Up to now we only had an ioctl to reset vcpu data QEMU couldn't reach
for the initial reset, which was also called for the clear reset. To
be architecture compliant, we also need to clear local interrupts on a
normal reset.
Because of this and the upcoming protvirt support we need to add
ioctls for the missing clear and normal resets.

RNSBG is handled via the op_rosbg() helper function. But RNSBG has
the opcode 0xEC54, i.e. 0x54 as second byte, while op_rosbg() currently
checks for 0x55. This seems to be a typo, fix it to use 0x54 instead,
so that op_rosbg() does not abort() anymore if a program uses RNSBG.
I've checked with a simple test function that I now get the same results
with KVM and with TCG:
static void test_rnsbg(void)
{
uint64_t r1, r2;
r2 = 0xffff000000000000UL;
r1 = 0x123456789bdfaaaaUL;
asm volatile (" rnsbg %0,%1,12,61,16 " : "+r"(r1) : "r"(r2));
printf("r1 afterwards: 0x%lx\n", r1);
}

The qemu-option-trace.rst.inc file contains a rST documentation
fragment which describes trace options common to qemu-nbd and
qemu-img. We put this file into interop/, but we'd like to move the
qemu-nbd and qemu-img files into the tools/ manual. We could move
the .rst.inc file along with them, but we're eventually going to want
to use it for the main QEMU binary options documentation too, and
that will be in system/. So move qemu-option-trace.rst.inc to the
top-level docs/ directory, where all these files can include it via
.. include:: ../qemu-option-trace.rst.inc
This does have the slight downside that we now need to explicitly
tell Make which manuals use this file rather than relying on
a wildcard for all .rst.inc in the manual.

Some of the documentation for QEMU "tools" which are standalone
binaries like qemu-img is an awkward fit in our current 5-manual
split. We've put it into "interop", but they're not really
about interoperability.
Create a new top level manual "tools" which will be a better
home for this documentation. This commit creates an empty
initial manual; we will move the relevant documentation
files in a subsequent commit.
