We need to include ficl.h after the standard includes, rather than
before them. It changes the generated code in ways that haven't been
completely analyized. This restores the old code generation (as
verified by md5 changing back for zfsloader).
This should restore GPT + ZFS and GPT + ZFS + GELI booting that was
broken in r326585 (or would have been if r326584 hadn't broken the
build).

Don't print when we can't find a file. Copy it instead to the error
buffer. Higher level routines determine if it's appropriate to print
the error message.
Also, remove dead code (labeled bogusly lost functionality) since we
never used that functionality. Remove unused arg from interact() too.

saved register, but in arm EABI it may be either callee-saved or dedicated
to some special purpose (such as a TLS pointer). It appears clang does not
treat it as a callee-saved register (instead using it as another work
register, similar to r12).
Another important side effect of these changes is that saving an extra
register in the push/pop statements keeps the stack aligned to an 8-byte
boundary during the self_reloc() call, as it always should have been.
As stated in the PR...
Essentially the important caller-saved registers are pushed (r0, r1, r9, lr)
before the relocation call, and popped after. Then r8/r9 are saved as usual
for the syscall trampoline, and lr is stored in r8 (now free) as a
callee-saved value before calling into `main`.
The call to `main` can no longer be a tail call because we must restore r9
especially after main returns (although since we have used r8 to hold lr we
must also restore this).

the stand environment that's safe to use (and insulated from whatever
build env you might normally have), stop hacking the bzlib and zlib
sources with sed. There's no longer any need.

Building with the standard system headers isn't a perfect match to the
stand environment. Instead, copy over the files we know are safe to
use and constrain what else is used. We use -nostdinc to achieve this.
This also fixes issues with building 32-bit libraries on amd64
sometimes pulling in the wrong cpufunc.h giving an error now that we
stop on errors. It will also enable an easier transition to lua boot.

latter aren't used. Prefer sys/link_elf.h to link.h so we're only
dependent on the kernel tree. The default installation of link.h just
includes this file, and any benefit from that is outweighed by the
hassle it causes. This reduces the footprint of files needed from the
system includes (or sysroot in buildworld).

Previous to the switch from sys/boot to stand/ zfsboot (used for MBR) did
not support GELI. Now that it is compiled with GELI, it is running out of
space.
zfsldr (which loads zfsboot) was modified to load 256kb in r304321
it's going to be removed soon anyway once the final lingering issues
with kboot are resolved. Go ahead and disconnect it from the build a
little early.
