* gnu/packages/version-control.scm (subversion): Use the http:// URL
to work around <http://bugs.gnu.org/14884>. Reported by Mark Weaver

* guix/scripts/package.scm (guix-package)[process-actions](same-package?):
New procedure. Use it instead of `alist-delete' when filtering out
duplicate packages from the profile.
This fixes a bug whereby a command like
guix package -e '(@@ (gnu packages base) gnu-make-boot0)'
would only succeed when the outputs of that package are available, and
otherwise fail with "/nix/store/... is not valid".
* guix/scripts/package.scm (guix-package)[process-action](package->tuple):
Leave P as is in the result. Move `package->tuple' call from INSTALL*
to INSTALL.
* guix/gnu-maintenance.scm (latest-release): Add `ftp-close' and
`ftp-open' keyword parameters.
* guix/scripts/package.scm (ftp-open*): New variable.
(check-package-freshness): Call `latest-release' with `ftp-open*' and
a no-op procedure.
* gnu-system.am (dist_patch_DATA): Add it.

* gnu/packages/plotutils.scm (plotutils): Add
`plotutils-libpng-jmpbuf.patch' as an input, and apply it.
* guix/scripts/substitute-binary.scm (%regexp-exec-mutex, string->uri):
Remove.
(regexp-exec): Replace this global binding by a thread-safety wrapper.
(fields->alist): Remove `with-mutex', and directly alias `recutils->alist'.
* guix/gnu-maintenance.scm (%gsrc-package-list-url): New variable.
(<gnu-package-descriptor>): Add `doc-description' field.
(official-gnu-packages)[group-package-fields]: Rename to...
[read-records]: ... this. Reverse the result.
[gsrc-description]: New procedure.
Add the "description" field to the alist passed to `alist->record'.
* guix/records.scm (%recutils-plus-rx): New variable.
(recutils->alist): Use it to read + lines.
* tests/records.scm ("recutils->alist with + lines"): New test.
* guix/gnu-maintenance.scm (official-gnu-packages)[group-package-fields]:
Rewrite in terms of `recutils->alist'. Remove `state' parameter.
Specify "doc-url" and "language" as multiple-value keys in the
`alist->record' call.
* guix/records.scm (%recutils-field-rx): New variable.
(recutils->alist): New procedure, formerly known as `fields->alist'.
* guix/scripts/substitute-binary.scm (fields->alist): Use it.
* tests/records.scm ("recutils->alist"): New test.
