BUG#15408: Partitions: subpartition names are not unique

Also, moved some of the code out of handler.h and into partition specific files for better 
separation.
Also, moved some of the C funcs into partition_info as formal C++ methods

  using the new members of partition_info
sql/handler.h:
  moved this code into sql_partition.h
sql/mysql_priv.h:
  including sql_partition.h also now

  using the new members of partition_info
sql/sql_partition.cc:
  moved some of the functions out and into the partition_info class
  using the new members of partition_info
sql/sql_show.cc:
  using the new members of partition_info
win/cmakefiles/sql:
  added partition_info.cpp to the sql cmake file
sql/partition_element.h:
  New BitKeeper file ``sql/partition_element.h''
