Removing a raw header

[yberreby]

Currently, I can insert or overwrite a header by doing, for example:

request_headers.set_raw("Accept-Encoding", vec![b"gzip, deflate".to_vec()]);

But apparently, I cannot remove it, only set it to a different value.
Wouldn't it be useful to add a remove_raw() method to Headers?
Raw headers are very useful if you don't know what headers to send at compile time, for example, or for quick prototyping.

Good call, this would be needed to support XHR's removeHeader method.

removeRequestHeader is unspecc'd, so I don't expect Servo to make use of this.
