Some *very* major changes by darrenk@insightdist.com (Darren King)

Browse Source 
==========================================
What follows is a set of diffs that cleans up the usage of BLCKSZ.

As a side effect, the person compiling the code can change the
value of BLCKSZ _at_their_own_risk_.  By that, I mean that I've
tried it here at 4096 and 16384 with no ill-effects.  A value
of 4096 _shouldn't_ affect much as far as the kernel/file system
goes, but making it bigger than 8192 can have severe consequences
if you don't know what you're doing.  16394 worked for me, _BUT_
when I went to 32768 and did an initdb, the SCSI driver broke and
the partition that I was running under went to hell in a hand
basket. Had to reboot and do a good bit of fsck'ing to fix things up.

The patch can be safely applied though.  Just leave BLCKSZ = 8192
and everything is as before.  It basically only cleans up all of the
references to BLCKSZ in the code.

If this patch is applied, a comment in the config.h file though above
the BLCKSZ define with warning about monkeying around with it would
be a good idea.

(Also cleans up some of the #includes in files referencing BLCKSZ.)
