Update the CAM API for FreeBSD 10:

Browse Source 
- Remove the timeout_ch field.  It's been deprecated since FreeBSD 7.0;
  MPSAFE drivers should be managing their own timeout storage.  The
  remaining non-MPSAFE drivers have been modified to also manage their own
  storage, and should be considered for updating to MPSAFE (or removal)
  during the FreeBSD 10.x lifecycle.

- Add fields related to soft timeouts and quality of service, to be used
  in upcoming work.

- Add room for more flags in the CCB header and path_inq structures.

- Begin support for extended 64-bit LUNs.

- Bump the CAM version number to 0x18, but add compat shims.  Tested with
  camcontrol and smartctl.
