loader: Bump all versions to 3.0
Each incompatible change we make, we bump the major version. We've not
done the bump in a while, so sync everybody to 3.0. Anything older than
3.0 will be given a warning that their boot loader is too old. We check
only the major version, though, so minor versions can still be bumped
for individual loaders (though I honestly doubt we'll ever need to do
that again).

kboot: Initialize hostfs_root sooner (and remove kboot.conf)
Move the initialization of hostfs_root to be a bit sooner. While it
doesn't matter for the default case, we may want to use hostfs files
sooner.
Also, while we're here, remove kboot.conf. It duplicates the command
line and has proven difficult to use. It will be replaced by an early
script that can influence the state of the boot loader before we select
a device to boot from (including strongly suggesting which one to boot
from).

If we are able to open /sys/firmware/fdt, but aren't able to read it,
fall back to /proc/device-tree. Remove comment that's not really true,

kboot: hostfs -- check for llseek failure correctly
The host_* syscalls are all raw Linux system calls, not the POSIX
wrappers that glibc / musl create. So we have to ranage change the
return value of host_llseek correctly to use the negative value hack
that all Linux system calls use.
This fixes a false positive error detection when we do something like
lseek(fd, 0xf1234567, ...); This returns 0xf1234567, which is a negative
value which used to trigger the error path. Instead, we check using the
is_linux_error() and store the return value in a long. Translate that
errno to a host errno and set the global errno to that and return
-1. lseek can't otherwise return a negative number, since it's the
offset after seeking into the file, which by definition is positive.
This kept the 'read the UEFI memory map out of physical memory' from
working on aarch64 (whose boot loader falls back to reading it since
there are restrictive kernel options that can also prevent it), since
the physical address the memory map was at on my platform was like
0xfa008018.

loader/kboot: simplify linker set inclusion a little
Linker set sections are included by default. No need to do so
explicitly. These were bogusly copied from the efi ldscripts. They were
there due to a workaround introduced in 2002 by peter@ for a gcc
upgrade, but whatever bugs necessitated it were filed by 2010 when
rpaulo@ imported the i386 support (though they were copied even though
the objcopy retained them correctly, the gcc bug having been
fixed). They've never been needed.
