8b612c4b4a This commit is the embodiment of some VFS read clustering improvements.
Firstly, now our read-ahead clustering is on a file descriptor basis and not
on a per-vnode basis.  This will allow multiple processes reading the
same file to take advantage of read-ahead clustering.  Secondly, there
previously was a problem with large reads still using the ramp-up
algorithm.  Of course, that was bogus, and now we read the entire
"chunk" off of the disk in one operation.   The read-ahead clustering
algorithm should use less CPU than the previous also (I hope :-)).

NOTE:  THAT LKMS MUST BE REBUILT!!!

10dd32cd87 Added prototypes.
cd9660_rrip.c:
Added lots of bogus casts to hide type errors exposed by the prototypes.
(Different structs are assumed to have a common prefix.)

cd9660_vnops.c:
Finished staticizing.

2d6ec99c0a Since FreeBSD clustering code now supports filesystems < PAGE_SIZE,
enable clustering for cd9660, thereby giving a BIG performance boost.

ba14c32725 Fix isoilk hang caused by not checking for read-onlyness in several places.
The fix for this in Lite-2 is more complete, but these quick hacks of mine
are safer for now. I plan to integrate the additional Lite-2 stuff at some
later time. Should completely fix PR810.

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

1b9d1a091a Readdir on a CDrom would return bogus "d_type" values, potentially confusing
everybody (incl find(1) ?).  Initialize it to DT_UNKNOWN.  Maybe we can
do better, but I don't have the time.

4a565df5ed strategy for block and char devices are rightfully spec_strategy.
I feel like yanking all the "ISODEVMAP" stuff altogether, it looks
like a bad kludge...

988fa8efe3 Roll in my changes to make the cd9660 code understand the older
(original "High Sierra") CD format.  I've already implemented this for
1.1.5.1 (and posted to -hackers), but didn't get any response to it.
Perhaps i'm the only one who has such an old CD lying around...

Everything is done empirically, but i had three of them around (from
different vendors), so there's a high probability that i've got it
right. :)

- Make a number of filesystems work again when they are statically compiled
  (blush)

- FIFOs are no longer optional; ``options FIFO'' removed from distributed

1dbaf90cdb Obtained from:
Remove the unnecessary inclusion of disklabel.h in cd9660_vfsops.c so
that I don't have to worry about the latter when changing disklabel.h.

Supply prototypes for some functions that were implicitly declared and
fix the resulting warnings and errors (timevals were punned to timespecs).

06e79831b1 Fixed some confusion between the size of a logical block and the size of a
device block which was stopping symbolic links working.

cd9660_readdir was incorrectly casting a pointer to the d_namlen field of a
struct dirent to a (u_short*) which caused the directory entries "." and ".."
to read incorrectly.
