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.

Fixes the libfdt enabled build for hosts that have <machine/bswap.h>.
The code at the beginning of qemu/bswap.h is attempting to standardize
on bswapN. In the case of CONFIG_MACHINE_BSWAP_H, this is all we get.
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().

A MemoryRegion needs to have both read and write callback otherwise a segfault

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,

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

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.

When a guest enables MSIX on a device we evaluate the MSIX vector
table, typically find no unmasked vectors and don't switch the device
to MSIX mode. This generally works fine and the device will be
switched once the guest enables and therefore unmasks a vector.
Unfortunately some drivers enable MSIX, then use interfaces to send
commands between VF & PF or PF & firmware that act based on the host
state of the device. These therefore may break when MSIX is managed
lazily. This change re-enables the previous test used to enable MSIX
(see qemu-kvm a6b402c9), which basically guesses whether a vector
will be used based on the data field of the vector table.

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.
