According to https://www.ietf.org/rfc/rfc2616.txt 4.2, header names
shall be case insensitive and we are now forced to read headers like
`Content-Length` capitalized.
The problem with that is when a HTTP server responds with a
`content-length` header in lowercase GRUB gets stuck because HTTP
module doesn't know the length of the transmision and the call never
ends.
