- Implement a common property handler for filter property requests

Browse source 
- Always queue a work item for pin creation requests
- Handle KSPROPERTY_PIN_DATAFLOW, KSPROPERTY_PIN_DATARANGES, KSPROPERTY_PIN_INTERFACES, KSPROPERTY_PIN_MEDIUMS, KSPROPERTY_PIN_COMMUNICATION, KSPROPERTY_PIN_CATEGORY,  qKSPROPERTY_PIN_NAME, KSPROPERTY_PIN_GLOBALCINSTANCES, KSPROPERTY_PIN_CINSTANCES, KSPROPERTY_PIN_NECESSARYINSTANCES
- Fix several bugs in property copying code
- Change the pin creation path in sysaudio in order to have client information as this was previously not available (see DPRINT using hack)
- Close file handels in wdmaud / sysaudio
- set Iostatus before queing an irp as the irp might complete before accessing status io
