This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
For each translation file available, create a module for cockpit containing the translations. We only need these modules to initialize the locale data within cockpit and to provide translations for the manifest label, but just include the entire .po file anyway so that we don't need to do anything special. po2json and po.empty.js are copied from the cockpit sources, and handle converting .po files into modules in the format that cockpit requires. Despite the name, the data format is very much not JSON, so beware if attempting to modify the scripts. po.empty.js is modified from the cockpit source to include an eslint-disable comment. In main.js, check if we are running within cockpit, and if so use cockpit's language information to select the messages to use with react-intl.
