BUG# 15408 Partitions: subpartition names are not unique

THis patch goes along with 1.2098.23.1 to form the complete patch


libmysqld/Makefile.am:
  added partition_info.cpp   to libmysqld sources
sql/ha_ndbcluster.cc:
  using the new member versions of these
sql/sql_partition.cc:
  using the member version of is_sub_partitioned
