c679ae39a8 biosdisk.c 
Implement a new variable 'root_disk_unit' which supersedes
	'num_ide_disks' and makes it possible to explicitly set the
	root device unit number regardless of type considerations.

bootinfo.c
	If we can't calculate a dev_t for the root disk, complain and
	don't proceed to boot with an invalid boot device.

5d3d992565 Fill in the bi_bios_dev field in the bootinfo struct; the loader doesn't 
guess this value well in anything other than the simplest of situations.

d7478bf0df Push version numbers up to 1.00. This is just intended to reflect 
that the BTX code can be regarded as stable: there are no associated
code changes.

378972ac6b Transition from using Perl to using awk for our text-manipulation 
needs.  This removes the dependancy on Perl for the generation of the
loader, allowing the world to be built on a perl-free system.

ba536e2ae8 Preserve the previous loader as loader.old. 
Note no matching commit for the Alpha, as the alpha boot0 stage does
not have the ability to prompt for user input.

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.

cf9443f92b Add simple terminal emulator, compatible with cons25. Currently supported 
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.

af1f6e0673 Implement a simple LRU block cache. By default this is initialised to 16k, 
and will bypass transfers for more than 8k.  Blocks are invalidated after
2 seconds, so removable media should not confuse the cache.

The 8k threshold is a compromise; all UFS transfers performed by
libstand are 8k or less, so large file reads thrash the cache.
However many filesystem metadata operations are also performed using
8k blocks, so using a lower threshold gives poor performance.

Those of you with an eye for cache algorithms are welcome to tell me
how badly this one sucks; you can start with the 'bcachestats' command
which will print the contents of the cache and access statistics.

dc8be6a8f5 - Add a new command 'lsdev' to list devices which might be likely to host 
filesystems.
 - New 'help' command and data in the help.* files (not yet installed),
   provides topic and subtopic help, indexes, etc.
 - Don't crash if the user tries to set an invalid console.  Be helpful
   instead.
 - Expand tabs (badly) on the i386 video console.
 - Some minor cosmetic changes.
