Update the comment to make clear that we ask for 14 minutes worth of
jobs on purpose so at most three parallel cron jobs are running.

It's basically the same as for console.php now.

Just to avoid users from trying this with a to new (untested) php version

* Moved the check logic to 1 place
* All directly callable scripts just require this on top
* exit hard (-1) so we know scripts won't continue
* Return status 500 so no sync clients will try fancy stuff

There was a setting to disable the last execution of cron. There is no known
problem with this write access and it was also questioned when this feature
was build in https://github.com/owncloud/core/pull/7689#issuecomment-38264707



Recently there was also a bug report about a non-visible last cron execution
(#6088) - let's better remove this.

similar to the console.php

Single user mode basically disables WebDAV, OCS and cron execution. Since
we heavily rely on WebDAV and OCS also in the web UI it's basically useless.
An admin only sees a broken interface and can't even change any settings nor
sees any files. Also sharing is not possible.

As this is at least the case since Nextcloud 9 and we haven't received any
reports for this it seems that this feature is not used at all so I removed it.

The encryption commands now rely on the well tested maintenance mode.

Because some cron jobs do not always properly clean up their FS usage
and others might not clean up before setting up the FS, this could
cause potential side effects.

To make sure we exclude side effects, we tear down the FS between cron
jobs.

nextcloud by default uses the `/config/` directory in the source/application tree for its config file(s).
with this commit that directory can be overridden by the `NEXTCLOUD_CONFIG_DIR` environment variable.

in uwsgi, you would use the option `--env "NEXTCLOUD_CONFIG_DIR=/tmp/nx-config/"`
in apache `SetENV …`
and the cli command can be run with: `NEXTCLOUD_CONFIG_DIR=/tmp/nx-config ./occ` (or just use `export` once in the
shell).

NEXTCLOUD_CONFIG_DIR can be supplied with or without the trailing slash (`/`), but in all cases `$configDir` will have
it automatically added if needed.

The other changes are several occurrences of `OC::$SERVERROOT . '/config'` to `OC::$configDir`.

* the setup check is still there

* makes debugging easier

that I noticed while looking at some code.

* method code is now in the static public namespace (5 sloc)
