Heidi Eckhart]

The provider registration approach - registering one provider 
per subclass (Xen_<classname>Provider, KVM_<classname>Provider)
caused interoperability issues with Pegasus and sfcb. The same
call returned duplicates with sfcb and worked with Pegasus.

Diff to patch #1:
- clarified patch message
- added match_hypervsior_prefix to association's handler functions

Tested for sfcb and Pegasus, but encountered a strange behavior with
Pegasus. Please can someone try to reproduce this on his/her system ?

The following call
wbemain -ac CIM_HostedDependency -noverify 'http://pegasus:pegasus@localhost/root/virt:KVM_HostSystem.CreationClassName="KVM_HostSystem",Name="localhost.localdomain"'
should return
localhost:5988/root/virt:KVM_ResourcePoolConfigurationService.SystemCreationClassName="KVM_HostSystem",SystemName="localhost.localdomain",CreationClassName="KVM_ResourcePoolConfigurationService",Name="RPCS"
localhost:5988/root/virt:KVM_VirtualSystemManagementService.SystemCreationClassName="KVM_HostSystem",SystemName="localhost.localdomain",CreationClassName="KVM_VirtualSystemManagementService",Name="Management Service"
localhost:5988/root/virt:KVM_ComputerSystem.CreationClassName="KVM_ComputerSystem",Name="qemu1"

but the returned results for Pegasus depend on the order, in which the providers Virt_HostedDependency and Virt_HostedService have been called. Either 
localhost:5988/root/virt:KVM_ResourcePoolConfigurationService.SystemCreationClassName="KVM_HostSystem",SystemName="localhost.localdomain",CreationClassName="KVM_ResourcePoolConfigurationService",Name="RPCS"
localhost:5988/root/virt:KVM_VirtualSystemManagementService.SystemCreationClassName="KVM_HostSystem",SystemName="localhost.localdomain",CreationClassName="KVM_VirtualSystemManagementService",Name="Management Service"
is returned if, Virt_HostedService was called first or

localhost:5988/root/virt:KVM_ComputerSystem.CreationClassName="KVM_ComputerSystem",Name="qemu1"
is returned, if Virt_HostedDependency was called first.

Thanks ... Heidi
