The previous formuation with multiple assignments to __typeof(*hptr) falls
down when hptr is qualified const. E.g. with const struct S *p, p->f is
also qualified const.
With this formulation, there's no assignment to any local variable.

The code at the beginning of qemu/bswap.h is attempting to standardize

In the case of CONFIG_BYTESWAP_H, we get bswap_N from the system header
and then wrap these with inline functions to get bswapN.

The type_register_static() interface is documented as:
type_register_static:
@info: The #TypeInfo of the new type.
@info and all of the strings it points to should exist for the life
time that the type is registered.
But cpu_register() uses a stack variable for the 'info' argument, so it
has to use type_register() instead of type_register_static().

The commit 258711 introduced MemoryRegion to replace ioport_region*
for ioport 80h and F0h.
A MemoryRegion needs to have both read and write callback otherwise a segfault
will occur when an access is made.
The previous behaviour of this both ioport is to return 0xffffffffffffffff.
So keep this behaviour.

Starting with release 1.4 we have a fully functional q35 machine type,
i.e. "qemu -M q35" JustWorks[tm]. Update machine type names to reflect
that:
* pc-1.4 becomes pc-i440fx-1.4
* q35-next becomes pc-q35-1.4
The pc-1.3 (+older) names are maintained for compatibility reasons.
For the same reason the "pc" and "q35" aliases are kept. pc-piix-1.4
continues to be the default machine type, again for compatibility
reasons.
Also updated the description (shown by "qemu -M ?") with host bridge
name, south bridge name and chipset release year.

Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

The current implementation of os_host_main_loop_wait() on Windows,
returns 1 only when a g_poll() event occurs because the return value of
select() is overridden. This is wrong as we may skip a socket event, as
shown in this example:
1. select() returns 0
2. g_poll() returns 1 (socket event occurs)
3. os_host_main_loop_wait() returns 1
4. qemu_iohandler_poll() sees no socket event because select() has
return before the event occurs
5. select() returns 1
6. g_poll() returns 0 (g_poll overrides select's return value)
7. os_host_main_loop_wait() returns 0
8. qemu_iohandler_poll() doesn't check for socket events because the
return value of os_host_main_loop_wait() is zero.
9. goto 5
This patch use one variable for each of these return values, so we don't
miss a select() event anymore.
Also move the call to select() after g_poll(), this will improve latency
as we don't have to go through two os_host_main_loop_wait() calls to
detect a socket event.

To use the online disk snapshot for online-backup, application-level
consistency of the snapshot image is required. However, currently the
guest agent can provide only filesystem-level consistency, and the
snapshot may contain dirty data, for example, incomplete transactions.
This patch provides the opportunity to quiesce applications before
snapshot is taken.
If --fsfreeze-hook option is specified, the hook is executed with
"freeze" argument before the filesystem is frozen by fsfreeze-freeze
command. As for fsfreeze-thaw command, the hook is executed with "thaw"
argument after the filesystem is thawed.
