This reverts commit 17a53aec.

This breaks building vim on ARM architectures.

* gnu/packages/bioinformatics.scm (minimap2)[arguments]: Adjust
configure-flags to be better per-architecture.
[source]: Add patch.
* gnu/packages/patches/minimap2-aarch64-support.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register it.

* gnu/packages/bioinformatics.scm (minimap2)[arguments]: Use
cc-for-target.

* gnu/packages/emacs-xyz.scm (emacs-with-editor): Update to 3.0.2.
[propagated-inputs]: Changed emacs-dash to emacs-async.

* gnu/services/base.scm (shepherd-discover-action): New procedure,
(guix-shepherd-service)[<actions>]: add it,
[<start>]: honor it.
* doc/guix.texi (Invoking guix-daemon): Document it.

There are plenty of options supported that the Guix configuration record
doesn't help you with, so add this field to allow users to do their own thing.

* gnu/services/monitoring.scm (<prometheus-node-exporter-configuration>): Add
extra-options field.
(prometheus-node-exporter-shepherd-service): Handle the extra options.
* doc/guix.texi (Prometheus Node Exporter Service): Document this.

* gnu/services/monitoring.scm (<prometheus-node-exporter-configuration>): Add
textfile-directory.
(prometheus-node-exporter-textfile-directory,
prometheus-node-exporter-activation): New procedures.
(prometheus-node-exporter-shepherd-service): Pass
--collector.textfile.directoryto the service.
(prometheus-node-exporter-service-type): Extend the activation service type.
* doc/guix.texi (Prometheus Node Exporter Service): Document.

* doc/guix.texi (Prometheus Node Exporter Service): Simplify the example.

This makes the logs easier to find and read.

* gnu/services/monitoring.scm (prometheus-node-exporter-shepherd-service):
Pass #:log-file to make-forkexec-constructor.

So it doesn't run as root, and because this will help with the textfile
exporter.

* gnu/services/monitoring.scm (%prometheus-node-exporter-accounts): New
variable.
(prometheus-node-exporter-shepherd-service): Use the relevant user and group.
(prometheus-node-exporter-service-type): Extend the account service type.

Add relevant exports, as well as a comment to better indicate where the
relevant code starts.

* gnu/services/monitoring.scm (prometheus-node-exporter-service-type):
Capitalise Prometheus.

* gnu/packages/video.scm (rav1e): Update to 0.3.4.
[arguments]: In cargo-inputs replace rust-aom-sys-0.1 with 0.2,
rust-nasm-rs-0.1 with 0.2.
