Remove ODBCRouter support

Hi If no one objects, I intend to remove the old ODBCRouter support from ext/odbc, this has not had any releases for 8 years on Unix and I highly doubt anyone are still using that with PHP. I will commit a patch within the next few days for this. I had a look over all other Unix flavors we support with ODBC, and all of them had releases within the last few years so I consider them still supported. -- regards, Kalle Sommer Nielsen kalle@php.net
