   the connection was closed

   any data was sent as part of it
 o only probe for working ipv6 once and then re-use that info for further
   requests
 o requests that are asked to bound to a local interface/port will no longer
   wrongly re-use connections that aren't
 o libcurl.m4: Add missing quotes in AC_LINK_IFELSE
 o progress output: don't print the last update on a separate line
