qdev/scsi+usb: convert usb-storage to qdev.

Full coverage with properties and everything.  You can add virtual usb
sticks this way now:

  -drive if=none,id=pendrive,path=/some/where
  -device usb-storage,drive=pendrive

-usbdevice disk:/path/to/image continues to work.

Other side effects:
usb storage is listed in 'info block' now.
kvm tree should be able to boot from usb via extboot (untested though).

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()

monitor: New format for handlers argument types

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.

Add wrappers to functions used by the Monitor

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.

Introduce QDict

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.

Introduce QString

QString is a high-level data type that can be used to represent
C strings.

The following functions are available:

- qstring_from_str() Create a new QString
- qstring_get_str()  Get a pointer to the stored string

Note that qstring_get_str() is too low-level for a data type like
this, but it's interesting for quick read-only accesses.

Support for multiple -monitor devices

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>).

do not issue ioctl from within the io thread

According to Documentation/kvm/api.txt, (and well, to common sense),
we should not be calling vcpu ioctls from within the iothread.
Since vcpu initialization issues a vcpu ioctl, move it a little bit
further in time to prevent it.
