ca9bd24cf1 block: Rewrite bdrv_close_all()
This patch rewrites bdrv_close_all(): Until now, all root BDSs have been
force-closed. This is bad because it can lead to cached data not being
flushed to disk.

Instead, try to make all reference holders relinquish their reference
voluntarily:

1. All BlockBackend users are handled by making all BBs simply eject
   their BDS tree. Since a BDS can never be on top of a BB, this will
   not cause any of the issues as seen with the force-closing of BDSs.
   The references will be relinquished and any further access to the BB
   will fail gracefully.
2. All BDSs which are owned by the monitor itself (because they do not
   have a BB) are relinquished next.
3. Besides BBs and the monitor, block jobs and other BDSs are the only
   things left that can hold a reference to BDSs. After every remaining
   block job has been canceled, there should not be any BDSs left (and
   the loop added here will always terminate (as long as NDEBUG is not
   defined), because either all_bdrv_states will be empty or there will
   not be any block job left to cancel, failing the assertion).

d8da3cef3b block: Add blk_remove_all_bs()
When bdrv_close_all() is called, instead of force-closing all root
BlockDriverStates, it is better to just drop the reference from all
BlockBackends and let them be closed automatically. This prevents BDS
from getting closed that are still referenced by other BDS, which may
result in loss of cached data.

This patch adds a function for doing that, but does not yet incorporate
it in bdrv_close_all().

64dff52019 block: Make bdrv_close() static
There are no users of bdrv_close() left, except for one of bdrv_open()'s
failure paths, bdrv_close_all() and bdrv_delete(), and that is good.
Make bdrv_close() static so nobody makes the mistake of directly using
bdrv_close() again.

3301f6c6e9 block: Add BB-BDS remove/insert notifiers
bdrv_close() no longer signifies ejection of a medium, this is now done
by removing the BDS from the BB. Therefore, we want to have a notifier
for that in the BB instead of a close notifier in the BDS. The former is
added now, the latter is removed later.

Symmetrically, another notifier list is added that is invoked whenever a
BDS is inserted. We will need that for virtio-blk and virtio-scsi, which
can then remove their op blockers on BDS ejection and set them up on
insertion.

c5acdc9ab4 block: Release named dirty bitmaps in bdrv_close()
bdrv_delete() is not very happy about deleting BlockDriverStates with
dirty bitmaps still attached to them. In the past, we got around that
very easily by relying on bdrv_close_all() bypassing bdrv_delete(), and
bdrv_close() simply ignoring that condition. We should fix that by
releasing all named dirty bitmaps in bdrv_close() (there should not be
any unnamed bitmaps left) and moving the assertion from bdrv_delete()
there.

eight spaces), fix the line length of the comment, and add a line break

05d0fce497 iotests: Rename filter_nbd to _filter_nbd in 083
In the patch after the next, this function is moved to common.filter.
Therefore, its name should be preceded by an underscore to signify its
global availability.

To keep the code motion patch clean, we cannot rename it in the same
patch, so we need to choose some order of renaming vs. motion. It is
better to keep a supposedly global function used by only a single test
in that test than to keep a supposedly local function in a common* file
and use it from a test, so we should rename the function before moving
it.

abb3e55b5b Revert "hw/block/fdc: Implement tray status"
This reverts the changes that commit
2e1280e8ff applied to hw/block/fdc.c;
also, an additional case of drv->media_inserted use has crept in since,
which is replaced by a call to blk_is_inserted().

That commit changed tests/fdc-test.c, too, because after it, one less
TRAY_MOVED event would be emitted when executing 'change' on an empty
drive. However, now, no TRAY_MOVED events will be emitted at all, and
the tray_open status returned by query-block will always be false,
necessitating (different) changes to tests/fdc-test.c and iotest 118,
which is why this patch is not a pure revert of said commit.

12c7ec87a7 blockdev: Fix 'change' for slot devices
'change' and related operations did not work when used on guest devices
featuring removable media but no actual tray, because
blk_dev_is_tray_open() always returned false for them and the
blockdev-{insert,remove}-medium commands required it to return true.

Fix this by making blockdev-{insert,remove}-medium work on tray-less
devices. Also, blockdev-{open,close}-tray are now explicitly no-ops when
invoked on such devices, and blk_dev_change_media_cb() is instead
called by blockdev-{insert,remove}-medium (for tray-less devices only).

5a8660741a ehci: update irq on reset
After clearing the status register we also have to update the irq line
status.  Otherwise a irq which happends to be pending at reset time
causes a interrupt storm.  And the guest can't stop as the status
register doesn't indicate any pending interrupt.

Both NetBSD and FreeBSD hang on shutdown because of that.

919e11f373 gtk: use qemu_chr_alloc() to allocate CharDriverState
The gd_vc_handler() callback is using g_malloc0() to
allocate the CharDriverState struct. As a result the
logfd field is getting initialized to 0, instead of
-1 when no logfile is requested.

