Recent Fedora complains while compiling ui/sdl.c:

    /usr/x86_64-w64-mingw32/sys-root/mingw/include/winsock2.h:15:2: warning: #warning Please include winsock2.h before windows.h [-Wcpp]

And with this patch we dutifully obey.

Stefan Weil:

Without that patch, windows.h will include winsock.h
(which conflicts with winsock2.h) when compiling sdl.c.

Normally we define WIN32_LEAN_AND_MEAN, and
windows.h won't include winsock.h.

include/ui/sdl2.h and ui/sdl.c undefine that macro,
so the order of the include files is important.

Return a valid value from the BCM2835 property mailbox query "get board
revision". This query is used by U-Boot. Implementing it fixes the first
obvious difference between qemu and real HW.

The value returned is currently hard-coded to match the RPi2 I own. Other
values are legal, e.g. different board manufacturer field values are
likely to exist in the wild.

mach-virt doesn't yet support hotplug, but command lines specifying
-smp <num>,maxcpus=<bigger-num> don't fail. Of course specifying
bigger-num as something bigger than the machine supports, e.g. > 8
on a gicv2 machine, should fail though. This fix also makes mach-
virt's max-cpus check truly consistent with the one in vl.c:main,
as the one there was already correctly checking max-cpus instead
of smp-cpus.

ARM stops before access to a location covered by watchpoint. Also, QEMU
watchpoint fire is not necessarily an architectural watchpoint match.
Unfortunately, that is hardly possible to ignore a fired watchpoint in
debug exception handler. So move watchpoint check from debug exception
handler to the dedicated watchpoint checking callback.

When QEMU watchpoint matches, that is not definitely an architectural
watchpoint match yet. If it is a stop-before-access watchpoint then that
is hardly possible to ignore it after throwing a TCG exception.

match before raising a TCG exception.
