Fix warnings flagged by the new warning option -Wunused-but-set-variable that was added to GCC 4.6 and that is enabled by -Wunused and -Wall. The option causes a warning whenever a local variable is assigned to but is later unused. It also warns about meaningless pointer dereferences. client/mysql.cc: Meaningless pointer dereferences. client/mysql_upgrade.c: Check whether reading from the file succeeded. extra/comp_err.c: Unused. extra/yassl/src/yassl_imp.cpp: Skip instead of reading data that is discarded. include/my_pthread.h: Variable is only used in debug builds. include/mysys_err.h: Add new error messages. mysys/errors.c: Add new error message for permission related functions. mysys/mf_iocache.c: Variable is only checked under THREAD. mysys/my_copy.c: Raise a error if chmod or chown fails. mysys/my_redel.c: Raise a error if chmod or chown fails. regex/engine.c: Use a equivalent variable for the assert. server-tools/instance-manager/instance_options.cc: Unused. sql/field.cc: Unused. sql/item.cc: Unused. sql/log.cc: Do not ignore the return value of freopen: only set buffer if reopening succeeds. Adjust doxygen comment to the right function. Pass message lenght to log function. sql/mysqld.cc: Do not ignore the return value of freopen: only set buffer if reopening succeeds. sql/partition_info.cc: Unused. sql/slave.cc: No need to set pointer to the address of '\0'. sql/spatial.cc: Unused. Left for historical purposes. sql/sql_acl.cc: Unused. sql/sql_base.cc: Pointers are always set to the same variables. sql/sql_parse.cc: End statement if reading fails. Store the buffer after it has actually been updated. sql/sql_repl.cc: No need to set pointer to the address of '\0'. sql/sql_show.cc: Put variable under the same ifdef block. sql/udf_example.c: Set null pointer flag appropriately. storage/csv/ha_tina.cc: Meaningless dereferences. storage/example/ha_example.cc: Return the error since it's available. storage/myisam/mi_locking.c: Remove unused and dead code.
