substitute: Cache and reuse connections while substituting.
That way, when fetching a series of substitutes from the same server(s), the connection is reused instead of being closed/opened for each substitutes, which saves on network round trips and TLS handshakes. * guix/http-client.scm (http-fetch): Add #:keep-alive? and honor it. * guix/progress.scm (progress-report-port): Add #:close? parameter and honor it. * guix/scripts/substitute.scm (at-most): Return the tail as a second value. (fetch): Add #:port and #:keep-alive? and honor them. (%max-cached-connections): New variable. (open-connection-for-uri/cached, call-with-cached-connection): New procedures. (with-cached-connection): New macro. (process-substitution): Wrap 'fetch' call in 'with-cached-connection'. Pass #:close? to 'progress-report-port'.
