When irr member of IOAPICState is not saved and loaded,
restoring becomes non-deterministic, because irr is kept from

I applied your patch to qemu 1.0 and it stopped crashing.
By the way, I also created implementation of coroutine-win32.c, which
uses WinAPI TLS functions directly (without using __thread specifiers).
It works fine too.
Pavel Dovgaluk
This patch directly uses WinAPI TLS instead of __thread specifier.
It was created because of gcc-mingw error which causes incorrect
operation of __thread variables.

This patch fixes save/restore of serial interface's state.
It includes changing of fcr setter function (it now does not invoke
an interrupt while loading vmstate), and saving/restoring all
fields that describe the state of serial interface (including timers).

I thought about splitting. First change is not for refactoring,
it is also a bugfix of non-deterministic loading of serial interface state.
Both part of my patch relate to the same problem - non-deterministic load.

Do you have an idea how to implement "needed" function for my case?
Because I think, these fields should always be saved and loaded, because
they are related to the main state of the interface, not the kind of
optional substate.

If the port is disabled, the state will not be saved, isn't it?
