b92c2c907e Add comments describing the bootargs handoff between loader(8) and gptboot
or zfsboot, when loader(8) is the BTX loader.  No functional changes.

52c0ec1455 Restore the ability to override the disk unit/partition at the boot: prompt
in gptboot.

When arch-independent geli support was added, a new static 'gdsk' struct
was added, but there was still a static 'dsk' struct, and when you typed
in an alternate disk/partition, the string was parsed into that struct,
which was then never used for anything.  Now the string gets parsed into
gdsk.dsk, the struct that's actually used.

02c4bf4391 stand: remove CLANG_NO_IAS from btx and gptboot
Many components under stand/ had CLANG_NO_IAS added when Clang's
Integrated Assembler (IAS) did not handle .codeNN directives.  Clang
gained support quite some time ago, and we can now build stand/ with
IAS.

Note that in some cases there are small differences in the generated
output, so CLANG_NO_IAS should be removed only after testing (or after
finding no differences in the output).

4e6c8e6d83 isoboot, gptboot: Fix WITHOUT_LOADER_GELI (gptboot) and isoboot in general
gptboot was broken when r316078 added the LOADER_GELI_SUPPORT #ifdef to
not pass geliargs via __exec.  KARGS_FLAGS_EXTARG must not be used if we're
not going to pass an additional argument to __exec.

c1418270b2 Extend loader(8) geli support to all architectures and all disk-like devices.
This moves the bulk of the geli support from lib386/biosdisk.c into a new
geli/gelidev.c which implements a devsw-type device whose dv_strategy()
function handles geli decryption. Support for all arches comes from moving
the taste-and-attach code to the devopen() function in libsa.

After opening any DEVT_DISK device, devopen() calls the new function
geli_probe_and_attach(), which will "attach" the geli code to the open_file
struct by creating a geli_devdesc instance to replace the disk_devdesc
instance in the open_file. That routes all IO for the device through the
geli code.

A new public geli_add_key() function is added, to allow arch/vendor-specific
code to add keys obtained from custom hardware or other sources.

With these changes, geli support will be compiled into all variations of
loader(8) on all arches because the default is WITH_LOADER_GELI.

ec82884e87 Revert r335276
This was causing issues for people booting.
I will likely bring this back as an optional feature, similar to
boot0sio, like gptboot-serial or something.

62bd02cee5 stand: move libgeliboot into libsa.
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.

6fee3bb8e1 gptboot, zfsboot, gptzfsboot: Enable the video and serial consoles early
Normally the serial console is not enabled until /boot.config is read and
we know how the serial console should be configured.  Initialize the
consoles early in 'dual' mode (serial & keyboard) with a default serial
rate of 115200. Then serial is re-initialized once the disk is decrypted
and the /boot.config file can be read.

This allows the GELIBoot passphrase to be provided via the serial console.

073193ed51 Fix build of stand with base gcc
* Make autoboot() a static function in stand/common/boot.c, so it does
  not shadow local variables in gptboot.c and zfsboot.c.
* Remove -Winline from the Makefiles for gptboot, gptzfsboot and
  zfsboot, as gcc will always fail to inline some functions, and there
  is nothing we can do about it.
* For gcc <= 4.2.1, silence -Wuninitialized for isoboot, as it produces
  a false positive warning.
* Remove deprecated and unnecessary -mcpu=i386 flag from stand/defs.mk,
  as there is already a -march=i386 flag further in the file.

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.
