[BusyBox] Ahem: Bwahahahahahahahaha!

Here's the bzip compression side source code, bzipped with itself. :)

Do not expose to direct sunlight.  Caution, severe tire damage.  Offer not 
applicable during total eclipse of the sun.  Void where prohibited by large 
men with sharp knives.  You with your own copy of the board game "Risk".

It worked for me.  Anybody trusting their data to this thing just yet is an 
even bigger fool than I am, and I've got the cap with bells on and 
everything.  (Well I used to write for The Motley...  nevermind.)

There are 8 gazillion badly commented out printfs in this thing, all of which 
can be removed because they're debug stuff.  I'm still debugging.  The 
huffman coding tables I'm generating work, but apparently aren't quite 
optimal (the bzip archives this creates are about 0.01% bigger than jseward's 
verion, I could just parrot his code but I want to understand WHY, and 
comment it).

After a refractory period, I'll clean up crap.c (the block sorting code, which 
is currently copied verbatim from the original, asserts and all).

It compiles to 13392 bytes, -Os and stripped.  And over 6k of that is the 
block sorting code, so there's still plenty of room to shrink...

The first half of the cleanup has been done (modulo some mopping up like 
removing the "//fprintf(stderr,blah);" lines).  On to phase 2...

I'll stop now.
