fb74e5f595 Add splitfs vfs layer into libstand, which allows loading big kernels and
modules split across several physical medias. Following is how it works:

The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.

	foo.aa "Kernel floppy 1"
	foo.ab "Kernel floppy 2"
	foo.ac "Kernel and modules floppy"

For each file segment, the process is:

- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located

RE team is free to use this feature in the upcoming 5.0-DP1.

kernels, modulo the PR kern/17422.)

870fb18bc1 Oops, the previous revision (1.35) broke booting from floppies
because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.

Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).

83f4b92050 Unrevert revision 1.12. Revision 1.14 backed this out saying it was
backing out the 1024 sector boot0, but revision 1.12 had nothing to do with
that.  Instead, it documented various compile time options for boot0 and
allowed them to be overridden via make.conf or options on the make
command line.

0889b9be41 - Add 'fwrite' and 'fseek' words for writing to and seeking on files.
- Change the 'fopen' keyword to accept a mode parameter.  Note that this
  will break existing 4th scripts that use fopen.  Thus, the loader
  version has been bumped and loader.4th has been changed to check for a
  sufficient version on i386 and alpha.  Be sure that you either do a full
  world build or install or full build and install of sys/boot after this
  since loader.old won't work with the new 4th files and vice versa.

28703190c5 Add new boot flag to i386 boot: -p.
This flag adds a pausing utility. When ran with -p, during the kernel
probing phase, the kernel will pause after each line of output.
This pausing can be ended with the '.' key, and is automatically
suspended when entering ddb.

This flag comes in handy at systems without a serial port that either hang
during booting or reser.

5af9115c77 This is a new CD bootstrap utility designed to replace cdldr. According
to the El Torito standard for CD booting, a CD may boot in "No emulation"
mode without using a floppy image.  In this mode, the BIOS loads a program
off of the CD into memory and creates a BIOS device using 2048 byte sectors
for the CD.  According to the standard, this program can be up to 0xFFFF
virtual (512-byte) sectors long.  The old cdldr depended on this by having
the BIOS load the entire loader and the small cdldr stub as one binary
similar to pxeboot so that cdldr didn't have to read the CD to find the
loader.  However, the NT no emulation loader just uses 1 disk sector
(4 virtual sectors), so it seems that at least some BIOS writers just did
enough to get NT to boot by only loading 1 sector and ignoring the sector
count.  Thus, while cdldr should have worked in theory, it doesn't in
practice.  This replacment fits entirely in 1 sector and includes simple
ISO 9660 support.  It looks for /boot/loader on the CD and loads it up
using the BIOS.  This allows us to not have to depend on the limited size
of floppy images but use a full GENERIC kernel for CD-ROM installs in the
future, among other things.

This version of cdboot is a bit bloated as it includes some useful
debugging routines that people can pull to use in other x86 assembly
modules.  Even with all the debugging cruft, we still have 272 bytes to
spare.

ce4c60d38d Fix the ILLEGAL fdisk table that is there for supporting "dangerously
dedicated" mode.  This was specifying that there are 256 (illegal!)
heads on the disk.  If bioses store that in a byte, and it gets truncated
to 0, then that almost certainly causes the infamous divide-by-zero
nightmare.

This is also most likely the reason why the Thinkpad T20/A20 series
were locking up when FreeBSD was installed.  This is also the most likely
reason why a boot1 being present causes an IA64 box to lock up at boot.
(removing the "part4" stuff from boot1.s fixes the IA64 boxes and would
most likely have fixed the T20/A20 and some TP600E series thinkpads)

0f2c85b335 Add support for loading bzip2-compressed kernels and modules. This support
is turned off by default and could be enabled by defining LOADER_BZIP2_SUPPORT
make variable. Also make gzip support optional (turned on by default) -
it could be turned off via LOADER_NO_GZIP_SUPPORT make variable.

Please note, that due to limit on the amount of memory available to the
loader(8), it is possible to load modules/kernels compressed with the smallest
block size supported by the bzip2 - 100k (`-1' bzip2(1) option), however
even in this mode bzip2(1) usually provides better compression ratio than
gzip(1) in its best compression mode.
