IConstDFUprogress::getFileAccessCost is still returning a double.

trivial: don't think this variable name needs/is helped by having suffix "Type", and similar below.

{
CriticalBlock block(parent->crit);
queryRoot()->setPropReal("@fileAccessCost", fileAccessCost);
queryRoot()->setPropInt64("@fileAccessCost", fileAccessCost);

Relaed to comment in ws_fsService.cpp.
The corresponding get function in this class is (unchanged):

    double getFileAccessCost() const
    {
        CriticalBlock block(parent->crit);
        return queryRoot()->getPropInt64("@fileAccessCost");
    }

that looks like a pre-existing bug. It was set as a real, but retrieved as an int (then cast to a double on return).

Costs have been represented as double in some places in the code
and cost_type in other places.  The use of both double and
cost_type internally for costs has made the code more difficult
to understand and maintain.  It has lead to some bugs.

This commit makes all internal representation of cost in the code
as cost_type.  The cost_type is only converted to double when
returning costs externally via ESP services.

should be changed from returning a floating point number to an integer - i.e. return 0;
