tests: Fork and exec a new Guile for the marionette REPL.

By merely forking PID 1, details from PID 1 (shepherd) would leak into
the marionette process, such as the set of modules in scope and state
inherited from the shepherd process (<service> instances, fibers,
etc.).  Running a fresh Guile instance avoids that.

* gnu/tests.scm (marionette-program): New procedure.
(marionette-shepherd-service): Change 'start' to use
'make-forkexec-constructor', and run the result of 'marionette-program'.

tests: Use the client 'start-service' procedure.

The previous code worked "by chance": 'start' from (shepherd service)
happened to be in scope because the marionette REPL is created by a mere
'primitive-fork', and 'start' happened to kinda work.

* gnu/tests/base.scm (run-basic-test): Use 'start-service' from (gnu
services herd), not 'start' from (shepherd service), which is not
supposed to work.
* gnu/tests/install.scm (run-install): Likewise.

services: herd: 'load-services/safe' is synonymous with 'load-services'.

This is a followup to 547965aa27b6a09cadf42130b7ec7db3f1aee61f.

* gnu/services/herd.scm (load-services/safe): Make an alias for
'load-services'.

services: nscd: Depend on syslogd.

This gets rid of nscd debug messages on the console at boot time.

* gnu/services/base.scm (nscd-shepherd-service): Add dependency on
'syslogd'.

services: postgresql: Add default package.

* gnu/services/databases.scm (<postgresql-configuration>)[postgresql]:
Add default value, moved from...
(postgresql-service-type)[default-value]: ... here.

* gnu/services/dns.scm (knot-shepherd-service): Add 'actions' field.

services: rsync: Add 'configuration' action.

* gnu/services/rsync.scm (rsync-shepherd-service): Add 'actions' field.

services: redis: Add 'configuration' action.

* gnu/services/databases.scm (redis-shepherd-service): Add 'actions'
field.

services: mysql: Add 'configuration' action.

* gnu/services/databases.scm (mysql-shepherd-service): Add 'actions'
field.

gnu: freerdp: Update to 2.2.0 [security fixes].

This fixes CVE-2022-39316, CVE-2022-39317, CVE-2022-39318, CVE-2022-39319,
CVE-2022-39320, CVE-2022-41877, CVE-2022-39347, CVE-2022-39282,

* gnu/packages/rdesktop.scm (freerdp): Update to 2.2.0.
[arguments]: Use gexps.  Do not set DOCBOOKXSL_DIR in #:configureflags.

services: syslog: Log auth.info to /var/log/secure in default configuration.

This causes authentication failures such as those generated by SSH brute force
attacks to appear in /var/log/secure, which is picked up by tools such as
fail2ban.

* gnu/services/base.scm (%default-syslog.conf): Add a auth.info selector for
the /var/log/secure log.

Series-to: 62802@debbugs.gnu.org

services/syslog: Strip leading white space indent in syslog.conf.

This is a cosmetic change.

* gnu/services/base.scm (%default-syslog.conf): Add a comment referencing the
documentation.  Strip the extraneous leading trailing white space indent.

services: syslog: Add a reload action.

* gnu/services/base.scm (syslog-service-type) [actions]: Add a reload action.
* doc/guix.texi (Base Services): Document it.

services: syslog: Move configuration to /etc/syslog.conf.

Having the configuration live at a static location makes it possible to
hot-reload it.

* gnu/services/base.scm (syslog.conf): New variable.
(syslog-etc, syslog-shepherd-service): New procedures.
(syslog-service-type): Rewrite using the above new variable and procedures,
extending etc-service-type with its configuration file.

gnu: bppsuite: Update to 2.4.1.

* gnu/packages/bioinformatics.scm (bppsuite): Update to 2.4.1.
