Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Revert previous commit and add myself to the list of people who should
know better than to commit with a cat in the area.

Add necessary include.

Move the new USB stack into its new home.
