duplication in error messages; in particular, there are a few cases
where error messages get copied from one archive object to another

Restoring POSIX.1e Extended Attributes on FreeBSD, part 1
This implements the basic ability to restore extended attributes
on FreeBSD, including a test suite.
Zip entries that are zero length but stored with deflate. This
is arguably a silly thing to do (deflating a zero-length file actually
makes it bigger) but apparently quite a few Zip writers do this.
This was broken in two places: archive_write_disk disliked being asked
to write data to zero-length files (even if the write was zero-length)
and zip_read_file_header tripped over itself when non-regular files
had compressed bodies.
from libarchive.googlecode.com: Add a new "archive_read_disk" API
that provides the important service of reading metadata from the
disk. In particular, this will make it possible to remove all
knowledge of extended attributes, ACLs, etc, from clients such
as bsdtar and bsdcpio.
Closely related, this API also provides pluggable uid->uname
and gid->gname lookup and caching services similar to
the uname->uid and gname->gid services provided by archive_write_disk.
Remember this is also required for correct ACL management.
Documentation is still pending...
ABIs:
- Store the FPU initial control word in the pcb for each thread.
- When first using the FPU, load the initial control word after restoring
the clean state if it is not the standard control word.
- Provide a correct control word for Linux/i386 binaries under
FreeBSD/amd64.
- Adjust the control word returned for fpugetregs()/npxgetregs() when a
thread hasn't used the FPU yet to reflect the real initial control
word for the current ABI.
- The Linux/i386 ABI for FreeBSD/i386 now properly sets the right control
word instead of trashing whatever the current state of the FPU is.

anyway. The console probe will still fail unless a VGA adapter is found.

- Remove the control word parameter to npxinit(). It was always set
to __INITIAL_NPXCW__.
- Remove npx_cleanstate_ready as the cleanstate is always initalized
when it is used.
- Improve the handling of the case when the FPU isn't present. Now
the npx0 device no longer succeeds in its probe so all of npx_attach()
is skipped. Also, we allow this case with SMP (though that shouldn't
actually occur as all i386 systems that support SMP have FPUs) now.
SMP was only an issue back when we had an FPU emulator which was not
per-CPU.
- MFamd64: Clear some of the state in npx_cleanstate rather than leaving
it as garbage.
- MFamd64: When a user thread first uses the FPU, use npx_cleanstate for
the initial FPU state.

- fpudna() always returned 1 since amd64 CPUs always have FPUs. Change
the function to return void and adjust the calling code in trap() to
assume the return 1 case is the only case.
- Remove fpu_cleanstate_ready as it is always true when it is tested.
Also, only initialize fpu_cleanstate when fpuinit() is called on the BSP.
