* Support curl-like syntax for custom MIME type for files
In order to specify a custom MIME type for file uploads, a syntax
similar to that used by cURL is used so that
http -F test_file@/path/to/file.bin;type=application/zip https://...
forwards the user-provided file type if provided, otherwise falling
back to the usual guesswork out of the file extension.
