r351119:
stand: push LIBC_SRC up into defs.mk

Other parts of stand/ that don't use libsa will need to grab bits from libc
shortly. Push LIBC_SRC up to defs.mk in advance of this so that they can use
it, and rename it to LIBCSRC to match the convention of the rest of the *SRC
variables in this file.

r351135:
stand: boot2: fix build with xtoolchain-llvm90

ufsread.c grows a dependency on __ashldi3 with llvm90. Grab ashldi3.c out of
compiler-rt rather than trying to link against libsa (for now).
-Wno-missing-prototypes is necessary to compile ashldi3.c standalone.

r351136:
stand: gptboot: fix build with xtoolchain-llvm90

ufsread.c grows a dependency on __ashldi3 with llvm90. For gptboot, just
start pulling in ashldi3.c ashrdi3.c lshrdi3.c into libsa for all archs as
the number of archs requiring one or more of them keeps growing. qdivrem.c
and quad.h can be trivially kicked out of libsa if we start pulling these
from compiler-rt as qdivrem was only used to implement umoddi3, divdi3,
moddi3 (also in qdivrem.c).

r351412:
stand: boot2: fix amd64-xtoolchain-gcc build

-Wno-missing-declarations is the GCC equivalent of
-Wno-missing-prototypes... this was overlooked in r351135.

There's two files in the sys tree named inflate.c, in addition
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.

Fix sparc64 builds

gcc is complaining about struct infate being defined in a parameter
list. It's inclear how long this has been broken, but the fix is
simple enough.

Create helper functions for parsing boot args.

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_t

Create helper functions for parsing boot args.

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.

Eliminate bsd.stand.mk and -fPIC 32-bit intel builds

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.

Refactoring of reading and writing of the UFS/FFS superblock.
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.

Stop building with the standard system headers.

Building with the standard system headers isn't a perfect match to the

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.