The result is that when running

 $ qemu-system-i386 -nodefaults -chardev vc,id=mon0 -mon chardev=mon0

qemu duplicates all monitor output to stdout as well
as the GTK window.

Not using qemu_chr_alloc() was already a bug, but harmless
until this commit

9940c3236f ivshmem: use a single eventfd callback, get rid of CharDriver
Simplify the interrupt handling by having a single callback on irq&msi
cases. Remove usage of CharDriver, replace it with
qemu_set_fd_handler(). Use event_notifier_test_and_clear() to read the
eventfd.

Before this patch, ivshmem writes the first byte received to
s->intrstatus. But ivshmem_device_spec.txt says "The status register is
set to 1 when an interrupt occurs." Fortunately, the byte usually comes
from another ivshmem device, and those always write 1.

After this commit, follows the specification, set to 1 when an interrupt
occurs.

a907ec52cc nvme: generate OpenFirmware device path in the "bootorder" fw_cfg file
Background on QEMU boot indices
-------------------------------

Normally, the "bootindex" property is configured for bootable devices
with:

  DEVICE_instance_init()
    device_add_bootindex_property(..., "bootindex", ...)
      object_property_add(..., device_get_bootindex,
                          device_set_bootindex, ...)

and when the bootindex is set on the QEMU command line, with

  -device DEVICE,...,bootindex=N

the setter that was configured above is invoked:

  device_set_bootindex()
    /* parse boot index */
    visit_type_int32()

    /* verify unicity */
    check_boot_index()

    /* store parsed boot index */
    ...

    /* insert device path to boot order */
    add_boot_device_path()

In the last step, add_boot_device_path() ensures that an OpenFirmware
device path will show up in the "bootorder" fw_cfg file, at a position
corresponding to the device's boot index. Thus guest firmware (SeaBIOS and
OVMF) can try to boot off the device with the right priority.

NVMe boot index
---------------

In QEMU commit 33739c7129,

  nvma: ide: add bootindex to qom property

the following generic setters / getters:
- device_set_bootindex()
- device_get_bootindex()

were open-coded for NVMe, under the names
- nvme_set_bootindex()
- nvme_get_bootindex()

Plus nvme_instance_init() was added to configure the "bootindex" property
manually, designating the open-coded getter & setter, rather than calling
device_add_bootindex_property().

Crucially, nvme_set_bootindex() avoided the final add_boot_device_path()
call. This fact is spelled out in the message of commit 33739c7129, and
it was presumably the entire reason for all of the code duplication.

Now, Vladislav filed an RFE for OVMF
<https://github.com/tianocore/edk2/issues/48>; OVMF should boot off NVMe
devices. It is simple to build edk2's existent NvmExpressDxe driver into
OVMF, but the boot order matching logic in OVMF can only handle NVMe if
the "bootorder" fw_cfg file includes such devices.

Therefore this patch converts the NVMe device model to
device_set_bootindex() all the way.

Device paths
------------

device_set_bootindex() accepts an optional parameter called "suffix". When
present, it is expected to take the form of an OpenFirmware device path
node, and it gets appended as last node to the otherwise auto-generated
OFW path.

For NVMe, the auto-generated part is

  /pci@i0cf8/pci8086,5845@6[,1]
       ^     ^            ^  ^
       |     |            PCI slot and (present when nonzero)
       |     |            function of the NVMe controller, both hex
       |     "driver name" component, built from PCI vendor & device IDs
       PCI root at system bus port, PIO

to which here we append the suffix

  /namespace@1,0
             ^ ^
             | big endian (MSB at lowest address) numeric interpretation
             | of the 64-bit IEEE Extended Unique Identifier, aka EUI-64,
             | hex
             32-bit NVMe namespace identifier, aka NSID, hex

resulting in the OFW device path

  /pci@i0cf8/pci8086,5845@6[,1]/namespace@1,0

The reason for including the NSID and the EUI-64 is that an NVMe device
can in theory produce several different namespaces (distinguished by
NSID). Additionally, each of those may (optionally) have an EUI-64 value.

For now, QEMU only provides namespace 1.

Furthermore, QEMU doesn't even represent the EUI-64 as a standalone field;
it is embedded (and left unused) inside the "NvmeIdNs.res30" array, at the
last eight bytes. (Which is fine, since EUI-64 can be left zero-filled if
unsupported by the device.)

Based on the above, we set the "unit address" part of the last
("namespace") node to fixed "1,0".

OVMF will then map the above OFW device path to the following UEFI device
path fragment, for boot order processing:

  PciRoot(0x0)/Pci(0x6,0x1)/NVMe(0x1,00-00-00-00-00-00-00-00)
          ^        ^   ^    ^    ^   ^
          |        |   |    |    |   octets of the EUI-64 in address order
          |        |   |    |    NSID
          |        |   |    NVMe namespace messaging device path node
          |        PCI slot and function
          PCI root bridge
