d09b92b4d4 lualoader: Add a loaded hook for others to execute upon config load
This will not be executed on reload, though later work could allow for that.
It's intended/expected that later work won't generally need to happen on
every config load, just once (for, e.g., menu initialization) or just when
config is reloaded but not upon the initial load.

c4a58f8f99 Remove comments and assertions that are no longer valid after r330809.
r330809 replaced duplication of devdesc struct fields with an embedded copy
of the devdesc struct, to avoid fragility.  That means all the scattered
comments indicating that structs must match are no longer valid.  Likewise
asserts that attempted to mitigate some of the old fragility.

98ec7f96c8 Make the v*printf() functions in libsa return int instead of void.
This makes them compatible with the C standard signatures, avoiding
spurious mismatch errors in the places where the oddball requirements
of standalone code end up putting two declarations of the same function
in play.

c5e6cf9373 Add vsnprintf() to libsa. Alpha-sort the printf prototypes in stand.h.
I'm not sure why the v*printf() functions in libsa return void instead of
int, but this maintains that convention for the new function.

2794ca713b Fix build of stand with base gcc
* Make autoboot() a static function in stand/common/boot.c, so it does
  not shadow local variables in gptboot.c and zfsboot.c.
* Remove -Winline from the Makefiles for gptboot, gptzfsboot and
  zfsboot, as gcc will always fail to inline some functions, and there
  is nothing we can do about it.
* For gcc <= 4.2.1, silence -Wuninitialized for isoboot, as it produces
  a false positive warning.
* Remove deprecated and unnecessary -mcpu=i386 flag from stand/defs.mk,
  as there is already a -march=i386 flag further in the file.

356f4f83c1 Pass a struct devdesc to the format commands. Use proper type rather
than doing weird type-punning that happened to work because the size
was right. We copied a zfs devdesc into a disk_devdesc and then after
passing through a NULL pointer reinterpreted it as a
zfs_devdesc. Instead, pass the base devdesc around and 'upcase' when
we know the types are right.

This has the happy side effect of fixing a gcc warning about bad
type punning.

63159784eb Teach ufs_module.c about bsd labels and probe 'a' partition.
If the check for a UFS partition at offset 0 on the disk fails, check
to see if there's a BSD disklabel at block 1 (standard) or at offset
512 (install images assume 512 sector size). If found, probe for UFS
on the 'a' partition.

This fixes UEFI booting images from a BSD labeled MBR slice when the
'a' partiton isn't at offset 0. This is a stop-gap fix since we plan
on removing boot1.efi in FreeBSD 12. We can't easily do that for 11.2,
however, hence the short MFC window.

46b8c82e97 - Unbreak booting sparc64 kernels after the metadata unification in
r329190; sparc64 kernels are always 64-bit but with that revision
  in place, the loader was treating them as 32-bit ones.
- In order to reduce the likelihood of this kind of breakage in the
  future, #ifdef out md_load() on sparc64 and make md_load_dual() -
  which is currently local to metadata.c anyway - static.
- Make md_getboothowto() - also local to metadata.c - static.
- Get rid of the unused DTB pointer on sparc64.

Harry Schmalzbauer reports that some firmware, in his experience, trips

this is due to some confusion with the label and the path on the ESP to
boot1.efi.

Regardless, Harry found that renaming the label seems to fix it.

0b8d8dcffd Add isoboot(8) for booting BIOS systems from HDDs containing ISO images.
This is part of a project for adding the ability to create hybrid CD/USB boot
images. In the BIOS case when booting from something that isn't a CD we need
some extra boot code to actually find our next stage (loader) within an
ISO9660 filesystem. This code will reside in a GPT partition (similar to
gptboot(8) from which it is derived) and looks for /boot/loader in an
ISO9660 filesystem on the image.

9c579660b9 Default loader.conf: Drop efi_max_resolution to 1x1
Effectively disabling the mode changing bits in the loader. No matter which
way we go with it, it seems to be wrong- either the firmware doesn't change
the resolution and reports the resolution we requested, or the firmware
changes the resolution and doesn't report the resolution we requested. It
some cases, it does the right thing, but the bad cases outweight those.

Interested individuals can still set efi_max_resolution to 1080p or whatnot
in loader.conf(5) to restore the new behavior, but the new behavior does not
work out well for many cases.

The drawer module becomes a little easier to navigate through without all of

The previous iteration of this assumed that {module}_load was set. In the
old world order of default loader.conf(5), this was probably a safe
assumption given that we had almost every module explicitly not-loaded in

In the new world order, this is no longer the case, so one could delete a
_load line inadvertently while leaving a _name, _type, _flags, _before,
_after, or _error. This would have caused a confusing Lua error and borked
module loading.
