It is yet unclear whether this should really be considered a bug in the
test case or whether blk_unref() should work for callers that haven't
taken the AioContext lock, but in order to fix the build tests quickly,
just take the AioContext lock around blk_unref().

Currently, the default values for werror and rerror have to be set
explicitly with blk_set_on_error() by the callers of blk_new(). The only
caller actually doing this is blockdev_init(), which is called for
BlockBackends created using -drive.
In particular, anonymous BlockBackends created with
-device ...,drive=<node-name> didn't get the correct default set and
instead defaulted to the integer value 0 (= BLOCKDEV_ON_ERROR_REPORT).
This is the intended default for rerror anyway, but the default for
werror should be BLOCKDEV_ON_ERROR_ENOSPC.
Set the defaults in blk_new() instead so that they apply no matter what
way the BlockBackend was created.

The upper limit on the L2 cache size is increased from 1 MB to 32 MB
on Linux platforms, and to 8 MB on other platforms (this difference is
caused by the ability to set intervals for cache cleaning on Linux
platforms only).
This is done in order to allow default full coverage with the L2 cache
for images of up to 256 GB in size (was 8 GB). Note, that only the
needed amount to cover the full image is allocated. The value which is
changed here is just the upper limit on the L2 cache size, beyond which
it will not grow, even if the size of the image will require it to.

Sufficient L2 cache can noticeably improve the performance when using
large images with frequent I/O.
Previously, unless 'cache-size' was specified and was large enough, the
L2 cache was set to a certain size without taking the virtual image size
into account.
Now, the L2 cache assignment is aware of the virtual size of the image,
and will cover the entire image, unless the cache size needed for that is
larger than a certain maximum. This maximum is set to 1 MB by default
(enough to cover an 8 GB image with the default cluster size) but can
be increased or decreased using the 'l2-cache-size' option. This option
was previously documented as the *maximum* L2 cache size, and this patch
makes it behave as such, instead of as a constant size. Also, the
existing option 'cache-size' can limit the sum of both L2 and refcount
caches, as previously.

Adding a lookup table for the powers of two, with the appropriate size
prefixes. This is needed when a size has to be stringified, in which
case something like '(1 * KiB)' would become a literal '(1 * (1L << 10))'
string. Powers of two are used very often for sizes, so such a table
will also make it easier and more intuitive to write them.
This table is generatred using the following AWK script:
BEGIN {
suffix="KMGTPE";
for(i=10; i<64; i++) {
val=2**i;
s=substr(suffix, int(i/10), 1);
n=2**(i%10);
pad=21-int(log(n)/log(10));
printf("#define S_%d%siB %*d\n", n, s, pad, val);

The bdrv_reopen_prepare() function checks all options passed to each
BlockDriverState (in the reopen_state->options QDict) and makes all
necessary preparations to apply the option changes requested by the
user.
Options are removed from the QDict as they are processed, so at the
end of bdrv_reopen_prepare() only the options that can't be changed
are left. Then a loop goes over all remaining options and verifies
that the old and new values are identical, returning an error if
they're not.
The problem is that at the moment there are options that are removed
from the QDict although they can't be changed. The consequence of this
is any modification to any of those options is silently ignored:
(qemu) qemu-io virtio0 "reopen -o discard=on"
This happens when all options from bdrv_runtime_opts are removed
from the QDict but then only a few of them are processed. Since
it's especially important that "node-name" and "driver" are not
changed, the code puts them back into the QDict so they are checked
at the end of the function. Instead of putting only those two options
back into the QDict, this patch puts all unprocessed options using
qemu_opts_to_qdict().
update_flags_from_options() also needs to be modified to prevent
BDRV_OPT_CACHE_NO_FLUSH, BDRV_OPT_CACHE_DIRECT and BDRV_OPT_READ_ONLY
from going back to the QDict.

In the previous patches we removed all child references from
bs->{options,explicit_options} because keeping them is useless and
wrong.
Because of this, any attempt to reopen a BlockDriverState using a
child reference as one of its options would result in a failure,
because bdrv_reopen_prepare() would detect that there's a new option
(the child reference) that wasn't present in bs->options.
But passing child references on reopen can be useful. It's a way to
specify a BDS's child without having to pass recursively all of the
child's options, and if the reference points to a different BDS then
this can allow us to replace the child.
However, replacing the child is something that needs to be implemented
case by case and only when it makes sense. For now, this patch allows
passing a child reference as long as it points to the current child of
the BlockDriverState.
It's also important to remember that, as a consequence of the
previous patches, this child reference will be removed from
bs->{options,explicit_options} after the reopening has been completed.

Block drivers allow opening their children using a reference to an
existing BlockDriverState. These references remain stored in the
'options' and 'explicit_options' QDicts, but we don't need to keep
them once everything is open.
What is more important, these values can become wrong if the children
change:
$ qemu-img create -f qcow2 hd0.qcow2 10M
$ qemu-img create -f qcow2 hd1.qcow2 10M
$ qemu-img create -f qcow2 hd2.qcow2 10M
$ $QEMU -drive if=none,file=hd0.qcow2,node-name=hd0 \
-drive if=none,file=hd1.qcow2,node-name=hd1,backing=hd0 \
-drive file=hd2.qcow2,node-name=hd2,backing=hd1
After this hd2 has hd1 as its backing file. Now let's remove it using
block_stream:
(qemu) block_stream hd2 0 hd0.qcow2
Now hd0 is the backing file of hd2, but hd2's options QDicts still
contain backing=hd1.

Monochrome cursors are still used by Windows guests with the
QXL-WDDM-DOD driver. Such cursor types have one odd feature, inversion
of colors. GDK does not seem to support it, so implement an alternative
solution: fill the inverted pixels and add an outline to make the cursor
more visible. Tested with the text cursor in Notepad and Windows 10.
cursor_set_mono is also used by the vmware GPU, so add a special check
to avoid breaking its 32bpp format (tested with Kubuntu 14.04.4). I was
unable to find a guest which supports the 1bpp format with a vmware GPU.
The old implementation was buggy and removed in v2.10.0-108-g79c5a10cdd
("qxl: drop mono cursor support"), this version improves upon that by
adding bounds validation, clarifying the semantics of the two masks and
adds a workaround for inverted colors support.

[ kraxel: minor codestyle fix ]
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
When processing monitor config from guest store head0 width and height
for single-head configurations. Use these when creating the
DisplaySurface in the local renderer.
This fixes a rendering issue with wayland. Wayland rounds up the
framebuffer width and height to a multiple of 64, so with odd
resolutions (800x600 for example) the framebuffer is larger than the
actual screen. The monitor config has the actual screen size though.
This fixes guest display for anything using the local renderer
(non-spice UI, screendump monitor command).

This patch adds edid support to the qemu stdvga. It is turned off by
default and can be enabled with the new edid property. The patch also
adds xres and yres properties to specify the video mode you want the
guest use. Works only with edid enabled and updated guest driver.
The mmio bar of the stdvga has some unused address space at the start.
It was reserved just in case it'll be needed for virtio, but it turned
out to not be needed for that. So let's use that region to place the
EDID data block there.
