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

The EFI loader and boot1 validated this, but unused libefi was still built

Set WARNS if not set for EFI boot code and fix the issues highlighted by

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

r279533 increased the boot1 size from 64k to 128k but didn't regenerate the

With recent and upcoming changes the efi boot1 binary is now > 64k.

If ExitBootServices fails due to a changed efi_mapkey then GetMemoryMap
must be called again. In this case it is also possible for the memory

Also roll bi_add_efi_data_and_exit into bi_load_efi_data as there's no

The EFI memory map may change before or during the first
ExitBootServices call. In that case ExitBootServices returns an error,
and GetMemoryMap and ExitBootServices must be retried.
Glue together calls to GetMemoryMap(), ExitBootServices() and storage of
(now up-to-date) MODINFOMD_EFI_MAP metadata within a single function.
That new function - bi_add_efi_data_and_exit() - uses space previously
allocated in bi_load_efi_data() to store the memory map (it will fail if
that space is too short). It handles re-calling GetMemoryMap() once to
update the map key if necessary. Finally, if ExitBootServices() is
successful, it stores the memory map and its header as MODINFOMD_EFI_MAP
metadata.
ExitBootServices() calls are now done earlier, from within arch-
independent bi_load() code.

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.
