jhb 5ac3853a0d Mark cd9660 MPSAFE and add support for using shared vnode locks during 
pathname lookups.
- Remove 'i_offset' and 'i_ino' from the ISO node structure and replace
  them with local variables in the lookup routine instead.
- Cache a copy of 'i_diroff' for use during a lookup in a local variable.
- Save a copy of the found directory entry in a malloc'd buffer after a
  successfull lookup before getting the vnode.  This allows us to release
  the buffer holding the directory block before calling vget() which
  otherwise resulted in a LOR between "bufwait" and the vnode lock.
- Use an inlined version of vn_vget_ino() to handle races with ..
  lookups.  I had to inline the code here since cd9660 uses an internal
  vget routine to save a disk I/O that would otherwise re-read the
  directory block.
- Honor the requested locking flags during lookups to allow for shared
  locking.
- Honor the requested locking flags passed to VFS_ROOT() and VFS_VGET()
  similar to UFS.
- Don't make every ISO 9660 vnode hold a reference on the vnode of the
  underlying device vnode of the mountpoint.  The mountpoint already
  holds a suitable reference.
