0148fde54c Fix exit on 'pci_add' Monitor command
If the user issues one of the following commands to the Monitor:

pci_add pci_addr=auto nic model=None
pci_add pci_addr=auto nic model=?

QEMU will exit, because the function used to perform sanity
checks (qemu_check_nic_model_list()) exits on error.

This function is used by the startup code, where it makes
sense to exit on error, but in the Monitor it doesn't.

Changing qemu_check_nic_model_list() to not exit on error
is not possible though, as it's used by the board init
code (the PC one), where all board specific code must have
void return.

The way I've chosen to fix this was to introduce a new function
called pci_nic_supported(), which checks if the NIC is supported
and returns true or false accordingly.

The new function is used only by the Monitor, it performs the
necessary check and returns an error in case the NIC is not
supported, thus qemu_check_nic_model_list()'s exit is never trigged.

The following should be observed:

1. Only the specified NIC is checked, the default one is assumed
to be supported

2. The NIC query command (model=?) won't work with pci_add, the
right way to do this with the Monitor is to add a new command

72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

d52affa7f6 qdev/scsi: add scsi bus support to qdev, convert drivers.
* Add SCSIBus.
 * Add SCSIDeviceInfo, move device callbacks here.
 * add qdev/scsi helper functions.
 * convert drivers.

Adding scsi disks via -device works now, i.e. you can do:

 -drive id=sda,if=none,...
 -device lsi
 -device scsi-disk,drive=sda

legacy command lines (-drive if=scsi,...) continue to work.

3818318682 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.

The following wrappers are being added:

- do_help_cmd()
- do_pci_device_hot_remove()

d176c495b6 qdev-ify virtio-blk.
First user of the new drive property.  With this patch applied host
and guest config can be specified separately, like this:

  -drive if=none,id=disk1,file=/path/to/disk.img
  -device virtio-blk-pci,drive=disk1

You can set any property for virtio-blk-pci now.  You can set the pci
address via addr=.  You can switch the device into 0.10 compat mode
using class=0x0180.  As this is per device you can have one 0.10 and one
0.11 virtio block device in a single virtual machine.

Old syntax continues to work.  Internally it does the same as the two
lines above though.  One side effect this has is a different
initialization order, which might result in a different pci address
being assigned by default.

Long term plan here is to have this working for all block devices, i.e.
once all scsi is properly qdev-ified you will be able to do something
like this:

  -drive if=none,id=sda,file=/path/to/disk.img
  -device lsi,id=lsi,addr=<pciaddr>
  -device scsi-disk,drive=sda,bus=lsi.0,lun=<n>

751c6a1704 kill drives_table
First step cleaning up the drives handling.  This one does nothing but
removing drives_table[], still it became seriously big.

drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index.  This needs adaption in
*tons* of places all over.

The drives are now maintained as linked list.

pc_init1(), bamboo_init(), mpc8544ds_init().

Don't support addr= in third argument of monitor command pci_add and
second argument of drive_add, because that clashes with their first

Make net_client_init() accept addr=, put the value into struct
NICinfo.  Use it in pci_nic_init(), and remove arguments bus and
devfn.

Don't support addr= in third argument of monitor command pci_add,

Machines "malta" and "r2d" have a default NIC with a well-known PCI
address.  Deal with that the same way as the NIC model: make
pci_nic_init() take an optional default to be used when the user
doesn't specify one.

10ae5a7a98 net: Improve parameter error reporting
As host network devices can also be instantiated via the monitor, errors
should then be reported to the related monitor instead of stderr. This
requires larger refactoring, so this patch starts small with introducing

net_slirp_redir.

eefb4091d2 Don't fail PCI hotplug if no NIC model is supplied (Mark McLoughlin)

 - The error message to show the actual if= argument value. It was showing

 - A bug that makes a block device to be created even when an unsupported if= arg

376253ece4 monitor: Rework API (Jan Kiszka)
Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains
unused for now. All monitor command callbacks are also extended by a mon
parameter so that command handlers are able to pass an appropriate
reference to monitor output services.

For the case that monitor outputs so far happen without clearly
identifiable context, the global variable cur_mon is introduced that
shall once provide a pointer either to the current active monitor (while
processing commands) or to the default one. On the mid or long term,
those use case will be obsoleted so that this variable can be removed
again.

Due to the broad usage of the monitor interface, this patch mostly deals
with converting users of the monitor API. A few of them are already
extended to pass 'mon' from the command handler further down to internal
functions that invoke monitor_printf.

At this chance, monitor-related prototypes are moved from console.h to
a new monitor.h. The same is done for the readline API.

6f338c3469 qemu: PCI device, disk and host network hot-add / hot-remove (Marcelo Tosatti)
Add monitor command to hot-add PCI devices (nic and storage).
    
Syntax is:
    
pci_add pci_addr=[[<domain>:]<bus>:]<slot> nic|storage params
    
It returns the domain, bus and slot for the newly added device on success.
    
It is possible to attach a disk to a device after PCI initialization via
the drive_add command. If so, a manual scan of the SCSI bus on the guest
is necessary.
    
Save QEMUMachine necessary for drive_init.
    
Add monitor command to hot-remove devices, remove device data on _EJ0 notification.
