stand: Separate base and cli parts of nvstore

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.

Pull together the nearly identical copies of set_currdev in i386,

and ofw and uboot do handle these setting differently, leave them be for

stand: Move dev_cleanup into libsa

Since dev_cleanup() walks through all the devsw devices with dv_cleanup
rotuines, move it into libsa rather than having it in
'common'. Logically, it operates only on things that are in libsa, and
would never be different for different loaders: either people would call
it as is, or they'd do the loop themselves with 'special' things inline
between calls to cleanup (not that I think that will ever be needed
though).

loader: narrow the scope of gfx frame buffer wrt tg supported kernels

Store whether or not we found a vbefb module (eg, a tg supported kernel)
in the preloaded_file structure. This automatically resets on reload and
eliminates load_elf knowing about any gfx_* interface. Restrict this to
i386, which is the only place it's used. Update libi386 to check in the
preloaded_file struct. Eliminate this from the teken_gfx
structure. Rewrite the parsing code to be more inline. Check this from
the same place we check for a relocatable amd64 kernel.

amd64 UEFI loader: stop copying staging area to 2M physical

On amd64, add a possibility to activate kernel with staging area in place.
Add 'copy_staging' command to control this. For now, by default the
old mode of copying kernel to 2M phys is retained. It is going to be
changed in several weeks.

On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data
increase after the final size is calculated. Add a new command
'staging_slop' to control its size.

Improve staging area resizing, in particular, reallocate it anew if
we cannot grow it neither down nor up.
