usbdump stores data. Until this patch it was not possible
to exchange traces between 32-bit, 64-bit, big- and
little endian platforms. The problem is the dynamic nature
of the BPF timestamp in the header. All other fields are
fixed size and little endian.

- Add more fields for USB device and host mode
- Add more information to USB PF header so that decoding
can easily be done by software analyzer tools like
Wireshark.
- Optimise usbdump to display USB streams in text format
more efficiently.
- Software using USB PF must be recompiled after
this commit, due to structure changes.

- Remove reference to sprintf. Use printf directly. This part of
the code should be optimised further to avoid many small printouts.
Setting a sensible line buffer length could help aswell when printing
out megabytes of data per second.

confused with USB OUT or USB IN packets though it just represents USB
submit or done. To know the USB packet direction, the endpoint address
should be referred.
