mariadb, percona: descriptions are identical to mysql ports'

[ryandesign (Ryan Carsten Schmidt)]

The descriptions of all the MySQL ports are identical:

$ port info --name --long_description mysql4 mysql5{,1,5,6} mariadb percona
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql4
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql5
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql51
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql55
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql56
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mariadb
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: percona

That's not awful, except that I expected the description of mariadb to say "MariaDB is..." and for percona to say "Percona is...", and perhaps have a mention of being forks of MySQL.

In all these ports, the mention of mSQL is perhaps archaic. By now, nobody's confused about what MySQL is.
