jextract generates downcallHandles where I need upcallStubs

[Sebastian Stenzel]

Hi Maurizio,

I just managed to build and test it myself and can confirm that the function interfaces get generated now.  :-)

I will give a panama-based FUSE binding a try in the next couple of weeks. I already achieved very promising results earlier this year (before jextract was based on foreign memory and foreign linker API).

Have a nice holiday season!
Sebastian
