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.

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.
* 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.

Remove the now-useless dependency on ufsread.c. In some cases, it was
on the wrong file. But in all cases, we now automatically generate
.depend files, so we don't need it explicitly.
