Changing the default of libmysqlclient : it's now NO reconnection.

All our programs which use mysql_real_connect() and mysql_connect() are updated accordingly, though I have deliberately
made mysqlimport not reconnect anymore (already true for mysqldump >= 4.1.8).
All Connector devs have been warned about the change I'm doing here - which was agreed with Monty,
and fixes BUG#2555.

client/mysqlimport.c:
  explicit mention of NO reconnect (behaviour change). As most time is passed in LOAD DATA INFILE,
  and as it does not make sense to reconnect after a partly failed LOAD... And as mysqlimport sometimes
  does LOCK TABLES where we mustn't reconnect...

  Normally we should not reconnect (it's not good to have silent reconnection in the middle of a test),
  but 5.0 is too touchy to change it now. I'm marking it TODO.
