* guix/scripts/substitute.scm (<cache>): Rename to...
(<cache-info>): ... this.
(open-cache): Rename to...

(open-cache*): Remove.
(cache-narinfo!): Take a URL instead of a <cache> as the first parameter.
(fetch-narinfos): Likewise. Call 'download-cache-info'. Remove use of
'force'.

* guix/scripts/substitute.scm (http-multiple-get): When RESP has "Connection:
close", consume HEAD anyway; always call PROC to read from BODY.

Previously, code using directly (guix build download) was still affected
by <http://bugs.gnu.org/15368>. This includes source derivations, the
'guix download' command, and (guix gnu-maintenance).
'guix substitute' was unaffected since it used (guix http-client), which
already had the fix.
* guix/http-client.scm (open-socket-for-uri): Remove.
(http-fetch): Remove #:buffered? argument to 'open-socket-for-uri';
use 'setvbuf' instead.
* guix/scripts/substitute.scm (fetch): Likewise.
* guix/build/download.scm (open-socket-for-uri): New procedure, taken
from guix/http-client.scm, but without the #:buffered? parameter.
In practice we would not leak much since we reconnect after ~100
requests (with nginx running on hydra.gnu.org.)
* guix/scripts/substitute.scm (http-multiple-get): Call 'close-port'
before 'connect'.
