3d8993c197 Modify the boot loader to recognize the -C flag and pass the RB_CDROM 
flag to the kernel to mount a CDROM as the root filesystem.  Alternatively,
the boot_cdrom env var can be set.

As Mike Smith noted, "-C is the "wrong" way to do this", but this is
an acceptable stopgap in lieu of a better way.

c03b24b2d8 Damn, I thought I had committed this already, but it seems not. 
Move the relocated boot1 and arg transfer space from 0x600/0x800 to
0x700/0x900.  In theory this should make no difference, apart from the fact
that Buslogic controllers happen to use a few bytes at 0x600 for some sort
of scratch space for it's int 0x13 hook (!!!), causing the machine to crash
badly when the boot2 code makes it's callbacks into boot1 for disk IO.

capabilities are: AF, AB, cm, ho, me, cd. The code is hidden behind
-DTERM_EMU - should it cause any problems, you can remove this define
to get back the old behaviour.

You'll find some examples how to use it in src/share/examples/bootforth.
