STABILITY FIX:
Fixed double free'd pointer bug in mysql_change_user() handling, that
enabled a specially hacked version of MySQL client to crash mysqld.
Note, that one needs to login to the server by using a valid user
account to be able to exploit this bug.
- Also split the package into client and a server sub-package which
depends on the client portion. This allows for adding/removing the server
without needing to remove ports that might be dependent on the client
portion.
- innodb FLAVOR goes away and is replaced with the max FLAVOR like the
real MySQL distribution which gives us both Berkeley DB and InnoDB tables
for transaction support.
