In case the firmware falls through to executing startup.sh, populate it
with the name of our boot loader. In normal operation this should not be
necessary but may allow the system to boot if it would otherwise just
remain at a shell prompt.

Both objdump and nm are equally capable of reporting undefined symbols.
This gets us a step closer to building without binutils as we have an nm

Fix EFI boot support when presented with multiple valid boot partitions
across multiple devices.
It now prefers to boot from partitions that are present on the underlying
device that the boot1 image was loaded from. This means that it will boot
from the partitions on device the user chose from EFI boot menu in
preference to those on other devices.
Also fixed is the recovery from a failed attempt to boot, from a seemingly
valid partition, by continuing to trying all other available partitions
no matter what the error.
boot1 now use * to signify a partition what was accepted from the preferred
device and + otherwise.
Finally some error messages where improved and DPRINTF's with slowed boot
to aid debugging.
ZFS will still be preferred over UFS when both are available on the boot
device.

EFI was mixing caching in two separate places causing issues when multiple
partitions where tested.
Eliminate this by removing fsstat and re-factoring fsread into fsread_size,
adding basic parameter validation.
Also:
* Enhance some error print outs.
* Fix compilation under UFS1_ONLY and UFS2_ONLY
* Use sizeof on vars instead of structs.
* Add basic parameter validation to fsread_size.

This builds on the modular EFI loader support added r294060 adding a
module to provide ZFS boot support on EFI systems.
It should be noted that EFI uses a fixed size memory block for all
allocations performed by the loader so it may be necessary to tune this
size.
For example when building an image which uses mfs_root e.g. mfsbsd, adding
the following to /etc/make.conf would be needed to prevent EFI from running
out of memory when loading the mfs_root image.
EFI_STAGING_SIZE=128

As the in-tree GCC does not support __attribute__((ms_abi)) EFI can only
be built with Clang.
The EFI loader and boot1 validated this, but unused libefi was still built
causing issues under GCC after warnings where enabled by r293724.
Disable building all of EFI when the selected compiler is GCC.

Set WARNS if not set for EFI boot code and fix the issues highlighted by
setting it.
Most components are set to WARNS level 6 with few being left at lower
levels due to the amount of changes needed to fix at higher levels.
Error types fixed:
* Missing / invalid casts
* Missing inner structs
* Unused vars
* Missing static for internal only funcs
* Missing prototypes
* Alignment changes
* Use of uninitialised vars
* Unknown pragma (intrinsic)
* Missing types etc due to missing includes
* printf formatting types

r279533 increased the boot1 size from 64k to 128k but didn't regenerate the
fat templates, hence the change was never activated.
With recent and upcoming changes the efi boot1 binary is now > 64k.
To avoid fat corruption in the created boot images regenerate the
templates to activate the boot1 size increase.

EFI return values set the high bit to indicate an error. The log
messages changed here are printed only in the case of an error,
so including the error bit is redundant. Also switch to decimal to
match the error definitions (in sys/boot/efi/include/efierr.h).

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
Currently rescue/rescue and sys/modules are still not connected.

The function was defined as taking 4 parameters and returning EFI_STATUS,
but all existing callers (in asm code) passed only two parameters and don't
use the return value. The function signature now matches that usage, and
doesn't refer to efi-specific types.
Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.
The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.

It's necessary to reset the screen to make sure any vendor pixels are
gone when we start boot1. In the Lenovo X1 (3rd gen), this is the
only way to clear the screen. Previously, the Lenovo logo would only
disappear after the kernel started scrolling the display.
After resetting the screen, EFI could put us in the worst LCD mode
(oversized characters), so we now find the largest mode we can use and
hope it's the most appropriate one (it's not trivial to tell what's
the correct LCD resolution at this point). It's worth noting that the
final stage loader has a 'mode' command that can be used to switch
text modes.
While there, enable the software cursor, just like in the legacy boot
mode.
