* guix/ssh.scm (remote-daemon-channel)[redirect]: Remove 'read!' FFI
hack.  Use buffered ports.

Fixes <https://bugs.gnu.org/26008>.
Reported by Myles English <mylesenglish@gmail.com>.

* guix/ssh.scm (retrieve-files*): Move error reporting to...
(report-guile-error, report-module-error): ... here.  New procedures.
* guix/scripts/offload.scm (assert-node-repl): Use 'report-guile-error'.

Fixes <https://bugs.gnu.org/28057>.
Reported by Ricardo Wurmus <rekado@elephly.net>.

* guix/scripts/offload.scm (assert-node-has-guix): Catch
'node-repl-error' and call 'leave'.

* guix/ssh.scm (retrieve-files): Remove the subset of FILES that is
valid in LOCAL.

This fixes a regression in 'retrieve-files*' introduced in
896fec47, whereby (guix scripts offload)
would not read the initial sexp now sent by the remote host via
'store-export-channel'.  This would effectively prevent file retrieval
entirely when offloading.

* guix/ssh.scm (retrieve-files*): New procedure, like former
'retrieve-files' but with an extra #:import parameter.
(retrieve-files): Rewrite in terms of 'retrieve-files*'.
(file-retrieval-port): Make private.
* guix/scripts/offload.scm (transfer-and-offload): Pass #:import to
'retrieve-files*'.
(retrieve-files*): Remove.

* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/bittorrent.scm (transmission)[source]: Use it.

[source]: Remove both patches.

[source, home-page]: Switch to new host.

* gnu/packages/photo.scm (gphoto2): Update to 2.5.15.

* gnu/packages/photo.scm (libgphoto2): Update to 2.5.16.

Also add the non-archive URL, which was probably the intention of commit
8d479d27.  Better late than never.

* gnu/packages/patchutils.scm (colordiff): Update to 1.0.18.

* gnu/packages/patches/libvorbis-CVE-2017-14632.patch,
gnu/packages/patches/libvorbis-CVE-2017-14633.patch: New files.
* gnu/local.mk (dist_patch_DATA): Add them.
