Fix usage of mysqld option --new, --old, --safe and --skip_new to not disable things that are proven stable or enable things that are not usefull.
sql/field.cc:
Remove feature of 'new_mode' that was never implemtented in a newer MySQL version.
sql/item_cmpfunc.cc:
Boyer more is stable; Don't have to be protected by --skip-new anymore
sql/mysqld.cc:
Don't disable some proven stable functions with --skip-new
sql/records.cc:
Don't disable record caching with --safe-mode anymore
sql/sql_delete.cc:
Do fast truncate even if --skip-new or --safe is used
sql/sql_parse.cc:
Use always mysql_optimizer() for optimizer (instead of mysql_recreate_table() in case of --safe or --skip-new)
sql/sql_select.cc:
Don't disable 'only_eq_ref_tables' if --safe is used.
sql/sql_yacc.yy:
Removed not meaningfull test of --old
