smbios used to be an i386 only kinda weird quirk to the x86
architecture. But UEFI picked it up, dusted it off and now it's many
other locations. Make it base technology by moving it to libsa and
fixing up the compliation. The code has issues with unaligned access
still, but that will be addressed in a followup commit.

Create a ptov() function. It's basically the same as the btx PTOV
macro, but works everywhere. smbios needs this to translate addresses,
but the translation differs between BIOS booting and EFI booting. Make
it a function so one smbios.o can be used everywhere. Provide
definitions for it in the two loaders affected.

We still need to set the hooks to prevent improper manipulations thereafter
at the loader prompt, but as it is we're actively preventing loaddev from
being set correctly in some circumstances (ZFS in particular) and doing more
work than needed with currdev -- that hook in particular validates it as a
correct device, which we can assume isn't needed in this context.

From UEFI specification 2.8, page 434:
"It should also be noted that certain input devices may not be able to produce
shift or toggle state information, and in those cases the high order bit in
the respective Toggle and Shift state fields should not be active."
But we still need to check for ScanCode and UnicodeChar.

Just as disks can have nested partitions, the same happens with cd devices,
so we need to detect device paths and make sure we will not mix the handles.
To address this:
we fetch handle array and create linked list of block devices.
we walk the list and detect parent devices and set children pd_parent.
for {fd, cd, hd}, we walk device list and pick up our devices and store to
corresponding list. We make sure we store parent device first.
For sorting we use 3 steps: We check for floppy, we check for cd and then
everything else must be hd.
In general, it seems the floppy devices have no parent.
CD can have both parents and children (multiple boot entries, partitions
from the hybrid disk image).

RB_MULTIPLE without RB_SERIAL set is valid, and means 'Video first, then serial'
to the kernel (so kernel messages go to both, but /etc/rc uses video console
(this should be fixed, btw, but another day)). Check for RB_MULTIPLE as well as
RB_SERIAL where we want to to serial things. This means we'll use the old code
for emulation in these situations, which is likely best since we're outputing to
both and the old code is ligher weight allowing both to keep up w/o weird
scrolling things.
With a very large kernel or module the staging area may be too small to
hold it. When this is the case try to allocate more space before failing
in the efi copyin/copyout/readin functions.

In the EFI implementation in U-Boot no ConOut efi variable is created,
this cause loader to fallback to TERM_EMU implementation which is very
very very slow (and uses the ConOut device in the system table anyway).
The UEFI spec aren't clear as if this variable needs to exists or not.

In case of efi console having serial backend (video + serial or only serial),
we need to stick with old emulator till we can draw console.
Eventually we would need to get console terminal emulator to be removed
from serial console because the serial link already has the terminal.
However, we need to implement comconsole on all efi platforms first, then
we need the ability to draw console, so we do not have to use SimpleTextOutput
protocol (which will write both on video and serial in case of multiplexed
ComOut).

Since local UEFI console is implemented on top of framebuffer,

Simple Text Mode to do the scroll for us.
Add settable variables to control teken default color attributes.
The supported colors are 0-7 or basic color names:
black, red, green, brown, blue, magenta, cyan, white.
The current implementation does add some duplication which will be addressed
later.
UEFI specification 2.7A, EFI_BLOCK_IO_PROTOCOL, page 566.
The ioalign property does define the alignment of data buffer.
If the alignment is required and our buffer is not aligned, or if
the data buffer is not multiple of Blocksize, we need to use bounce buffer
to perform the block IO. This is much like with BIOS version, except
there the INT13 needs buffer to be located in low memory.
Additionally, we need to handle disk writes properly.
Replace mini cons25 emulator with teken, this does enable us proper console
terminal for loader and will make it possible to implement different
back end callbacks to draw to screen.
At this time we still only "draw" in text mode.
The cd handles should be collected as list of partitions. Some systems also
provide base name for block device (like PciRoot(0x0)/Pci(0x5,0x0)), we need
to be careful about those.
To make out life a bit easier, we prepare not just an array of handles, but we
allocate pdinfo struct for each handle and devicepath, then we can simplify
our work to sort the devices.

The HandleProtocol() is deprecated interface and we should use OpenProtocol()
