Marko Mäkelä 2f00b73a4b MDEV-11985 Make innodb_read_only shutdown more robust
If InnoDB is started in innodb_read_only mode such that
recovered incomplete transactions exist at startup
(but the redo logs are clean), an assertion will fail at shutdown,
because there would exist some non-prepared transactions.

logs_empty_and_mark_files_at_shutdown(): Do not wait for incomplete
transactions to finish if innodb_read_only or innodb_force_recovery>=3.
Wait for purge to finish in only one place.

trx_sys_close(): Relax the assertion that would fail first.

trx_free_prepared(): Also free recovered TRX_STATE_ACTIVE transactions
if innodb_read_only or innodb_force_recovery>=3.

Also, revert my earlier fix to MySQL 5.7 because this fix is more generic:

Bug#20874411 INNODB SHUTDOWN HANGS IF INNODB_FORCE_RECOVERY>=3
SKIPPED ANY ROLLBACK

trx_undo_fake_prepared(): Remove.

trx_sys_any_active_transactions(): Revert the changes.
