hd_geometry_guess() picks geometry and translation. Callers can get
the geometry directly, via parameters, but for translation they need
to go through the block layer.
Add a parameter for translation, so it can optionally be gotten just
like geometry. In preparation of purging translation from the block
layer, which will happen later in this series.

When hd_geometry_guess() picks a geometry, it also picks the
appropriate translation, but only when the prior translation hint is
BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior
translation would be passed to the BIOS whether it's suitable for the
geometry or not.
Fortunately, that can't happen. There are just two ways for the
translation hint to get set to something other than
BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=...,
and hd_geometry_guess(). Both set it only when they also set a valid
geometry hint, i.e. one with a non-zero number of cylinders.
Since hd_geometry_guess() returns right away when it finds a valid
geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in
the remainder of the function.
Assert this, and simplify accordingly.

vvfat creates a virtual VFAT filesystem with a certain logical
geometry that depends on its options. It sets the "geometry hint" to
this geometry. It is the only block driver to do this.
The geometry hint is about about *physical* geometry, and used only by
certain hard disk device models.
vvfat's hint is normally invisible for device models, because
bdrv_open() puts a raw format on top of vvfat's fat protocol. That
raw format is where drive_init() puts the user's geometry (if any),
and where the device model gets it from.
Nobody complained, because the default physical geometry is the same
as vvfat's logical geometry:
opts LCHS def. PCHS
1024,16,63 same
:32: 1024,16,63 same
:16: 1024,16,63 same
:12: 64,16,63 same
Except when you specify :floppy:
opts LCHS def. PCHS
:floppy: 80, 2,36 5,16,63
:32:floppy: 80, 2,36 5,16,63
:16:floppy: 80, 2,36 5,16,63
:12:floppy: 80, 2,18 2,16,63
Silly thing to do for use with a hard disk.
However, the "raw" format can be suppressed by adding an
redundant-looking "format=vvfat" to "file=fat:FOO". Then, vvfat's
hint clobbers the user's geometry, i.e. -drive options cyls, heads,
secs get silently ignored. Don't do that.
No change without format=vvfat. With it, the user's hard disk
geometry (-drive options cyls, heads, secs) is now obeyed, and the
default hard disk geometry with :floppy: now matches the one without
format=vvfat.

Unless parameter ":floppy:" is given, vvfat creates a virtual image
with DOS MBR defining a single partition which holds the FAT file
system. The size of the virtual image depends on the width of the
FAT: 32 MiB (CHS 64, 16, 63) for 12 bit FAT, 504 MiB (CHS 1024, 16,
63) for 16 and 32 bit FAT, leaving (64*16-1)*63 = 64449 and
(1024*16-1)*64 = 1032129 sectors for the partition.
However, it screws up the end of the partition in the MBR:
FAT width param. start CHS end CHS start LBA size
:32: 0,1,1 1023,14,63 63 1032065
:16: 0,1,1 1023,14,55 63 1032057
:12: 0,1,1 63,14,55 63 64377
The actual FAT file system nevertheless assumes the partition has
1032129 or 64449 sectors. Oops.

Commit 5bbdbb46 moved it to block.c because "other geometry guessing
functions already reside in block.c". Device-specific functionality
should be kept in device code, not the block layer. Move it back.
Disk geometry guessing is still in block.c. To be moved out in a
later patch series.
Bonus: the floppy type used in pc_cmos_init() now obviously matches
the one in the FDrive. Before, we relied on
bdrv_get_floppy_geometry_hint() picking the same type both in
fd_revalidate() and in pc_cmos_init().

In our disassembly code, the bfd_vma type is always 64 bits,
even if the target's virtual address width is only 32 bits. This
means that when we print out addresses we need to truncate them
to 32 bits, to avoid odd output which has incorrectly sign-extended
a value to 64 bits, for instance this ARM example:
0x80479a60: e59f4088 ldr r4, [pc, #136] ; 0xffffffff80479a4f
(It would also be possible to truncate before passing the address
to info->print_address_func(), but truncating in the final print
function is the same approach that binutils takes to this problem.)
