tci: Fix wrong macro name for debug code

Code which is compiled with CONFIG_TCG_DEBUG (set by configure option
--enable-debug-tcg) should not disable the assert macro by
defining NDEBUG.

With the wrong macro name CONFIG_TCG_DEBUG, all assertions in tci.c

qcow2: Limit COW to where it's needed

This fixes a regression introduced in commit 250196f1. The bug leads to
data corruption, found during an Autotest run with a Fedora 8 guest.

Consider a write request whose first part is covered by an already
allocated cluster, but additional clusters need to be newly allocated.
When counting the number of clusters to allocate, the qcow2 code would
decide to do COW for all remaining clusters of the write request, even
if some of them are already allocated.

If during this COW operation another write request is issued that touches
the same cluster, it will still refer to the old cluster. When the COW
completes, the first request will update the L2 table and the second
write request will be lost. Note that the requests need not overlap, it's
enough for them to touch the same cluster.

This patch ensures that only clusters that really require COW are
considered for allocation. In this case any other request writing to the
same cluster will be an allocating write and gets serialised.

scsi: fix refcounting for reads

Recently introduced FUA support also gave us a use-after-free
of the BlockAcctCookie within a SCSIDiskReq, due to unbalanced
reference counting.

The patch fixes this by making scsi_do_read look like a combination
of scsi_*_complete + scsi_*_data.  It does both a ref (like
scsi_read_data) and an unref (like scsi_flush_complete).

slirp: don't use "smb ports = 0" option

The "smb ports = 0" option causes recent samba versions to crash. It was
introduced in commit 157777ef3e with log message "Samba 3 support".
However, a value of 0 has never been officially supported by smb and is
also not necessary: if stdin is a socket, smb does not try to listen on
any ports and uses just stdin. This is necessary to support inetd based
operation (otherwise smbd would always fail when called from inetd,
because inetd already listens on the SMB port). Since samba has
supported inetd operation since pre-3.x, it should be safe to rely on
this feature. I have tested it with Samba 3.6.4 -- communication works
fine, and smbd is not listening on any ports.

I suspect the "smb ports = 0" hack may have been introduced when someone
tested the qemu generated samba config from the command line with "smbd
-i" and found it to fail (because then stdin isn't a socket).

pseries: Use the same interrupt swizzling for host bridges as p2p bridges

Currently the pseries PCI code uses a somewhat strange scheme of PCI irq
allocation - one per slot up to a maximum that's greater than the usual 4.
This scheme more or less worked, because we were able to tell the guest the
irq mapping in the device tree, however it's a bit odd and may break
assumptions in the future.  Worse, the array used to construct the dev
tree interrupt map was mis-sized, we got away with it only because it
happened that our SPAPR_PCI_NUM_LSI value was greater than 7.

This patch changes the pseries PCI code to use the same interrupt swizzling
scheme as is standardized for PCI to PCI bridges.  This makes for better
consistency, deals better with any devices which use multiple interrupt
pins and will make life easier in the future when we add passthrough of
what may be either a host bridge or a PCI to PCI bridge.  This won't break
existing guests, because they don't assume a particular mapping scheme for
host bridges, but just follow what we tell them in the device tree (also

pseries: Implement automatic PAPR VIO address allocation

PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary,
"address" used as a token to the hypercalls which manipulate them.

Currently the pseries machine code does an ok job of allocating these
addresses when the legacy -net nic / -serial and so forth options are used
but will fail to allocate them properly when using -device.

Specifically, you can use -device if all addresses are explicitly assigned.
Without explicit assignment, only one VIO device of each type (network,
console, SCSI) will be assigned properly, any further ones will attempt
to take the same address leading to a fatal error.

This patch fixes the situation by adding a proper address allocator to the
VIO "bus" code.  This is used both by -device and the legacy options and
default devices.  Addresses can still be explicitly assigned with -device
options if desired.

This patch changes the (guest visible) numbering of VIO devices, but since
their addresses are discovered using the device tree and already differ
from the numbering found on existing PowerVM systems, this does not break
compatibility.
