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.

- We should be setting a known graphics mode on conout, but we aren't.
- We shouldn't be setting gop mode if we didn't find a good resolution to
set, but we were. This made efi_max_resolution=1x1 effectively worthless,
since it would always set gop mode 0 if nothing else.
Harry Schmalzbauer reports that some firmware, in his experience, trips
over the ESP we install due to the volume label. It has been theorized that
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.

boot1 is too early to be deciding a good resolution. Console modes don't map
cleanly/predictably to actual screen resolutions, and GOP does not reflect
the actual screen resolution after a console mode change. Rip it out.
Add an efi-autoresizecons command to loader to choose an optimal screen
resolution based on the current environment. We'll explicitly execute this
later, preferably before we draw anything of value but after we load config
and pick up any tunables we may need to decide where we're going.
This method also allows us to actually pass the correct framebuffer
information on to the kernel.
UGA autoresizing is not implemented because it doesn't have the kind of mode
enumeration that GOP does. If an interested person with relevant hardware
could get in contact, we can take a look at implementing UGA autoresize.
This effectively "fixes" the breakage caused by r327058, but doesn't
actually set the resolution correctly until the interpreter calls
efi-autoresizcons. The lualoader version of this has been included for
reference; the forth equivalent will follow.

of utf8_to_ucs2. In practice, we'll never see this though since we
pass utf8_to_ucs2 a well formed string.

utf8_to_ucs2 in boot1.efi. We need to initialise the ucs2 output string
so it will allocate space, and use the return value to determine if the
call was successful.

Use simple "foo" rather than "${.CURDIR}/foo" to include Makefile.fat
since the former works when including this Makefile from else
where. Also, use full path from ${BOOTSRC} to the FAT templates for
similar reasons. It doesn't change anything in base FreeBSD, but
allows us to have a custom boot1.efi more easily (though that will be
short-lived for us, it may also be helpful for others).

This patch allows to scan all display modes in boot1 as loader does.
Before system tried to select optimal display mode by sequential scan of
modes and if error then stop scanning. This way is not good, because
if mode N is not present, mode N+1 may exist.
In loader we use conout->Mode->MaxMode to identify maximum number of modes.
This commit is to use same way in boot1 as in loader.

Remove the now-useless dependency on ufsread.c. In some cases, it was
