This should have no functional change. Move compiling the sha256, sha512
and md5 hash functions up into libsa to allow them to be used elsewhere
in the boot loader when geli isn't configured. Since libsa is a .a, these
won't wind up in any boot loader that doesn't reference them, so should
be a nop.

liblua now provides a loader.has_feature() function to probe the loader
binary for features advertised. name => desc mappings are provided in
loader.features to get a list of all of the features loader *can*
support. core.hasFeature is provided as a shim to loader.has_feature
so that individual consumers don't need to think about the logic of the
loader module not providing has_feature; we know that means the feature
isn't enabled.
The first consumer of this will be EARLY_ACPI to advertise that the
loader binary probes for ACPI presence before the interpreter has
started, so that we know whether we can trust the presence of acpi.rsdp
as relatively authoritative. In general, it's intended to be used to
avoid breaking new scripts on older loaders within reason.
This will be used in lua as `core.hasFeature("EARLY_ACPI")`, while the
C bits of loader will `feature_enable(FEATURE_EARLY_ACPI)`.

zfs lives in libsa. However, it depends on nvstore (and other things)
that are in common. Fix part of this layering violation by splitting
nvstore into a libsa piece (which is the base implementation) and
keeping a much smaller common piece (to implement the nvstore
command). This just leaves zfs' knowledge of device names that's
specific to common and its calling platform specific init code to
resolve. Add a nvstore.h file for these two parts to communicate private
things and move the public nvstore api from bootstrap.h to stand.h.

The BIOS loader operates in a very constrained environment. The messages
for the super block integrity tests take up about 12k of space. Compile
them out for the BIOS loader, while leaving it intact for all other
loaders that aren't space constrained. These aren't used in the 'super
tiny' *boot* programs, so no adjustment is needed there.
We reply on the fact that (a) i386 doesn't support 32-bit UEFI booting
and (b) LIBSA_CPUARCH is "i386" when building on both i386 and when
we're building the 32-bit libsa32 library.
This saves about 12k of space for this constrained envrionment and will
take a bit of the pressure off some machines where the loader has grown
too big for their BIOS (see comments in i386/loader/Makefile for
details).

When we load an ELF file (kernel or module) we do seek(2) a lot to
parse/load the different sections of the ELF file.
Protocol like TFTP suffers a lot from this as there is no resume or
a way to start the tranfer from a specified offset in the file.
fs_preload is added to help those protocol.
Call preload just after opening the ELF file that we need to load so
the underlying method can cache the hole file and then read/lseek operations
are faster.

There was a small window cp was broken. Work around this by using :>

boot_parse_cmdline to parse a command line string
boot_parse_args to parse all the args in a vector
boot_howto_to_env Convert howto bits to env vars
boot_env_to_howto Return howto mask mased on what's set in the environment.
All these routines return an int that's the bitmask of the args
translated to RB_* flags. As a special case, the 'S' flag sets the
comconsole_speed env var. Any arg that looks like a=b will set the env
key 'a' to value 'b'. If =b is omitted, 'a' is set to '1'. This
should help us reduce the number of redundant copies of these routines
in the tree. It should also give a more uniform experience between
platforms.
Also, invent a new flag RB_PROBE that's set when 'P' is parsed. On
x86 + BIOS, this means 'probe for the keyboard, and if it's not there
set both RB_MULTIPLE and RB_SERIAL (which means show the output on
both video and serial consoles, but make serial primary). Others it
may be some similar concept of probing, but it's loader dependent
what, exactly, it means.
These routines are suitable for /boot/loader and/or the kernel,
though they may not be suitable for the tightly hand-rolled-for-space
environments like boot2.

Reduce by 1 the number of crazy libraries we need in stand by moving
geli into libsa (where architecturally it belonged all along). This
just moves things around without any code changes.
OK. We don't really need a bsd.stand.mk, and it was causing a -fPIC
for the toolchain to be added (bogusly) when building on amd64. Pull
all relevant defs back into defs.mk and delete bsd.stand.mk.
This saves about 15-20k on i386 loader and zfsloader which when
combined with Lua give us a lot more stack space in those constrained
environments.
MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the
same, so set them in defs.mk. MAN= is common, so set it here too.
This removes a lot of boring repetition from the Makefiles that added
almost no value.
