In file_loadraw() print the name of the file as well as its size
so that we know what file is being loaded and how big the file
is once complete. This has ELF modules and disk images emit the
same output.
Various fixes to hptrr(4):
- Use the existing vbus locks instead of Giant for the CAM sim lock.
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler MPSAFE.
- Don't attempt to pass data in the softc from probe() to attach().
- Remove compat shims for FreeBSD versions older than 8.0.

- Use the per-instance device lock instead of Giant for the CAM sim lock.
- Add global locks to protect the adapter list and DPC queues.
- Use wakeup() and mtx_sleep() to wait for certain events like the
  controller going idle rather than polling via timeouts passed to
  tsleep().
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler MPSAFE.

in terms of unload() This allows unloading all files by the loader
itself.
