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.

Along the tlb hit path, we were modifying the variables holding the input
register numbers, which lead to incorrect expansion of the tlb miss path.
Fix this by extracting the tlb hit path to separate functions with their
own local variables. This also makes the difference between softmmu and
user-only easier to read.

Single-stepping was not properly updating npc, resulting in some
instructions being executed twice. In addition, we were emitting
dead code at the end of the TB.
Fix both by teaching gen_goto_tb to avoid goto_tb for single-step
and removing the special-case code in gen_intermediate_code_internal.

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

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.
