pci-assign: Enable MSIX on device to match guest

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.

Check return values from g_poll and select

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.

((pde & 0x1fe000) << 19) is the bits 39:32 of the final physical address, and

Make all static TypeInfos const

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (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.

pc: rename machine types

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.
