Advanced file-uploads middleware(s)

Quoting PAStheLoD:

Hi, please consider the issue of input buffering, especially in the case of handling large file uploads. (And trying to show the user transfer the speed for example.)

Also the request parsing should be able to deal with this. (So, for example, via inheriting from a specific class, one could work together with AiP's request handler to set up where to save the files, put stats into memcache or APC cache, or filter on filename, or inspect the beginning of files for some MIME magic.)
