Implemented FIFO support in Downstream host, significant speed increase!
...
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 :)

Fixed enumeration issues with low-speed devices:
...
- Unexpected second port-connected interrupt on cold boot with low-speed
device connected.
- Retry on failure to get device descriptor. (We still fail after three
attempts, but that is better than failing after the first one!)
Also changed eclipse project to use external builder.

Refactor a bunch of stuff in Upstream project to avoid endless confusion
...
with Downstream project.
Also fixed a couple of things in upstream_spi.c and
upstream_interface_msc.c but due to file rename the diff is not
obvious...
