Implemented FIFO support in Downstream host, significant speed increase!

Browse Source 
Each USB transaction passed to the driver now consists of multiple
64-byte packets. 8 packets when receiving, 4 packets when transmitting.
The STM32 silicon bugs out when more than 4 packets are scheduled to
write at a time :(

Reads 1.0MB/sec, writes 967kB/sec, not CPU limited :)
