Move most arch/i386 files to arch/x86, and adjust the contents of the
Makefiles and the include/bits/*.h headers to reflect the new
locations.
This patch makes no substantive code changes, as can be seen using a
rename-aware diff (e.g. "git show -M5").
This patch does not make the pcbios platform functional for x86_64; it
merely allows it to compile without errors.

[image] Simplify image management commands and internal API
Remove the name, cmdline, and action parameters from imgdownload() and
imgdownload_string(). These functions now simply download and return
an image.
Add the function imgacquire(), which will interpret a "name or URI
string" parameter and return either an existing image or a newly
downloaded image.
Use imgacquire() to merge similar image-management commands that
currently differ only by whether they take the name of an existing
image or the URI of a new image to download. For example, "chain" and
"imgexec" can now be merged.
Extend imgstat and imgfree commands to take an optional list of
images.
Remove the arbitrary restriction on the length of image names.

[prefix] Delay initrd image copy until memory map is ready
initrd_init() calls umalloc() to allocate space for the initrd image,
but does so before hide_etherboot() has been called. It is therefore
possible for the initrd to end up overwriting iPXE itself.
Fix by converting initrd_init() from an init_fn to a startup_fn.

[lkrnprefix] Copy command line before installing iPXE
The command line may be situated in an area of base memory that will
be overwritten by iPXE's real-mode segments, causing the command line
to be corrupted before it can be used.
Fix by creating a copy of the command line on the prefix stack (below
0x7c00) before installing the real-mode segments.

Allow an initrd (such as an embedded script) to be passed to iPXE when
loaded as a .lkrn (or .iso) image. This allows an embedded script to
be varied without recompiling iPXE.
