Now that all front end use qemu_chr_fe_init(), we can move chardev
claiming in init(), and add a function deinit() to release the chardev
and cleanup handlers.
The qemu_chr_fe_claim_no_fail() for property are gone, since the
property will raise an error instead. In other cases, where there is
already an error path, an error is raised instead. Finally, other cases
are handled by &error_abort in qemu_chr_fe_init().

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type(). But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:
| struct q_obj_ImageInfoSpecificQCow2_wrapper {
| ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
| ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
| ImageInfoSpecificKind type;
| union { /* union tag is @type */
| void *data;
|- ImageInfoSpecificQCow2 *qcow2;
|- ImageInfoSpecificVmdk *vmdk;
|+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
| } u;
| };
Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:
|@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member

Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

(Applying this to -trivial because it _is_ rather trivial
and because Jan does not reply for months)
After numerous reports that -smb (or -netdev user,smb=foo) not working
with modern windows (win7 and vista are reported as non-working), I
started digging myself. And found that indeed it doesn't work, and
why.
The thing is that modern win tries to connect to port 445 (microsoft-ds)
first, and if that fails, it falls back to old port 139 (netbios-ssn).
slirp code in qemu only redirects port 139, it does not touch port 445.
So the prob is that if samba is also running on the host, guest will try
to communicate using port 445, and that will succed, but ofcourse guest
will not talk with our samba but with samba running on the host.
If samba is not running on the host, guest will fall back to port 139,
and will reach the redirecting rule and qemu will spawn smbd correctly.
The solution is to redirect both ports (139 and 445), and the fix is
a one-liner, adding second call to slirp_add_exec() at the end of
net/slirp.c:slirp_smb() function (provided below).
But it looks like that is not a proper fix really, since in theory
we should redirect both ports to the SAME, single samba instance,
but I'm not sure this is possible with slirp. Well, even if two
smbd processes will be run on the same config dir, it should not
be a problem.
The one-liner (not exactly 1 since it touches previous line too) is like
this:

This results in being unable to login to the samba server from the guest OS.
