* Add repo-sync-releases admin command Will help recovering corrupted database, see #3247 * Load repos in chunks of 10, exit with error if unable to get a list, scan private repos, fix typo * Fix debug output about num releases * Introduce RepositoryListDefaultPageSize constant, set to 64 Use it from the new admin command * Use RepositoryListDefaultPageSize in more places * Document RepositoryListDefaultPageSize
