Bug Description

Xtrabackup crashes when trying to remove absent table from InnoDB data
dictionary.

2014-07-04 18:11:07 7ffff7fe9720 InnoDB: Operating system error number 2 in a file operation.
InnoDB: The error means the system cannot find the path specified.
InnoDB: If you are installing InnoDB, remember that you must create
InnoDB: directories yourself, InnoDB does not create them.
InnoDB: Could not find a valid tablespace file for 'raptor/verify_queue'. See http://dev.mysql.com/doc/refman/5.6/en/innodb-troubleshooting-datadict.html for how to resolve the issue.
InnoDB: It will be removed from the data dictionary.

Xtrabackup crashed while tried to delete unused tables. purge_sys if not initialized. Seems to be specific to innodb56. Related parts of code:
trx_sys_init_at_db_start invoked before trx_purge_sys_create:
comment from srv0start.cc:
ib_bh = trx_sys_init_at_db_start();
n_recovered_trx = UT_LIST_GET_LEN(trx_sys->rw_trx_list);
/* The purge system needs to create the purge view and
therefore requires that the trx_sys is inited. */
trx_purge_sys_create(srv_n_purge_threads, ib_bh);
At the same time trx_lists_init_at_db_start invokes trx_resurrect_table_locks, which has been introduced in MySQL 5.6 (revno: 5045). Purpose of trx_resurrect_table_locks to be discovered.
