services: web: Remove default certificate and key files for nginx.

If nginx is configured with a ssl-certificate file, and ssl-certificate-key,
it will fail to start unless these exist. To avoid this happening, change the
default to #f.

* gnu/services/web.scm (<nginx-server-configuration>)
  [ssl-certificate,ssl-certificate-key]: Set the defaults to #f.
* gnu/tests/web.scm (%nginx-servers): Remove redundant
  nginx-server-configuration fields.
* doc/guix.texi (Web Services): Update examples and documentation.

gnu, doc, tests: Use ‘bootloader-configuration’ everywhere.

* doc/guix.texi (Proceeding with the Installation): Replace the old-style
‘grub-configuration’ with the newer ‘bootloader-configuration’ syntax.
* gnu/system/examples/vm-image.tmpl: Likewise.
* gnu/system/install.scm (installation-os): Likewise.
* gnu/tests.scm (%simple-os): Likewise.

tests: Add 'git-http' test.

* gnu/tests/version-control.scm (%git-nginx-configuration)
(%git-http-os, %test-git-http): New variables.
(run-git-http-test): New procedure.

tests: cgit: Add a file to the test repository.

* gnu/tests/version-control.scm (README-contents): New variable.
(%make-git-repository): Add a 'README' file to the repo.
(%test-repository-service): New variable.
(%cgit-os): Use it.
(run-cgit-test): Test /test/tree/README and /test/tree/does-not-exist.

tests: messaging: Enable Prosody DIGEST-MD5 auth mechanism.

GNU Freetalk doesn't support SCRAM-SHA-1.

* gnu/tests/messaging.scm (%test-prosody): Override default
disable-sasl-mechanisms value.

tests: install: Increase target-size.

1200 MiB are too small for a btrfs-root-os, thus let increase it.

* gnu/tests/install.scm (run-install): Increase target-size to 2200 MiB.
(%btrfs-root-installation-script): Increase my-root partition size to 2G.

tests: ssh: Make sure we can run executables from PATH.

* gnu/tests/ssh.scm (run-ssh-test): Add tests for running commands in system
and user profile.

tests: install: Estimate the installation system disk size.

1500 MiB are too small for a current system, thus let
system-disk-image estimate the required size.

* gnu/tests/install.scm: (run-install): Pass "#:disk-image-size
  'guess" to system-disk-image.

tests: databases: Add a simple test for MySQL.

Previously, the activation phase for this service caused some systems using it
to not boot. This test checks that it's possible to boot a system using it,
and at least start the service.

* gnu/tests/databases.scm (%mysql-os, %test-mysql): New variables.
  (run-mysql-test): New procedure.

tests: install: Switch to modifying the gc-root-service-type.

Fixes <https://bugs.gnu.org/28600>.
Fixes a regression introduced in
4e854b1814a9216ae7cc90aef4d82fd989a519c3.
Reported by Christopher Baines <mail@cbaines.net>.

* gnu/tests/install.scm (operating-system-with-gc-roots): Use
'simple-service' to extend GC-ROOT-SERVICE-TYPE instead of instantiating
it.

tests: mcron: Adjust use of 'wait-for-file'.

Fixes a regression introduced in
8bd5231485cdeb02078c4294badb3a1e7caa0fe0, whereby returning #<eof> would
no longer work (since #<eof> would be in the cdr of the result, and thus
it would not get converted to a string.)

* gnu/tests/base.scm (run-mcron-test)["root's job with command"]: Pass
  #:read to 'wait-for-file'.
