writing data to the file system, if the "optimal" file system I/O
operation block size is less than TP_BSIZE, leave fssize alone (i.e.
at its default setting of MAXBSIZE). This was causing restore's
stack to be trashed, because the end-of-buffer checking/flushing code
around line 680 would never notice that the buffer was full (because
it'd be comparing a buffer segment index, which would always be >= 1, to
fssize / TP_BSIZE, which could be zero in that case), and would keep
filling and filling and filling...
drisavar.h pretends to provide a few bus.h macros, hardwired to
that chip.
This should eventually be replaced by attachment code for the normal
com.c driver, once that one is split up into chip core driver and
attachment code, and once we have busxxx macros in NetBSD/Amiga.

aout2bb transforms a.out files with reloc information into bootblock format
files with a compressed relocation info.
bbstart.s relocates the bootblock using this compressed info, before jumping
to C code.
txlt changes some more of the absolute references to pc-relative ones (we know
we have a single code + data address space).
If you ever try to change this: don't even dare to change the compiler options;
they were found in weeks of trial and error as the ones producing the smallest
(not necessarily fastests) code.
installboot is just a script around dd, for now.
Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added
by myself.

Also, the munging is extended by inserting an instruction that branches
past the header, so the same boot image can be used on all supported
sun platforms.
* Add :su#: entry for the RZ58, which uses ZBR and is larger than
multiplying out ns, nt, nc would suggest.
* Add some entries for locally-popular third-party disks, again
adding :su#: entries, as examples..
