log-for-trace.h: Split out parts of log.h used by trace.h
A persistent build problem we see is where a source file
accidentally omits the #include of log.h. This slips through
local developer testing because if you configure with the
default (log) trace backend trace.h will pull in log.h for you.
Compilation fails only if some other backend is selected.
To make this error cause a compile failure regardless of
the configured trace backend, split out the parts of log.h
that trace.h requires into a new log-for-trace.h header.
Since almost all manual uses of the log.h functions will
use constants or functions which aren't in log-for-trace.h,
this will let us catch missing #include "qemu/log.h" more

qapi: Add device ID and head parameters to screendump
QEMU's screendump command can only take dumps from the primary display.
When using multiple VGA cards, there is no way to get a dump from a
secondary card or other display heads yet. So let's add a 'device' and
a 'head' parameter to the HMP and QMP commands to be able to specify
alternative devices and heads with the screendump command, too.

spice: add cursor_dmabuf support
Add support for cursor dmabufs. qemu has to render the cursor for
that, so in case a cursor is present qemu allocates a new dmabuf, blits
the scanout, blends in the pointer and passes on the new dmabuf to
spice-server. Without cursor qemu continues to simply pass on the
scanout dmabuf as-is.

vnc: deal with surface NULL pointers
Secondary displays in multihead setups are allowed to have a NULL
DisplaySurface. Typically user interfaces handle this by hiding the
window which shows the display in question.
This isn't an option for vnc though because it simply hasn't a concept
of windows or outputs. So handle the situation by showing a placeholder
DisplaySurface instead. Also check in console_select whenever a surface
is preset in the first place before requesting an update.
This fixes a segfault which can be triggered by switching to an unused
display (via vtrl-alt-<nr>) in a multihead setup, for example using
-device virtio-vga,max_outputs=2.

ui/gtk: use GtkGlArea on wayland only
For dma-buf support we need a egl context. The gtk x11 backend uses glx
contexts though. We can't use the GtkGlArea widget on x11 because of
that, so use our own gtk-egl code instead. wayland continues to use
the GtkGlArea widget.

build: try improve handling of clang warnings
This patch disables the pragma diagnostic -Wunused-but-set-variable for
clang in util/coroutine-ucontext.c.
This in turn allows us to remove it from the configure check, so the
CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE will succeed for clang.
With that in place clang builds (linux) will use -Werror by default,
which breaks the build due to warning about unaligned struct members.
Just turning off this warning isn't a good idea as it indicates
portability problems. So make it a warning again, using
-Wno-error=address-of-packed-member. That way it doesn't break the
build but still shows up in the logs.
Now clang builds qemu without errors. Well, almost. There are some
left in the rdma code. Leaving that to the rdma people. All others can
use --disable-rdma to workarounds this.

In 2c9bb29703c I added a migration test that purposely fails;
unfortunately it prints a copy of the failure message to stderr
which makes the output a bit messy.
Hide stderr for that test.
