Extended SELECT INTO OUTFILE/DUMPFILE

Percona Server for MySQL extends the SELECT INTO ... OUTFILE and SELECT INTO DUMPFILE commands to add support for UNIX sockets and named pipes. Before this was implemented the database would return an error for such files.

This feature allows using LOAD DATA LOCAL INFILE in combination with SELECT INTO OUTFILE to quickly load multiple partitions across the network or in other setups, without having to use an intermediate file that wastes space and I/O.
