If we use larger BIOS image than current 256KB, we would need move reserved
TSS and EPT identity mapping pages. Currently TSS support this, but not
EPT.

Greatly simplify the subpage implementation by not supporting
multiple devices at the same address at different widths. We
don't need full copies of mem_read/mem_write/opaque for each
address, only a single index back into the main io_mem_* arrays.

The ABI-specific types used by linux_binprm and image_info
are different after forcing TARGET_ABI32 on. Which means
that the parameters that load_elf_binary_multi sees are not
those that loader_exec passed. This is inherently broken
and is more trouble than it's worth fixing.

Several commands have code to create a BlockDriverState and open a file.
The bdrv_new_open() function can be used to perform these steps. This
patch converts the qemu-img commands to actually use bdrv_new_open().
Replaced the bdrv_new_open() 'readonly' argument with bdrv_open()-style
flags to support generic flags like BDRV_O_NO_BACKING.

Split up the raw_getlength into separate generic, solaris and BSD

is a complete maze, but to clean it up properly we'd need some

for what variant.

BDRV_O_FILE is only used to communicate between bdrv_file_open and bdrv_open.
It affects two things: first bdrv_open only searches for protocols using
find_protocol instead of all image formats and host drivers. We can easily
move that to the caller and pass the found driver to bdrv_open. Second
it is used to not force a read-write open of a snapshot file. But we never
use bdrv_file_open to open snapshots and this behaviour doesn't make sense
to start with.
qemu-io abused the BDRV_O_FILE for it's growable option, switch it to
using bdrv_file_open to make sure we only open files as growable were
we can actually support that.
This patch requires Kevin's "[PATCH] Replace calls of old bdrv_open" to
be applied first.
