Up to now "select without attention" was handled the same way as
"select with attention". According to
http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt
select without ATN sends the CDB (Command Descriptor Block) directly,
whereas select with ATN sends one message phase byte
followed by 6, 10, or 12 command phase bytes.
The attached patch implements the behaviour described above.

8baf73adf6 (qdev/isa: convert fdc)
breaks MIPS Malta:
Tried to create isa device isa-fdc with no isa bus present
Fix this by creating an isa bus for piix4.
This change also requires some more qdev related changes
(similar changes were applied to pc.c) and allows
cleaning of piix3/piix4 code.
Thanks to Gerd Hoffmann for his hints.

This file is used by the QDict stress test, it adds 5k nodes
on the dictionary and performs various operations.
My original file had 21k entries and almost 400k of size. After

size.
There are ways to generate this kind of data dynamically, but

With this commit monitor_handle_command() will be able to setup a
QDict with arguments to command handlers.
However, the current 'args[]' method is still being used, next
changes will port commands to get their arguments from the dictionary.
Two changes are worth noting:
1. The '/' argument type always adds the following standard keys in the
dictionary: 'count', 'format' and 'size'. This way, the argument
name used in the 'args_type' string doesn't matter
2. The optional argument type '?' doesn't need to pass the additional
'has_arg' argument, hanlders can do the same check with qdict_haskey()

Current handlers argument types, as defined in qemu-monitor.hx file,
are a sequence of chars where each one represents one argument type
of the command handler. The number of chars is also used to know how
many arguments a given handler accepts.
This commit defines a new format, which makes mandatory the use of
a name for each argument.
For example, do_eject() command handler is currently defined as:
{ "eject", "-fB", do_eject, ... }
With the new format it becomes:
{ "eject", "force:-f,filename:B", do_eject, ... }
This way the Monitor will be capable of setting up a dictionary, using
each argument's name as the key and the argument itself as the value.
This commit also adds two new functions: key_get_info() and
next_arg_type(), both are used to parse the new format.
Currently key_get_info() consumes the 'key' part of the new format and
discards it, this way the current parsing code is not affected by this
change.

Some functions exported to be used by the Monitor as command
handlers are also called in other places as regular functions.
When those functions got ported to use the Monitor dictionary
to pass argments, the callers will have to setup a dictionary
to be able to call them.
To avoid this problem, this commit add wrappers to those functions,
so that we change the wrapper to accept the dictionary, letting
the current functions as is.
The following wrappers are being added:
- do_help_cmd()
- do_pci_device_hot_remove()

QDict is a high-level dictionary data type that can be used to store a
collection of QObjects. A unique key is associated with only one
QObject.
The following functions are available:
- qdict_new() Create a new QDict
- qdict_put() Add a new 'key:object' pair
- qdict_get() Get the QObject of a given key
- qdict_del() Delete a 'key:object' pair
- qdict_size() Return the size of the dictionary
- qdict_haskey() Check if a given 'key' exists
Some high-level helpers to operate on QStrings and QInts objects
are also provided.

Rebased version of Anthony's patch: Allow to specify more than one
monitor terminal via the -monitor command line switch. This is
particularly useful when libvirt or some other management tool already
occupies the primary monitor but you need another one for debugging.
The current clumsy workaround is to multiplex such additional terminals
over a qemu character device (e.g. -serial mon:<device>).
