of an error in option handling. This can sometimes be useful in
scripts.

Changed some exit code names and corresponding numbers.

Fixed a bug in mysqld.cc, in replication related options.

Added a global flag in my_getopt, which can be set by any program
that is using my_getopt, which tells whether the client should
print the error message itself, or whether my_getopt should do it.
The default is that my_getopt will print the error messages.
