a_Digest_authorization_hdr()

char * a_Digest_authorization_hdr	(	AuthRealm_t *	realm,
		const DilloUrl *	url,
		const char *	digest_uri
	)

Construct Digest Authorization header.

Field ordering: furaisanjin reports that his DVD recorder requires the order that IE happens to use: "username, realm, nonce, uri, cnonce, nc, algorithm, response, qop". It apparently doesn't use "opaque", so that's been left where it already was.
