On RISC-V, Clang warns with:
cast to smaller integer type 'unsigned int' from 'void (*)(void *)'
Instead, use %p as the standard format specifier for printing pointers.
Whilst Arm's pointer size is the same as unsigned, it's still cleaner to
use the right thing there too.

This implementation doesn't have any major deviations from the other EFI
ports. I've copied the boilerplate from arm and arm64.
I've tested this with the following boot flows:
OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD
OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD
Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required,
as the HSM extension is needed to bring them up explicitly. Because of this,
using BBL as the SBI implementation will not be possible. Additionally, there
are a few recent u-boot changes that are required as well, all of which will be
present in the upcoming v2020.07 release.

The zfs reader development did reach to the point where linking boot1,
we will get errors about duplicate symbols Malloc, Free, Calloc.
We can just use libsa version, just as loader.efi does. The only concern is,
libsa zalloc is using fixed size heap region, I did pick 64MB as other
stage instances are using, but this size is likely not optimal. In any case,
with limited memory setups, we should boot loader.efi directly.

These are picked out by the amd64-gcc6 build; time() is declared in <time.h>
and delay() is declared in <bootstrap.h>. These are the correct places for
these in stand/, so remove the duplicate declarations and make sure the
delay() consumer in libefi that depended on the extra delay() declaration
includes <bootstrap.h>.

We should have nextboot feature implemented in libsa zfs code.
To get there, I have created zfs_nextboot() implementation based on
two sources, our current simple textual string based approach with added
structured boot label PAD structure from OpenZFS.
Secondly, all nvlist details are moved to separate source file and
restructured a bit. This is done to provide base support to add nvlist
add/update feature in followup updates.
And finally, the zfsboot/gptzfsboot disk access functions are swapped to use
libi386 and libsa.

On some UEFI implementations the ConsOut EFI variable is not a device
path end type so we never move to the next node. Fix this by always
incrementing the device path node pointer, with a sanity check that
the node length is large enough so no two nodes overlap.
While here return failure on malloc failure rather than a NULL pointer
dereference.

The u-boot EFI implementation of the ReadBlocks and WriteBlocks methods
requires that the provided buffer meet the IO alignment requirements of
the underlying disk. Unlike loader.efi, gptboot.efi doesn't check this
requirement, and therefore fails to perform a successful read. Adjust
secbuf's alignment to 4K in hopes that we will always meet this
requirement.

The efi console init is avoided since conin setup was moved to probe.
In case the console is re-initialized, we need to pick up colors
from environment.
we have crc32(const void *, size_t) in libsa. Unfortunately zlib has
crc32(long, const unigned char *, unsigned) and we have conflict.
Since we do build libsa with zlib, we can use zlib version instead.

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.
For doing an install via loader, avoiding the need to rewind
large files is critical.
This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

smbios used to be an i386 only kinda weird quirk to the x86

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.

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.

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).
