Make the data returned by devinfo harder to overflow.

Rather than using fixed-length strings, pack them into a string table
to return. Also expand the buffer from ~300 charaters to 3k. This should
be enough, even for USB.

This fixes a problem where USB pnp info is truncated on return to
userland.
