Changed the default location of the log output to LOG_FILE,
for backward compatibility with MySQL 5.0

  
On the windows platform, if an instance object failed to initialize during
program start, the instance manager would crash.
This could happen if an incorrect mysqld path was supplied in the 
defaults configuration file.
The patch prevents the program from crashing and makes it show an
error message instead.

The Item_date_typecast::val_int function doesn't reset null_value flag.
This makes all values that follows the first null value to be treated as nulls
and led to a wrong result.

Now the Item_date_typecast::val_int function correctly sets the null_value flag
for both null and non-null values.

a temporary table.

The result string of the Item_func_group_concat wasn't initialized in the 
copying constructor of the Item_func_group_concat class. This led to a
wrong charset of GROUP_CONCAT result when the select employs a temporary
table.

The copying constructor of the Item_func_group_concat class now correctly
initializes the charset of the result string.
