Log:
SVN rev 189502 on 2009-03-08 00:11:26Z by luigi
MFC rev.188571
Clarify and reimplement the bioq API so that bioq_disksort() has
the correct behaviour (sorting by distance from the current head position
in the scan direction) and bioq_insert_head() and bioq_insert_tail()
have a well defined (and useful) behaviour, especially when intermixed
with calls to bioq_disksort().
See the original commit log for more details.
NO API/ABI changes (except from fixing bugs and defining
unspecified behaviour that no code should rely on).
