next operation.
Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
* xtrabackup no longer support --compact
* wsrep_sst_mysqldump wasn't always using --default-file
* wsrep_sst.cc overquoted --default-file for wsrep_sst_mysqldump
also remove redundant lines config and test lines, compiler warnings,
and mark big tests as big.
