Routine Description:

    This callback routine is used with SetupScanFileQueue to findout the
    dependent files and ICM files associated in an INF. All files going to the
    printer driver directory are dependent files in DRIVER_INFO_6, and all
    files goint to the Color directory are ICM files.

    We use SetupScanFileQueue twice. We find the size of the buffers required
    for the multi-sz fields in the first pass. After allocating buffers of size
    found in first pass second pass is used to copy the strings and build the
    multi-sz fields.

Arguments:

    pContext        : Gives the SCAN_INFO structure
    Notification    : Ignored
    Param1          : Gives the target file name
    Param2          : Ignored

Return Value:
    Win32 error code

Routine Description:
    Findout the dependent files for the DRIVER_INFO_6 and the ICM files

    This is done by simulating the install operation by create a setup
    queue to do the install operations and scanning the queue to find out
    where files are getting copied to

    Dependent files are those getting copied to driver scratch directory
    without including other DRIVER_INFO_6 fields like pDriverPath. For Win95
    case all files getting copied to the driver directory are dependent files.

    ICM files are those getting copied to the color directory

Arguments:
    hInf                    : INF handle
    bWin95                  : TRUE if it is a Win95 INF

    pcchSize                : Size needed for DRIVER_INFO_6 and strings in it
