This one is needed for changees happening on fdc. It allows you to send
arrays of structs whose size we want to send it is another field with type
uint8_t. (If you have been able to read the whole sentence without
stoping for breathing, you can use it.

In a later patch, we introduce pre_save() and post_save() functions.
The whole point of that operation is to change things in the state.
Without this patch, we have to remove the const qualifier in each
use with a cast

PCI device entries have to have a default version, not 2, because they are
used in the midle of other structures that can have _any_ version number.
We can't use proper versioning here until we have SubSections support.
Why we didn't noticed before? Because in a PC, the only device ported with
a version less that 2 is piix_pm, and for that one, default pci values are
right. If you use a virtio-console, you will see that its state it is not
loaded back.
Thanks to Amit Shah for reporting the problem and help debug the fix.

This patch introduces VMState infrastructure, to convert the save/load
functions of devices to a table approach. This new approach has the
following advantages:
- it is type-safe
- you can't have load/save functions out of sync
- will allows us to have new interesting commands, like dump <device>, that
shows all its internal state.
- Just now, the only added type is arrays, but we can add structures.
- Uses old load_state() function for loading old state.

While reading Chris's code for fd migration I noticed the duplication
between QEMUFilePopen and QEMUFileStdio. This fixes it, and makes
qemu_fopen more similar qemu_popen.

This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and
updates later added users of qemu_register_reset), we solved the

All,
I've recently been playing around with migration via exec. Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened. This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time. This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.
(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)
