ffs_subr.c requires calculate_crc32c() from libkern. Unfortunately we
cannot just add libkern/crc32.c to libstand because crc32.o is already
compiled from contrib/zlib/crc32.c. Use the include trick to rename
the source.
Note that libstand also provides crc32.c which seems to be unused.

to it being a common name elsewhere. Rename the old kzip one
to subr_inflate.c.
This actually fixes the build issues on sparc64 that my inclusion of
.PATH ${SYSDIR}/kern created in r336244, so also revert the broken
workaround I committed in r336249.
This slipped passed me because apparently, I never did a clean build.
boot_parse_arg to parse a single arg
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.

Move the libzfs stuff into libsa. There's no need for it to be a
separate library. The separate library adds to the issues of build
ordering that we see from time to time. Move the filesystem support
into libsa, like all the other filesystem support rather than making
zfs the odd-duck out.
Discussed with: allanjude@
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.
since they suffice. Create xlocale_private.h which provides the most
minimal locale implementation we can get away with. Add strtoll and
strtoull from libc.
Specifically reading is done if ffs_sbget() and writing is done
in ffs_sbput(). These functions are exported to libufs via the
sbget() and sbput() functions which then used in the various
filesystem utilities. This work is in preparation for adding
subperblock check hashes.
No functional change intended.

strnlen is not used at the moment, but it will be when libfdt gets updated.
Prepare for the not-so-distant future by pulling in strnlen.
Noticed because: segfault in ld.bfd due to strnlen missing
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.

Move kernel includes and libsa includes together at the top of defs.mk
Move all machine specific defines from Makefile.inc to their friends
in defs.mk.
Add comments and remove now useless junk after the move.
