Subject: [PATCH 3/3] lib/DBD/File.pm: fix CVE-2014-10401

Dig into the root cause of RT#99508 - which resulted in CVE-2014-10401 - and
figure out that DBI->parse_dsn is the wrong helper to parse our attributes in
DSN, since in DBD::dr::connect only the "dbname" remains from DSN which causes
parse_dsn to bailout.

Parsing on our own similar to parse_dsn shows the way out.
