* functions and insert that before feeding the data to fast-import

* somewhat complicated, as we do not know the size of the filter
* result, which we need to know beforehand when writing a git object.
* Since the primary motivation for trying to stream from the working

* binary blobs, they generally do not want to get any conversion, and
* callers should avoid this code path when filters are requested.
