Bug 711166
Partitioned tables are not correctly handled by the --databases, --include,
--tables-file options of innobackupex, and by the --tables and
--tables-file options of xtrabackup.
Solution is to remove partition suffix (#P#...) before doing filtering.
Testcases cover variants of using filtering options with MyISAM and
InnoDB tables (to test both innobackupex and xtrabackup) with either stream
mode turned on and turned off.

Since last MP request:
 added --include option handling
 added more testcases
