Feature: #73042 - Introduce native support for Symfony Console

See forge#73042


TYPO3 supports the Symfony Console component out-of-the-box now by providing a new Command Line script located in typo3/sysext/core/bin/typo3. On TYPO3 instances installed via Composer, the binary is linked into the bin-dir, e.g. bin/typo3.

The new binary still supports the existing command-line arguments when no proper Symfony Console command was found as a fallback.

Registering a command to be available via the typo3 command line tool works by putting a Configuration/Commands.php file into any installed extension. This lists the Symfony/Console/Command classes to be executed by typo3 is an associative array. The key is the name of the command to be called as the first argument to typo3.

A required parameter when registering a command is the class property which should inherit from Symfony's base Command class.

A Configuration/Commands.php could look like this:

return [
    'backend:lock' => [
        'class' => \TYPO3\CMS\Backend\Command\LockBackendCommand::class
    'referenceindex:update' => [
        'class' => \TYPO3\CMS\Backend\Command\ReferenceIndexUpdateCommand::class

An example call could look like:

bin/typo3 backend:lock http://www.mydomain.com/maintenance.html

For a non-Composer installation:

typo3/sysext/core/bin/typo3 backend:lock http://www.mydomain.com/maintenance.html


Using Symfony Commands and calling typo3 instead of using typo3/cli_dispatch.phpsh is now the preferred way for writing command line code.
