So far a multiplexed monitor started disabled. Restore this property for
the new way of configuring by moving the monitor initialization before
all devices (the last one to attach to a char-mux will gain the focus).
Once we have a real use case for that, we may also consider assigning
the initial focus explicitly.

The 'quit' Monitor command (implemented by do_quit()) calls
exit() directly, this is problematic under QMP because QEMU
exits before having a chance to send the ok response.
Clients don't know if QEMU exited because of a problem or
because the 'quit' command has been executed.
This commit fixes that by moving the exit() call to the main
loop, so that do_quit() requests the system to quit, instead
of calling exit() directly.

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

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.

What is known today as bdrv_open2 becomes the new bdrv_open. All remaining
callers of the old function are converted to the new one. In some places they
even know the right format, so they should have used bdrv_open2 from the
