3015372dd0 vmdk: Implement .bdrv_co_create callback
This makes VMDK support blockdev-create. The implementation reuses the
image creation code in vmdk_co_create_opts which now acceptes a callback
pointer to "retrieve" BlockBackend pointers from the caller. This way we
separate the logic between file/extent acquisition and initialization.

The QAPI command parameters are mostly the same as the old create_opts
except the dropped legacy @compat6 switch, which is redundant with
@hwversion.

5be28490ca vmdk: Refactor vmdk_create_extent
The extracted vmdk_init_extent takes a BlockBackend object and
initializes the format metadata. It is the common part between "qemu-img
create" and "blockdev-create".

Add a "BlockBackend *pbb" parameter to vmdk_create_extent, to return the
opened BB to the caller in the next patch.

9a378495c3 iotests: Make 234 stable
This test waits for a MIGRATION event with status=completed on the
source VM before querying the migration status on both source and
destination.  However, just because the source says migration has
completed does not mean the destination thinks the same.  Therefore, in
some cases, the destination VM may still report "active" instead of
"completed" when asked for its migration status.

Fix this by enabling migration events on both VMs and waiting until both
source and destination emit a status=completed MIGRATION event.

4720cbeea1 block: Fix hangs in synchronous APIs with iothreads
In the block layer, synchronous APIs are often implemented by creating a
coroutine that calls the asynchronous coroutine-based implementation and
then waiting for completion with BDRV_POLL_WHILE().

For this to work with iothreads (more specifically, when the synchronous
API is called in a thread that is not the home thread of the block
device, so that the coroutine will run in a different thread), we must
make sure to call aio_wait_kick() at the end of the operation. Many
places are missing this, so that BDRV_POLL_WHILE() keeps hanging even if
the condition has long become false.

Note that bdrv_dec_in_flight() involves an aio_wait_kick() call. This
corresponds to the BDRV_POLL_WHILE() in the drain functions, but it is
generally not enough for most other operations because they haven't set
the return value in the coroutine entry stub yet. To avoid race
conditions there, we need to kick after setting the return value.

The race window is small enough that the problem doesn't usually surface
in the common path. However, it does surface and causes easily
reproducible hangs if the operation can return early before even calling
bdrv_inc/dec_in_flight, which many of them do (trivial error or no-op
success paths).

The bug in bdrv_truncate(), bdrv_check() and bdrv_invalidate_cache() is
slightly different: These functions even neglected to schedule the
coroutine in the home thread of the node. This avoids the hang, but is
obviously wrong, too. Fix those to schedule the coroutine in the right
AioContext in addition to adding aio_wait_kick() calls.

cdc674c736 qcow2: Assert that refcount block offsets fit in the refcount table
Refcount table entries have a field to store the offset of the
refcount block. The rest of the bits of the entry are currently
reserved.

The offset is always taken from the entry using REFT_OFFSET_MASK to
ensure that we only use the bits that belong to that field.

While that mask is used every time we read from the refcount table, it
is never used when we write to it. Due to the other constraints of the
qcow2 format QEMU can never produce refcount block offsets that don't
fit in that field so any such offset when allocating a refcount block
would indicate a bug in QEMU.

67b24427fe mirror: Block the source BlockDriverState in mirror_start_job()
The mirror_start_job() function used for the commit-active job blocks
the source, target and all intermediate nodes for the duration of the
job.

   target <- intermediate <- source

Since 4ef85a9c23 this function creates a dummy mirror_top_bs that
goes on top of the source node, and it is this dummy node that gets
blocked instead. The source node is never blocked or added to the
job's list of nodes.

   target <- intermediate <- source <- mirror_top

At the moment I don't think it is possible to exploit this problem
because any additional job on 'source' would either be forbidden for
other reasons or it would need to involve an additional node that is
blocked, causing an error.

This can be seen in the error messages, however, because they never
refer to the source node being blocked:

  $ qemu-img create -f qcow2 hd0.qcow2 1M
  $ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
  $ qemu-io -c 'write 0 1M' hd0.qcow2
  $ $QEMU -drive if=none,file=hd1.qcow2,node-name=hd1
  { "execute": "qmp_capabilities" }
  { "execute": "block-commit", "arguments": {"device": "hd1", "speed": 256}}
  { "execute": "block-stream", "arguments": {"device": "hd1"}}
  { "error": {"class": "GenericError",
    "desc": "Node 'hd0' is busy: block device is in use by block job: commit"}}

After this patch the error message refers to 'hd1', as it should.

The expected output of iotest 141 also needs to be updated for the
same reason.

0015ca5cba ui: remove support for SDL1.2 in favour of SDL2
SDL1.2 was deprecated in the 2.12.0 release with:

  commit e52c6ba341
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Jan 15 14:25:33 2018 +0000

    ui: deprecate use of SDL 1.2 in favour of 2.0 series

    The SDL 2.0 release was made in Aug, 2013:

      https://www.libsdl.org/release/

    That will soon be 4 + 1/2 years ago, which is enough time to consider
    the 2.0 series widely supported.

    Thus we deprecate the SDL 1.2 support, which will allow us to delete it
    in the last release of 2018. By this time, SDL 2.0 will be more than 5
    years old.

99e1a93bbf configure: LM32 Milkymist Texture Mapping Unit (tmu2) also depends of X11
Commit 5f9b1e3506 remove the dependency between OpenGL and X11.
However the milkymist-tmu2 device do require X11.
When using SDL, the configure script sets need_x11=yes, so the X11
flags are populated to the makefiles.
When building without SDL, X11 is not pulled and populated, leading
to a link failure:

    LINK    lm32-softmmu/qemu-system-lm32

  collect2: error: ld returned 1 exit status
  gmake[1]: *** [Makefile:199: qemu-system-lm32] Error 1

Enforce the X11 dependency when the LM32 target is built.
This will allow us to build QEMU without SDL.

