There are three important remarks in relation to the non-qapi command:
1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc'
commands to return an error when qemu is built without VNC support
(ie. --disable-vnc). The non-qapi command would return the OK
response in QMP and no response in HMP
2. The qapi version explicitly marks the fields 'host', 'family',
'service' and 'auth' as optional. Their are not documented as optional
in the non-qapi command doc, but they would not be returned if
vnc support is disabled. The qapi version maintains the same
semantics, but documents those fields correctly
3. The 'clients' field, which is a list, is marked as optional but is
always returned. If there are no clients connected an empty list
is returned. This is not the Right Way to this in the qapi but it's
how the non-qapi command used to work

The biggest change is to rename its prefix from BDRV_IOS to
BLOCK_DEVICE_IO_STATUS.
Next commit will convert the query-block command to the QAPI
and that's how the enumeration is going to be generated.

A future commit will convert bdrv_info() to the QAPI and it won't
provide IOS_INVAL.
Luckily all we have to do is to add a new 'iostatus_enabled'
member to BlockDriverState and use it instead.

Today we generate something like this:
int qmp_marshal_input_query_foo(...)
...
retval = qmp_query_foo(errp);
qmp_marshal_output_query_foo(retval, ret, errp);
...
However, if qmp_query_foo() fails 'retval' will probably be NULL,
which can cause a segfault as not all visitors check if 'retval'
is valid.
This commit fixes that by changing the code generator to only
call the output marshal if qmp_query_foo() succeeds, like this:
retval = qmp_query_foo(errp);
if (!error_is_set(errp)) {
qmp_marshal_output_query_foo(retval, ret, errp);
}

Use target_ulong instead of hard-coded uint32_t.
Remove the disabled printf's that are redundant with -strace.

Don't confuse the load address with the load bias. They're equal
for ET_DYN objects (i.e. ld.so) but different for ET_EXEC objects
(i.e. statically linked).

For OBS, we're running a full cross-guest inside of a VM. When a build
is done there, we reboot the guest as shutdown mechanism.
Unfortunately, reboot is not implemented in linux-user. So this mechanism
fails, spilling unpretty warnings. This patch implements sys_reboot()
emulation.

When running openat using qemu-arm, we stumbled over invalid permissions
on the created files. The reason for this is that the mode parameter gets
treates as an O_... flag, which it isn't - it's a permission bitmask.
This patch removes the needless translation of the mode parameter,
rendering permission passing of openat() to work with linux-user.

While ALIGNADDR was implemented out-of-line, ALIGNADDRL was not
implemeneted at all. However, this is a very simple operation
so we're better off doing this inline.

This reduces the size of the individual translation blocks, since
we only emit a single call for each FOP rather than three. In
addition, clear_float_exceptions expands inline to a single byte store.

This allows a more efficient representation for 64-bit hosts.
It should be about the same for 32-bit hosts, as we can still
access the individual pieces of the double.

Begin using i64 quantities to manipulate double-precision values.
On a 64-bit host this will, for the moment, generate less efficient
code; on a 32-bit host code quality should be largely unchanged.
Code quality for 64-bit will be adjusted with a subsequent patch.

Load, store, and "create destination". This version attempts to
change the behaviour of the translator as little as possible. We
previously used cpu_tmp32 as the temporary destination, and we
continue to use that. This will eventually allow a change in
representation of the fprs.
Change the name of the cpu_fpr array to make certain that all
instances are converted.
