merge mysql.initial.sql and mysql5.initial.sql

[tensor]

There are conditional comments in MySQL dialect of SQL. Something like this:

CREATE /*!32302 TEMPORARY */ TABLE t (a INT);

Using these it is possible to merge the two files into one.

See http://dev.mysql.com/doc/refman/4.1/en/comments.html

I think we should require mysql 5.x as we do with php.
