Two threads send_traverse_thread() and receive_writer_thread() should
end with thread_exit();

Mostly a cosmetic issue under IllumOS.

UFS2 extended attribute names are not NUL-terminated.  Handle
appropriately.

Correct the EXTATTR_BASE_LENGTH() macro, which handled ea_namelength ==
one (mod eight) extended attributes incorrectly.

The ea_name string is not nul-terminated.  Correct the documentation.

Because the subsequent field is padded to 8 bytes, and the padding is
zeroed, the ea_name string will appear to be nul-terminated whenever the
length isn't exactly one (mod eight).

This was introduced in r167010 (2007).

Additionally, mark the length fields as unsigned.  This particularly
matters for the single byte ea_namelength field, which can represent
extended attribute names up to 255 bytes long.

No functional change.
