  Preparation for table creation

  SYNOPSIS
    mysql_prepare_create_table()
      session                       Thread object.
      create_info               Create information (like MAX_ROWS).
      alter_info                List of columns and indexes to create
      tmp_table                 If a temporary table is to be created.
      db_options          INOUT Table options (like HA_OPTION_PACK_RECORD).
      file                      The Cursor for the new table.
      key_info_buffer     OUT   An array of KEY structs for the indexes.
      key_count           OUT   The number of elements in the array.
      select_field_count        The number of fields coming from a select table.

  DESCRIPTION
    Prepares the table and key structures for table creation.

  NOTES
    sets create_info->varchar if the table has a varchar

  RETURN VALUES
    false    OK
    true     error
