fix Ethernet header alignment problem on alpha and sparc64. Also change all
users of m_uiotombuf to pass proper offset.

access to POSIX Semaphores:
mac_init_posix_sem() Initialize label for POSIX semaphore
mac_create_posix_sem() Create POSIX semaphore
mac_destroy_posix_sem() Destroy POSIX semaphore
mac_check_posix_sem_destroy() Check whether semaphore may be destroyed
mac_check_posix_sem_getvalue() Check whether semaphore may be queried
mac_check_possix_sem_open() Check whether semaphore may be opened
mac_check_posix_sem_post() Check whether semaphore may be posted to
mac_check_posix_sem_unlink() Check whether semaphore may be unlinked
mac_check_posix_sem_wait() Check whether may wait on semaphore
Update Biba, MLS, Stub, and Test policies to implement these entry points.
For information flow policies, most semaphore operations are effectively
read/write.

- In vm_fault only acquire Giant if the underlying object has NEEDSGIANT

- In vm_object_shadow inherit the NEEDSGIANT flag from the backing object.
perfect solution as the lower vm object can change at unpredictable times
if our lower vp happens to be on another unionfs, etc.

- Add a sysctl for the number of items on the worklist.
- Use a more canonical loop restart in softdep_fsync_mountdev, it saves
some code at the expense of a goto and makes me worry less about
modifying a variable that should be private to the TAILQ_FOREACH_SAFE
macro.
devstat_end_transaction is called from a fast interrupt. Presently
there is no way for mtx_assert to determine that we're not executing
in a real thread context.