908b30164b iotests: Allow 147 to be run concurrently
To do this, we need to allow creating the NBD server on various ports
instead of a single one (which may not even work if you run just one
instance, because something entirely else might be using that port).

So we just pick a random port in [32768, 32768 + 1024) and try to create
a server there.  If that fails, we just retry until something sticks.

For the IPv6 test, we need a different range, though (just above that
one).  This is because "localhost" resolves to both 127.0.0.1 and ::1.
This means that if you bind to it, it will bind to both, if possible, or
just one if the other is already in use.  Therefore, if the IPv6 test
has already taken [::1]:some_port and we then try to take
localhost:some_port, that will work -- only the second server will be
bound to 127.0.0.1:some_port alone and not [::1]:some_port in addition.
So we have two different servers on the same port, one for IPv4 and one
for IPv6.

But when we then try to connect to the server through
localhost:some_port, we will always end up at the IPv6 one (as long as
it is up), and this may not be the one we want.

Thus, we must make sure not to create an IPv6-only NBD server on the
same port as a normal "dual-stack" NBD server -- which is done by using
distinct port ranges, as explained above.

dfadac9a37 iotests: Bind qemu-nbd to localhost in 147
By default, qemu-nbd binds to 0.0.0.0.  However, we then proceed to
connect to "localhost".  Usually, this works out fine; but if this test
is run concurrently, some other test function may have bound a different
server to ::1 (on the same port -- you can bind different serves to the
same port, as long as one is on IPv4 and the other on IPv6).

So running qemu-nbd works, it can bind to 0.0.0.0:NBD_PORT.  But
potentially a concurrent test has successfully taken [::1]:NBD_PORT.  In
this case, trying to connect to "localhost" will lead us to the IPv6
instance, where we do not want to end up.

Fix this by just binding to "localhost".  This will make qemu-nbd error
out immediately and not give us cryptic errors later.

(Also, it will allow us to just try a different port as of a future
patch.)

e1e6eccd49 iotests.py: Add qemu_nbd_pipe()
In some cases, we may want to deal with qemu-nbd errors (e.g. by
launching it in a different configuration until it no longer throws
any).  In that case, we do not want its output ending up in the test
output.

It may still be useful for handling the error, though, so add a new
function that works basically like qemu_nbd(), only that it returns the
qemu-nbd output instead of making it end up in the log.  In contrast to
qemu_img_pipe(), it does still return the exit code as well, though,
because that is even more important for error handling.

d339d766d1 qemu-io: Add generic function for reinitializing optind.
On FreeBSD 11.2:

  $ nbdkit memory size=1M --run './qemu-io -f raw -c "aio_write 0 512" $nbd'
  Parsing error: non-numeric argument, or extraneous/unrecognized suffix -- aio_write

After main option parsing, we reinitialize optind so we can parse each
command.  However reinitializing optind to 0 does not work on FreeBSD.
What happens when you do this is optind remains 0 after the option
parsing loop, and the result is we try to parse argv[optind] ==
argv[0] == "aio_write" as if it was the first parameter.

The FreeBSD manual page says:

  In order to use getopt() to evaluate multiple sets of arguments, or to
  evaluate a single set of arguments multiple times, the variable optreset
  must be set to 1 before the second and each additional set of calls to
  getopt(), and the variable optind must be reinitialized.

(From the rest of the man page it is clear that optind must be
reinitialized to 1).

The glibc man page says:

  A program that scans multiple argument vectors,  or  rescans  the  same
  vector  more than once, and wants to make use of GNU extensions such as
  '+' and '-' at  the  start  of  optstring,  or  changes  the  value  of
  POSIXLY_CORRECT  between scans, must reinitialize getopt() by resetting
  optind to 0, rather than the traditional value of 1.  (Resetting  to  0
  forces  the  invocation  of  an  internal  initialization  routine that
  rechecks POSIXLY_CORRECT and checks for GNU extensions in optstring.)

This commit introduces an OS-portability function called
qemu_reset_optind which provides a way of resetting optind that works
on FreeBSD and platforms that use optreset, while keeping it the same
as now on other platforms.

Note that the qemu codebase sets optind in many other places, but in
those other places it's setting a local variable and not using getopt.
This change is only needed in places where we are using getopt and the
associated global variable optind.

Some files claim that the code is licensed under the GPL, but then
suddenly suggest that the user should have a look at the LGPL.
That's of course non-sense, replace it with the correct GPL wording
instead.

c1ef0f2519 usb-mtp: breakup MTP write into smaller chunks
For every MTP_WRITE_BUF_SZ copied, this patch writes it to file before
getting the next block of data. The file is kept opened for the
duration of the operation but the sanity checks on the write operation
are performed only once when the write operation starts. Additionally,
we also update the file size in the object metadata once the file has
completely been written.

179fcf8a83 usb-mtp: Reallocate buffer in multiples of MTP_WRITE_BUF_SZ
This is a "pre-patch" to breaking up the write buffer for
MTP writes. Instead of allocating a mtp buffer equal to size
sent by the initiator, we start with a small size and reallocate
multiples (of that small size) as needed.

b4329d1a2a usb: implement XHCI underrun/overrun events
Implement underrun/overrun events of isochronous endpoints
according to XHCI spec (4.10.3.1)
Guest software restarts data streaming when receives these events.
The XHCI reports these events using interrupter assigned
to the slot (as these events do not have TRB), so current
commit adds the field of assigned interrupter to the
XHCISlot structure. Guest software assigns interrupter to the
slot on 'Address Device' and 'Evaluate Context' commands.
