fe4709c915 BERI isn't BTX, so we don't have to provide exit(). Just remove it
since it's unused.

db180ae55c stand: Add /boot/overlays to allow separation of overlays from base FDT
This matches directory structure used commonly in Linux-land, and it's
cleaner than mixing overlays into the existing module paths. Overlays are
still mixed in by specifying fdt_overlays in loader.conf(5).

349b6dad63 Use <stand.h> instead of <inttypes.h> and <stdio.h> in boot code.
In the freestanding boot compile environment, standard headers are not
available.  Curiously, only building with clang exposed this as compiles
with external GCC still succeeded.

9433594417 Define __dmadat after #include'ing ufsread.c.
The __dmadat variable is a statically allocated I/O buffer.  The type is
declared in the ufsread.c source file and clang warns if a variable is
defined before it's type is declared.

48ccf80238 Use 'extern uint8_t' instead of 'extern void' for external symbols.
The beri boot loaders depend on symbols defined in linker scripts or
assembly files.  The boot loaders do not care about the type of these
symbols but just want to extract a pointer to them.  Older versions of
GCC permitted external symbols to be declared of type 'void' and then
'&foo' generated a void pointer to the memory at the symbol's address.
However, void objects are not valid C and newer versions of GCC error if
these are used.  Instead, declare these symbols as being bytes (or
an array of bytes in the cheri_sdcard_vaddr case).

a9ca11cb39 Don't clobber system LDFLAGS for beri boot loaders.
Prior to r325114, bsd.init.mk was included after assignments to CFLAGS and
LDFLAGS in these Makefiles.  After r325114, bare assignments (= rather than
+=) lost system-assigned default values that are needed when compiling with
an external toolchain.  CFLAGS in both Makefiles already uses +=.  This
commit changes LDFLAGS to use +=.  While here, depend on the LDFLAGS update
in the parent Makefile.inc to set -nostdlib.

6bc860372d Interact is always called with NULL. Simplify code a little by
removing this argument, and expanding when rc is NULL. This
effectively completes the back out of custom scripts for tftp booted
loaders from r269153 that was started in r292344 with the new path
tricks that obsoleted it.

25c2f4cb95 Move loader help file definitions to being 100% inside of loader.mk.
HELP_FILES is a loader only thing, so move it to loader.mk. Only
generate the help file if HELP_FILES is defined. Adjust Makefiles to
new convention. Fix a few cases where ${.CURDIR}/ was missing
resulting in missing bits from the help files.

6562843997 Remove the 'mini libstand in libstand' that util.[ch] provided. These
weren't needed, and their existance interfered with things in subtle
ways. One of these subtle ways was that malloc could be different
based on what files were included when (even within the same .c file,
it turns out). Move to a single malloc implementation as well by
adding the calls to setheap() to gptboot.c and zfsboot.c. Once upon a
time, these boot loaders strove to not use libstand. However, with the
proliferation of features, that striving is too hard for too little
gain and lead to stupid mistakes.

This fixes the GELI-enabled (but not even using) boot environment. The
geli routines were calling libstand malloc but zfsboot.c and gptboot.c
were using the mini libstand malloc, so this failed when we tried to
probe for GELI partitions. Subtle changes in build order when moving
to self-contained stand build in r326593 toggled what it used from one
type to another due to odd nesting of the zfs implementation code that
differed subtly between zfsloader and zfsboot.

it out unti that can be sorted out.

c83457486b Fix regression with lua import
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.

8a4217aacf Move some more common stuff up to Makefile.inc. In particular, the no
simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.
