Fixed some compiler warnings and errors in test suite found by buildbot

include/ft_global.h:
  Changed string size to 'size_t' (to avoid compiler warnings later)
include/maria.h:
  Changed string size to 'size_t' (to avoid compiler warnings later)
mysql-test/r/show_check.result:
  Don't use logging to tables, as there is no guarantee in which order tables are showed in 'show open tables'
mysql-test/suite/rpl/t/rpl_rotate_logs.test:
  Use HIGH_PRIORITY inserts to avoid problem with concurrent inserts on the slave.
