Modify the signrom.py script so that if the size byte in the header is
0 (ie. not set) then the script will set the size. If the size byte
is non-zero then we do the same as before, so this doesn't require
changes to any existing ROM sourcecode.

Our dependency mechanism works like this:
* on first build there is neither a .o nor a .d
* we create the .d as a side effect of creating the .o
* for rebuilds we know when we need to update the .o,
which also updates the .d
This system requires that you're never in a situation where there is
a .o file but no .d (because then we will never realise we need to
build the .d, and we will not have the dependency information about
when to rebuild the .o).
This is working fine for our object files, but we also try to use it
for $TARGET/config-devices.mak (where the dependency file is
in $TARGET-config-devices.mak.d). Unfortunately "make clean" doesn't
remove config-devices.mak, which means that it puts us in the
forbidden situation of "object file exists but not its .d file".
This in turn means that we will fail to notice when we need to rebuild:
mkdir build/depbug
(cd build/depbug && '../../configure')
make -C build/depbug -j8
make -C build/depbug clean
echo "CONFIG_CANARY = y" >> default-configs/arm-softmmu.mak
make -C build/depbug
grep CANARY build/depbug/aarch64-softmmu/config-devices.mak
The CANARY token should show up in config-devices.mak but does not.
Fix this bug by making "make clean" delete the config-devices.mak files.
config-all-devices.mak doesn't have the same problem since it has
no .d file, but delete it too, since it is created by "make" and
logically should be removed by "make clean".
(Note that it is important not to remove config-devices.mak until
after we have recursively run 'make clean' in the subdirectories.)

On Linux, sigprocmask() and pthread_sigmask() are in practice the
same thing (they only set the signal mask for the calling thread),
but the documentation states that the behaviour of sigprocmask() in a
multithreaded process is undefined. Use pthread_sigmask() instead
(which is what we do in almost all places in QEMU that alter the
signal mask already).

Commit "fd3c136 vga: make sure vga register setup for vbe stays intact
(CVE-2016-3712)." causes a regression. The win7 installer is unhappy
because it can't freely modify vga registers any more while in vbe mode.
This patch introduces a new sr_vbe register set. The vbe_update_vgaregs
will fill sr_vbe[] instead of sr[]. Normal vga register reads and
writes go to sr[]. Any sr register read access happens through a new
sr() helper function which will read from sr_vbe[] with vbe active and
from sr[] otherwise.
This way we can allow guests update sr[] registers as they want, without
allowing them disrupt vbe video modes that way.

multiple possibilities.
The information is added under
/local/domain/<backend-domid>/device-model/<domid>/backends
before the "running" state is written to Xenstore. Using a directory
for each backend enables us to add parameters for specific backends
in the future.
This interface is documented in the Xen source repository in the file

Type QJSON lets you build JSON text. Its interface mirrors (a subset
of) abstract JSON syntax.
QAPI output visitors also produce JSON text. They assert their
preconditions and invariants, and therefore abort on incorrect use.
Contrastingly, QJSON does *not* detect incorrect use. It happily
produces invalid JSON then. This is what migration wants.
QJSON was designed for migration, and migration is its only user.
Move it to migration/ for proper coverage by MAINTAINERS, and to deter
accidental use outside migration.
