QList: Introduce QLIST_FOREACH_ENTRY()
Iterate over QList entries, it's needed to call qlist_entry_obj()
to retrieve the stored QObject.
I'm not sure if it's ok to have this, because it's not as easy as
qlist_iter() and the QListEntry data type is now exposed to the
users, which means we have one more struct to be maintained when
we have libqmp.
Adding anyway, as it's more compact and people are asking for it.

Documentation: Add missing texi description for command line options
Some more command line options had entries for command line help,
but documentation for texi and derived formats (man, html, info)
was missing.
For conditional options, the texi documentation was added

This seems reasonable because typically man pages are
shared, and html users expect to see one documentation

Markus Armbruster pointed out:
JSON requires control characters in strings to be escaped. RFC 4627

A string begins and ends with quotation marks. All Unicode
characters may be placed within the quotation marks except for the
characters that must be escaped: quotation mark, reverse solidus, and
the control characters (U+0000 through U+001F).

To correcly enumerate and map ports between the host and the guest, the

Example:
-device virtserialport,name=org.qemu.port.0
This invocation will get us a char device in the guest at:
/dev/virtio-ports/org.qemu.port.0

/dev/vport0p3
This 'name' property is exposed by the guest kernel in a sysfs

virtio-console: qdev conversion, new virtio-serial-bus
This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.
The virtio console is now a very simple qdev device that sits on the
virtio-serial-bus and communicates between the bus and qemu's chardevs.
This commit also includes a few changes to the virtio backing code for
pci and s390 to spawn the virtio-serial bus.
As a result of the qdev conversion, we get rid of a lot of legacy code.
The old-style way of instantiating a virtio console using
-virtioconsole ...
is maintained, but the new, preferred way is to use
-device virtio-serial -device virtconsole,chardev=...
With this commit, multiple devices as well as multiple ports with a
single device can be supported.
For multiple ports support, each port gets an IO vq pair. Since the
guest needs to know in advance how many vqs a particular device will
need, we have to set this number as a property of the virtio-serial
device and also as a config option.
In addition, we also spawn a pair of control IO vqs. This is an internal
channel meant for guest-host communication for things like port
open/close, sending port properties over to the guest, etc.
This commit is a part of a series of other commits to get the full
implementation of multiport support. Future commits will add other
support as well as ride on the savevm version that we bump up here.

raw-posix: Detect legacy floppy via ioctl on linux
Current legacy floppy detection is hardcoded based on source file
name. Make this smarter on linux by attempting a floppy specific
ioctl.
v2:
Give ioctl check higher priority than filename check
s/IDE/legacy/
v3:
Actually initialize 'prio' variable
Check for ioctl success rather than absence of specific failure
v4:
Explicitly mention that change is linux specific.
