This function is only for use by Software Install.
As part of the fix for defect INC069526, we added a check in apparc. We check if the application has
been installed before adding it to the apparc db. A side-effect of this fix is that it is not possible
to launch applications that are being installed from the installation process itself. This is a regresssion.
To fix this regression we added this function. It allows Software Install to specify a list of registration
files that need to be included in apparc's list even if they have not been marked as installed in the
SISRegistry or JavaRegistry. The list of registration files is cleared once Software Install notifies
(via P&S) the end of the installation (whether successful or not).
The function also forces a rescan and only returns when this rescan is complete. This is because
Software Install needs to be sure the registration files have been added to apparc's list before
trying to launch the recently installed applications.
@param aRegFiles The list of registration files for which the SISRegistry check must be ignored.
