Using locked operations (insertion & removal) on the list of queued
devices installations is necessary, because these operations are done
concurrently by two different threads: PnpEventThread() and
DeviceInstallThread().
Addendum to commit b2aeafca (r24365).
NDK: Define PLUGPLAY_CONTROL_PROPERTY_DATA.Properties and PLUGPLAY_CONTROL_DEVICE_RELATIONS_DATA.Relations values.
NTOSKRNL: Map PLUGPLAY_CONTROL_PROPERTY_DATA.Properties values to IoGetDeviceProperty properties and add (dummy) code for unsupported cases.
UMPNPMGR: Use PLUGPLAY_CONTROL_PROPERTY_DATA.Properties values in PNP_GetDeviceRegProp.
