Make handler::{write,delete,update}_row private. It's critical

that the entire server uses their public ha_* counterparts instead,
since only then we can ensure proper tracing of these calls that
is necessary for Bug#12713.
A pre-requisite for Bug#12713 "Error in a stored function called from 
a SELECT doesn't cause ROLLBACK of statem"


sql/ha_partition.cc:
  Use ha_write_row, ha_update_row, ha_delete_row instead of now-private
  write_row, update_row, delete_row. 
  In future ha_* calls will contain more than just a call to the binary
  log, so it's essential they are used consistently everywhere in the server.
  
  Disable the undesired effect of double binary logging of changes
  to partitioned tables with tmp_disable_binlog.
sql/handler.h:
  Make write_row, update_row, delete_row private. It's critical
  that the entire code base uses ha_write_row, ha_update_row, ha_delete_row
  instead -- in future, ha_* counterparts will have more common
  functionality than just a call to the binary log.
sql/sql_select.cc:
  Use ha_write_row, ha_update_row, ha_delete_row instead of
  write_row, update_row, delete_row respectively. 
  The change affects the join execution code that works with an
  intermediate internal temporary table. Do not disable binary logging,
  since it's unnecessary - temporary tables are not replicated
  by row level replication.
sql/sql_table.cc:
  Use ha_write_row in copy_data_between_tables - the function
  that writes data from the original table to a temporary copy
  when executing ALTER TABLE. Do not disable binary logging
  since temporary tables are not replicated by row level 
  replication anyway.
