then iterate on the next files and try loading them as dtb overlays.
Fix this by checking the type one more time.

This adds tslog_init, which allocates a 2MB buffer for recording
timestamped events; and tslog_publish, which takes the buffer and
passes it to the kernel as a "preloaded module". These functions
will be used in a later commit.

At present this only supports x86, due to the use of the rdtsc

A bug in the loader's bzipfs & gzipfs filesystems caused compressed
kernel and modules not to work on EFI systems with a veriexec-enabled
loader. Since the size of files in these filesystems are not known
_a priori_ `stat` would initialize the size to -1 and the loader would
then hang in an infinite loop while trying to seek (read) to the end
of file since the loop termination condition compares the current
offset to that negative target position.

According to comments in the Makefile, to make pxeboot work we need to
have crt0.o first. This is needed because the simplified loader in
pxeboot assumes that the startup code is at offset 0 in this binary. In
normal booting, the start address can be obtained from headers of the
binary, but since pxeboot encodes this as a pure binary, it has no way
of knowing where that is and assumes 0. Added comments to that effect
in the Makefile.
We've done this by adding it to OBJS before all the other .o's are
added. However, there's a problem. This also adds it to the CLEANFILES
variable, which causes it to be removed from multiple places. The
dependencies may also cause it to be re-built at a time that's after
boot2 is built. This causes installs to fail because at install time
boot2 is considered to be out of date and the programs to rebuild it are
no longer in the path.
Cope with this problem by just adding it to LDFLAGS instead.

Add a man page for gptboot.efi. Describe when and how to use this as it differs
from the BIOS cases. Include cross reference for the preferred method described
in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to
the other.
This man page was heavily copied from the gptboot.8 man page by Warren Block.
They are different enough to need separate man pages for clarity, but there's
enough similarity that I worry about the duplication. In the really long term,
gptboot(8) will disappear, so having the same info here will help when that
day comes. In the short to medium term, the information is likely to not
change in gptboot(8) and any changes to gptboot.efi(8) will be easier to
make in a separate copy.
loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have
referenced gptboot.efi(8) from there.

LLVM12 complains if you change the symbol binding:
`error: _longjmp changed binding to STB_GLOBAL`
In this case LLVM actually ignored the weak directive and used the
later .global, but GNU as would mark the symbol as weak.
None of the other architectures mark the libsa _setjmp as weak so
just drop this directive.
This warning is very rarely useful (inline is a hint and not mandatory).
This flag results in many warnings being printed when compiling C++
code that uses the standard library with GCC.
This flag was originally added in back in r94332 but the flag is a no-op
in Clang ("This diagnostic flag exists for GCC compatibility, and has no
effect in Clang"). Removing it should make the GCC build output slightly

Add some basic multiboot2 infrastructure to the EFI loader in order to
be capable of booting a FreeBSD/Xen dom0 when booted from UEFI.
Only a very limited subset of the multiboot2 protocol is implemented
in order to support enough to boot into Xen, the implementation
doesn't intend to be a full multiboot2 capable implementation.
Such multiboot2 functionality is hooked up into the amd64 EFI loader,
which is the only architecture that supports Xen dom0 on FreeBSD.
The options to boot a FreeBSD/Xen dom0 system are exactly the same as
on BIOS, and requires setting the xen_kernel and xen_cmdline options
in loader.conf.

This mirrors the functionality of the BIOS amd64 bi_load function,
