Release 2 5 pg stop backup decomposition2 (#387)
* Rename pg_checksum_enable() to pg_is_checksum_enabled* Remove unused instanceState from pg_start_backup()* Refactor wait_wal_lsn(): remove unused pgBackup * parameter and replace InstanceState * with simple directory string* Refactor pg_stop_backup(): remove useless conn variable* Make some functions and variables (from backup.c) accessible from other compilation units* Remove some references to global stream_wal variable* Remove unused variable externaldir* Yet another split of pg_stop_backup(): separate verification of stop_lsn into wait_wal_and_calculate_stop_lsn()* Create pfilearray_clear_locks() helper function
