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.

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.

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.

To further reduce the differences between the different MOD_xxx macros,
use MOD_ALIGN to do the proper alignment for the given use.

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.

devformat produces the same output as i386_fmtdev, so just use it to
reduce on the dependencies.

All callers of bi_load64 pass 0 as the addr parameter, so just remove
it and always calculate the last load address from the module chain.
No functional change.

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...

As a new x86 CPU vendor, Chengdu Haiguang IC Design Co., Ltd (Hygon)
is a joint venture between AMD and Haiguang Information Technology Co.,
Ltd., aims at providing x86 processors for China server market.
The first generation Hygon processor(Dhyana) shares most architecture
with AMD's family 17h, but with different CPU vendor ID("HygonGenuine")
and PCI vendor ID(0x1d94) and family series number 18h(Hygon negotiated
with AMD to confirm that only Hygon use family 18h).
To enable Hygon Dhyana support in FreeBSD, add new definitions
HYGON_VENDOR_ID("HygonGenuine") and X86_VENDOR_HYGON(0x1d94) to identify
Hygon Dhyana CPU.
Initialize the CPU features(topology, local APIC ext, MSI, TSC, hwpstate,
MCA, DEBUG_CTL, etc) for amd64 and i386 mode by sharing the code path of
AMD family 17h.
The changes have been applied on FreeBSD 13.0-CURRENT and tested
successfully on Hygon Dhyana processor.

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.
