pull: Add a compilation progress report.
* guix/build/pull.scm (report-build-progress): New procedure. (p-for-each): Add #:progress parameter. [loop]: Keep track of the number of completed processes. Tail-call PROGRESS at each loop iteration. (build-guix): Add #:debug-port parameter. Use it for verbose messages. Change 'tar' flags to 'xf'. Around 'compile-file' call, bind CURRENT-WARNING-PORT to DEBUG-PORT. * guix/scripts/pull.scm (unpack): Add #:verbose? parameter. [builder]: Pass #:debug-port to 'build-guix'. (guix-pull): Leave CURRENT-BUILD-OUTPUT-PORT unchanged. Pass #:verbose? to 'unpack'.
