4a676571e3 stand: Pass in the proper size for bootinfo
Missed one sizeof(bi) -> sizeof(*bi) in 9758dd3de1 conversion to
allocating bootinfo.

9758dd3de1 stand: Allocate bootinfo rather than have it be static
This saves 80 bytes (the new bootinfo structure was 84 bytes, and a
pointer is 4 bytes). The bi_load32 code is the same size.

d43bcf62a2 stand: Stop support booting 4.x and earlier kernels
FreeBSD 4.x and earlier used the bi_bios_geom to get the geometry of the
device. Starting in 5.x, with the wdc -> ata rewrite, it was used only
in pc98 kernels to report geometry of the drives. It can be safely
removed as booting kernels this old is no longer supported. This saves
176 bytes in the BIOS loader.

e895ab3fbd stand: Remove dead store to bi_kernelname
We set this value twice: once to 0 and once to the VA that has the name
of the kernel. The first store is redundant. In addition, these two
stores of 0 are also redundant. Since we never set them, they will
always be zero, even if we're called multiple times. This saves 21
bytes on BIOS loader.

fc352701ff stand: collapse all copies of *copyenv into md_copyenv
Use the efi's bi_copyenv to md_copyenv and place it in modinfo.c. Remove
all other nearly identical and efi's has the best error handling.

5d1531d9d4 stand: Move md_copymodules into modinfo.c and reduce copies
md_copymodules, bi_copymdoules, bi_copymodules32 (x2) and
bi_copymodules64 (x2) are all the same routine... Replace them all with
md_copymodules. This saves about 800 bytes on i386 BIOS loader, which is
a nice bonus.

bca9c87b61 stand: Create common/modinfo.h
Move all the MOD_xxx macros to this header. Each user of this interface
is currently required to define MOD_ALIGNMENT(l). modinfo was selected
because it sits inbetween modules and metadata and will make it easier
to migrate to new, shared intefaces.

a705c72f21 stand: use archsw.arch_copyin instead of i386_copyin
Since archsw.arch_copyin is always i386_copyin, this will be a nop in
terms of functionality. This is a diff reduction against other copies of
the code that differ only by what copyin routine they call.

3630506b9d loader: implement framebuffer console
Draw console on efi.
Add vbe framebuffer for BIOS loader (vbe off, vbe on, vbe list,
vbe set xxx).
autoload font (/boot/fonts) based on resolution and font size.
Add command loadfont (set font by file) and
variable screen.font (set font by size). Pass loaded font to kernel.

Export variables:
screen.height
screen.width
screen.depth

Add gfx primitives to draw the screen and put png image on the screen.
Rework menu draw to iterate list of consoles to enamble device specific
output.

Probably something else I forgot...

cdff10360e loader: create separate lists for fd, cd and hd, merge bioscd with biosdisk
Create unified block IO implementation in BIOS version, like it is done in UEFI
side. Implement fd, disk and cd device lists, this will split floppy devices
from disks and will allow us to have consistent, predictable device naming
(modulo BIOS issues).

c1418270b2 Extend loader(8) geli support to all architectures and all disk-like devices.
This moves the bulk of the geli support from lib386/biosdisk.c into a new
geli/gelidev.c which implements a devsw-type device whose dv_strategy()
function handles geli decryption. Support for all arches comes from moving
the taste-and-attach code to the devopen() function in libsa.

After opening any DEVT_DISK device, devopen() calls the new function
geli_probe_and_attach(), which will "attach" the geli code to the open_file
struct by creating a geli_devdesc instance to replace the disk_devdesc
instance in the open_file. That routes all IO for the device through the
geli code.

A new public geli_add_key() function is added, to allow arch/vendor-specific
code to add keys obtained from custom hardware or other sources.

With these changes, geli support will be compiled into all variations of
loader(8) on all arches because the default is WITH_LOADER_GELI.

de04d704a9 Use the actual struct devdesc at the start of all *_devdesc structs
The current system is fragile and requires very careful layout of all
*_devdesc structures. It also makes it hard to change the base
devdesc. Take a page from CAM and put the 'header' in all the derived
classes and adjust the code to match.

For OFW, move the iHandle h_handle out of a slot conflicting with
d_opendata. Due to quirks in the alignment rules, this worked.
However changing the code to use d_opendata storage now that it's a
pointer is hard, so just have a separate field for it.

All other cleanups were to make the *_devdesc structures match where
they'd taken some liberties that were none-the-less compatible enough
to work.
