I talked to Bultje a bit on IRC and he wanted a small program to test
the patches with. I'm attaching it here for anyone else that might be
interested.

It's a small patch to one of the libmicrohttpd examples
(fileserver_example.c) that adds basic handling of Range/Content-Range.
To compile, svn checkout https://ng.gnunet.org/svn/libmicrohttpd/ ,
apply the patch and install in the usual fashion. Then run
src/examples/fileserver_example in a folder with some test files on say
port 8888. Finally, ffplay http://localhost:8888/foo.avi before and
after applying the patch. You'll see that it won't seek properly without
the patch.
