#9037: HTTP API only allows once instance of a particular header

--------------------------+-------------------------------------------------
 When the WP_Http() API parses a response from a request that it's made, it
 parses the headers into an associative array, using the header name as the
 key.

 This is normally fine, but there are some headers (e.g. Set-Cookie) which
 are allowed to be set more than once. In this case, each instance of the
 header encountered overwrites the previous one, so that the headers you
 get back end up only showing the ''last'' instance of that header.

 This patch allows it to handle multiple appearances of each header,
 converting that array entry into an array of values for that header if
 there are more than one seen.

 e.g.
 {{{
 Array
 (
     [set-cookie] => Array
         (
             [0] =>
 SC=RV=99624-702292-13606-284784-700373-665639-658887-358464-700145;

 }}}
