Alexander KukushkinandGitHub 3161f31088 Enhanced sync connections check (#2524) ...

When `synchronous_standby_names` GUC is changed PostgreSQL nearly immediately starts reporting corresponding walsenders as synchronous, while in fact they maybe didn't reach this state yet. To mitigate this problem we memorize current flush lsn on the primary right after change of `synchronous_standby_names` got visible and use it as an additional check for walsenders.
The walsender will be counted as truly "sync" only when write/flush/replay_lsn on it reached memorized LSN and the `application_name` is known to be a part of `synchronous_standby_names`.

The size of PR mostly related to refactoring and moving the code responsible for working with `synchronous_standby_names` and `pg_stat_replication` to the dedicated file.
And `parse_sync_standby_names()` function was mostly copied from #672.
