This patch fixes several issues around closing char devices. Affected
were pty (timer was left behind, even running), udp (no close handling
at all) and tcp (missing async IO handler cleanup). The bugs either
caused segfaults or stalled the qemu process. So far, hot-unplugging USB
serial adapters suffered from this.

If the user specifies the backing file format,
then when opening the backing file, there is no need
to probe the (backing file) image to figure out its format.

This follows my previous patches implementing bdrv_create2
which keeps (for qcow2 only) the backing file format
as a qcow2-extension

Use a qcow2 extension to keep the backing file format.

By keeping the backing file format, we can:
1. Provide a way to know the backing file format without probing
   it (setting the format at creation time).
2. Enable using qcow2 format over host block devices.
   (only if the user specifically asks for it, by providing the format
   at creation time).

Also fixes a security flaw found by Daniel P. Berrange on [1]
which summarizes: "Autoprobing: just say no."

Qcow2 extensions are build of magic (id) len (in bytes) and data.
They reside right after the qcow2 header.
If a backing filename exists it follows the qcow2 extension (if exist)

Qcow2 extensions are read upon image open.
Qcow2 extensions are identified by their magic.
Unknown qcow2 extensions (unknown magic) are skipped.
A Special magic of 0 means end-of-qcow2-extensions.

In this patchset, to be used to keep backing file format.

Enhance cpu_memory_rw_debug so that it can write even to ROM regions.
This allows to modify ROM via gdb (I see no point in denying this to the

this patch adds some more defines from linux/pci_regs.h to
hw/pci.h. There is now no longer a need to define them in
eepro100.c, so they were removed there.

Some defines from linux/pci_regs.h had similar, but not
the same defines in hw/pci.h (PCI_REVISION_ID / PCI_REVISION,
PCI_SUBSYSTEM_VENDOR_ID / PCI_SUBVENDOR_ID,
PCI_SUBSYSTEM_ID / PCI_SUBDEVICE_ID).

I suggest to use the "standard" from linux/pci_regs.h and
replace the "old" Qemu ones. To facilitate the migration,
my patch does not remove the old defines but marks them
as obsolete. After a migration to the "standard" defines,
pci.h could use linux/pci_regs.h which is far more complete.

The patch is needed for an updated maintainer version of
hw/eepro100.c which I'd like to see in Qemu stable.

 * Remove declarations already declared in header file from eepro100.c
 * Add missing declarations from pci_regs.h to pci.h
 * Mark "non-standard" declarations in pci.h as obsolete

This patch increases by 50 % the size available for option roms.
The main motivator is that some roms grew bigger than the 64k we
currently allocate for them (Hey, it's 2009!)

One example is the gpxe project, that produces some roms with 69k,
70k, etc. The space proposed by this patch actually makes it as
big as 84k. Probably still a fit for some time.

But there is no free lunch. This space must come from somewhere,
and we take it from vga rom space. Currently, our vga roms are
around 35k in size. With this patch, option rom space will begin
just after vga ends, aligned to the next 2k boundary.

Technicaly, we could do the same with the uper space (the bios itself),
but since bochs bios is already 128 k in size, I don't see an
urgent need to do it.
