multipart/form-data handling in Falcon proposal

Design philosophy

Multipart form handling should be performant, straightforward, and leave full control of the parsing process to the user, i.e. no surprising magic such as automatic creation of large files and saving anything there by default (although tools/helpers may exist to assist in that too).
