blockdev: Fix drive_add for drives without media

Watch this:

(qemu) drive_add 0 if=none
    (qemu) info block
    none0: type=hd removable=0 [not inserted]
    (qemu) drive_del none0
    Segmentation fault (core dumped)

add_init_drive() is confused about drive_init()'s failure modes, and...

blockdev: Make drive_add() take explicit type, index parameters

Before, type & index were hidden in printf-like fmt, ... parameters,
which get expanded into an option string. Rather inconvenient for
uses later in this series.

New IF_DEFAULT to ask for the machine's default interface. Before,...

Rearrange block headers

Changing block.h or blockdev.h resulted in recompiling most objects.

Move DriveInfo typedef and BlockInterfaceType enum definitions
to qemu-common.h and rearrange blockdev.h use to decrease churn.

blockdev: Collect block device code in new blockdev.c

Anything that moves hundreds of lines out of vl.c can't be all bad.

kill dead nic unplug code.

Cleanup on unplug happens via qdev->exit() callback now.

drive cleanup fixes.

Changes: * drive_uninit() wants a DriveInfo now. * drive_uninit() also calls bdrv_delete(),
so callers don't need to do that. * drive_uninit() calls are moved over to the ->exit()
callbacks, destroy_bdrvs() is zapped. * setting bdrv->private is not needed any more as the...

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 15cc9235840a22c289edbe064a9b3c19c5f49896,...

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...

kill drives_opt

cleanup pretty simliar to the drives_table removal patch:
- drop the table and make a linked list out of it.
- pass around struct pointers instead of table indices.

switch -drive to QemuOpts.

Demo QemuOpts in action ;)

Implementing a alternative way to specify the filename should be
just a few lines of code now once we decided how the cmd line syntax
should look like.

Don't leak VLANClientState on PCI hot remove

destroy_nic() requires that NICInfo::private by a PCIDevice pointer,
but then goes on to require that the same pointer matches
VLANClientState::opaque.

That is no longer the case for virtio-net since qdev and wasn't...

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....
