[inputs]: Add mit-krb5.  Add bash-minimal inconditionally.

Justification: the test also failed on the CI for x86_64 and caused an
evaluation to fail.

globally.

gnu: mit-krb5: Absorb 1.19.2 graft.

(cmake)[source]: Delete field, updating the package to 3.21.3 also.  Remove
trailing #t.
(%common-disabled-tests) <CMake.FileDownload>: Add test.

gnu: graphviz: Update to 2.49.0.

* gnu/packages/graphviz.scm (graphviz): Update to 2.49.0.

gnu: inkscape: Remove the legacy 0.92 version.

The older 0.92 Inkscape package was previously kept because of problems
building lib2geom on the ARM architectures.  As this no longer appears to be a
problem (tested on the overdrive1 machine), finally replace the older Inkscape
by the newer 1.1 release.

* gnu/packages/inkscape.scm (inkscape-1.1): Delete variable, moving the
package definition to...
(inkscape): ... the now single inkscape variable.  Remove trailing #t.
[tests?]: Remove.
[phases]{generate-gdk-pixbuf-loaders-cache-file}: Add phase.

gnu: rest: Use libsoup-minimal.

This is needed to prevent a dependency cycle between Inkscape and GTK+.

* gnu/packages/gnome.scm (rest)[propagated-inputs]
{libsoup}: Use the minimal variant.

gnu: gusb-minimal: Introduce minimal variant.

This is needed to prevent a dependency cycle between Inkscape and GTK+.

* gnu/packages/gnome.scm (gusb-minimal): New variable.
[configure-flags]: Disable docs.
[native-inputs]: Remove gtk-doc.
(gusb): Rewrite in terms of gusb-minimal.
[configure-flags]: Enable docs.
[native-inputs]: Add gtk-doc.

gnu: libcloudproviders-minimal: Introduce minimal variant.

* gnu/packages/gnome.scm (libcloudproviders-minimal): New minimal variant that
doesn't require Inkscape to be built (through gtk-doc).
[source]: Adjust URI.
[outputs]: Remove field.
[configure-flags]: Disable introspection, docs and vala bindings.
[phases]{move-doc}: Move phase to ...
(libcloudproviders)[phases]: ... here.
Rewrite in terms of libcloudproviders-minimal.  The "doc" output is moved
here.
[configure-flags]: Clear inherited flags and enable doc.
* gnu/packages/gtk.scm (gtk+)[inputs]{libcloudproviders}: Use the minimal
variant to prevent a cycle with Inkscape.

gnu: colord-minimal: Introduce minimal variant.

* gnu/packages/gnome.scm (colord-minimal): New minimal variant that doesn't
require Inkscape to be built (through gtk-doc).  Remove trailing #t.
[configure-flags]: Disable docs and manpage generation.  Sort order.
(colord): Rewrite in terms of colord-minimal.
[configure-flags]: Enable manpages and bash completion.
[phases]{fix-bash-completion-dir}: New phase.
[native-inputs]: Add bash_completion, docbook-xsl-ns and libxml2.
* gnu/packages/gtk.scm (gtk+)[inputs]{colord}: Use the colord-minimal variant
to prevent a cycle with Inkscape.

gnu: Add docbook-xsl-ns.

* gnu/packages/docbook.scm (docbook-xsl-ns): New variable.

gnu: json-glib-minimal: Introduce minimal variant.

* gnu/packages/gnome.scm (json-glib-minimal): New variable.
[source]: Adjust URI.
[outputs]: Move doc output to...
(json-glib)[outputs]: ... here.  Rewrite in terms of json-glib-minimal.
* gnu/packages/gtk.scm (gtk+): Use json-glib-minimal to break a cycle with
Inkscape.

gnu: lsof: Fix indentation.

* gnu/packages/lsof.scm (lsof): Fix indentation.

gnu: lsof: Disable the LTlock test.

Fixes <https://issues.guix.gnu.org/44953>.

* gnu/packages/lsof.scm (lsof)[phases]: Remove trailing #t.
{disable-failing-tests}: Disable the LTlock test.

gnu: at-spi2-atk: Break a dependency cycle between GTK+ and Inkscape.

* gnu/packages/gtk.scm (at-spi2-atk)
[propagated-inputs]: Replace at-spi2-core with at-spi2-core-minimal.

gnu: at-spi2-core: Reverse inheritance relationship with minimal variant.

Since the minimal variant is here to stay, this should make things easier to
maintain.

* gnu/packages/gtk.scm (at-spi2-core-minimal): Rewrite after removing
inheritance, making it the base minimal package, with no documentation-related
inputs or build phases.
(at-spi2-core): Rewrite definition, inherit from the above minimal variant,
adding the documentation-related inputs and build phases.

gnu: meson: Patch to allow installing to independent prefixes.

Meson goes to lengths at preventing installation to directories outside of the
main installation prefix.  This isn't convenient or desirable in Guix; patch
it out using a patch maintained by Nix.

* gnu/packages/patches/meson-allow-dirs-outside-of-prefix.patch: Add patch.
* gnu/local.mk (dist_patch_DATA): Register it.
* gnu/packages/build-tools.scm (meson): Use it.
