qemu-char: Convert udp backend to QAPI
Convert the udp char backend to the new style QAPI framework.

util/qemu-sockets.c: Support specifying IPv4 or IPv6 in socket_dgram()
Currently you can specify whether you want a UDP chardev backend
to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the
QemuOpts parsing code in inet_dgram_opts(). However the QMP struct
parsing code in socket_dgram() doesn't provide this flexibility
(which in turn prevents us from converting the UDP backend handling
to the new style QAPI framework).
Use the existing inet_addr_to_opts() function to convert the
remote->inet address to option strings; this handles ipv4 and
ipv6 flags as well as host and port. (It will also convert any
'to' specification, which is harmless as it is ignored in this
context.)

blockdev: Refuse to drive_del something added with blockdev-add
For some device models, the guest can prevent unplug. Some users need a
way to forcibly revoke device model access to the block backend then, so
the underlying images can be safely used for something else.
drive_del lets you do that. Unfortunately, it conflates revoking access
with destroying the backend.
Commit
9063f81 made drive_del immediately destroy the root BDS. Nice:
the device name becomes available for reuse immediately. Not so nice:
the device model's pointer to the root BDS dangles, and we're prone to
crash when the memory gets reused.
Commit
d22b2f4 fixed that by hiding the root BDS instead of destroying
it. Destruction only happens on unplug. "Hiding" means removing it
from bdrv_states and graph_bdrv_states; see bdrv_make_anon().
This "destroy on revoke" is a misfeature we don't want to carry
forward to blockdev-add, just like "destroy on unplug" (commit
2d246f0). So make drive_del fail on anything added with blockdev-add.
We'll add separate QMP commands to revoke device model access and to
destroy backends.

block: extend BLOCK_IO_ERROR event with nospace indicator
Management software, such as RHEV's vdsm, want to be able to allocate
disk space on demand. The basic use case is to start a VM with a small
disk and then the disk is enlarged when QEMU hits a ENOSPC condition.
To this end, the management software has to be notified when QEMU
encounters ENOSPC. The solution implemented by this commit is simple:
it extends the BLOCK_IO_ERROR with a 'nospace' key, which is true
when QEMU is stopped due to ENOSPC.
Note that support for querying this event is already present in
query-block by means of the 'io-status' key. Also, the new 'nospace'
BLOCK_IO_ERROR field shares the same semantics with 'io-status',
which basically means that werror= has to be set to either
'stop' or 'enospc' to enable 'nospace'.
Finally, this commit also updates the 'io-status' key doc in the

rules.mak: Fix DSO build by pulling in archive symbols
This fixes an issue with module build system. block/iscsi.so is
currently broken:
$ ~/build/last/qemu-img
Failed to open module: /home/fam/build/master/block-iscsi.so:
undefined symbol: qmp_query_uuid
qemu-img: Not enough arguments
Try 'qemu-img --help' for more information
To fix this, we should (at least) let qemu-img link qmp_query_uuid from
libqemustub.a. (There are a few other symbols missing, as well.)
This patch changes the linking rules to:
1) Build ".mo" with "ld -r -o $@ $^" for each ".so", and later build .so
with it.
2) Always build all the .mo before linking the executables. This is
achieved by adding those .mo files to the executables' "-y"
variables.
3) When linking an executable, those .mo files in its "-y" variables are
filtered out, and replaced by one or more -Wl,-u,$symbol flags. This
is done in the added macro "process-archive-undefs".
These "-Wl,-u,$symbol" flags will force ld to pull in the function
definition from the archives when linking.
Note that the .mo objects, that are actually meant to be linked in
the executables, are already expanded in unnest-vars, before the
linking command. So we are safe to simply filter out .mo for the
purpose of pulling undefined symbols.
process-archive-undefs works as this: For each ".mo", find all the
undefined symbols in it, filter ones that are defined in the
archives. For each of these symbols, generate a "-Wl,-u,$symbol" in
the link command, and put them before archive names in the command
line.

spapr_pci: map the MSI window in each PHB
On sPAPR, virtio devices are connected to the PCI bus and use MSI-X.
Commit
cc943c36faa192cd4b32af8fe5edb31894017d35 has modified MSI-X
so that writes are made using the bus master address space and follow
the IOMMU path.
Unfortunately, the IOMMU address space address space does not have an
MSI window: the notification is silently dropped in unassigned_mem_write
instead of reaching the guest... The most visible effect is that all
virtio devices are non-functional on sPAPR since then. :(
This patch does the following:
1) map the MSI window into the IOMMU address space for each PHB
- since each PHB instantiates its own IOMMU address space, we
can safely map the window at a fixed address (SPAPR_PCI_MSI_WINDOW)
- no real need to keep the MSI window setup in a separate function,
the spapr_pci_msi_init() code moves to spapr_phb_realize().
2) kill the global MSI window as it is not needed in the end
