this is basically a replacement to the metaserver_get_info - idea being that when metaserver 1 support goes away, just yank that entire function and replace it with this.

Returns: best I can tell, always returns 0

size_t metaserver2_writer	(	void *	ptr,
		size_t	size,
		size_t	nmemb,
		void *	data
	)

Curle doesn't really have any built in way to get data from the URL into string data - instead, we get a blob of data which we need to find the newlines, etc from. Curl also provides the data in multiple calls if there is lots of data, and does not break the data on newline, so we need to store the extra (unprocessed) data from one call to the next.

Parameters

ptr	pointer to data to process.
size
nmemb	the size of each piece of data, and the number of these elements. We always presume the data is byte sized, and just multiple these together to get total amount of data.
data	user supplied data pointer - in this case, it points to a buffer which is used to store unprocessed information from one call to the next.

Returns: Number of bytes processed. We always return the total number of bytes supplied - returning anything else is an error to CURL

Sees if we are gathering data or not. Note that we don't have to check to see what update methods are being used - the is_running flag is initialized to zero no matter if we are using that method to get the data, and unless we are using ms1 or ms2, the is_running flag will never get changed to be non-zero.
