Another step in moving the vlan feature out of net core. Users only
deal with NetClientState and therefore qemu_del_vlan_client() should be
named qemu_del_net_client().

Now that VLANClientState has been renamed to NetClientState all 'vc'
local variables should be 'nc'. Much of the code already used 'nc' but
there are places where 'vc' needs to be renamed.

The vlan feature is no longer part of net core. Rename VLANClientState
to NetClientState because net clients are not explicitly associated with
a vlan at all, instead they have a peer net client to which they are
connected.
This patch is a mechanical search-and-replace except for a few
whitespace fixups where changing VLANClientState to NetClientState
misaligned whitespace.

There is no longer a distinction between vlan clients and non-vlan
clients in the net core. The net core only knows about point-to-point
clients which are connected to a peer. It's time to rename the global
list of net clients since it no longer refers to vlans at all.

Instead of using VLANState use net/hub.h to support the vlan qdev
property. The vlan qdev property becomes an alias for the peer qdev
property but is represented as a VLAN ID number. When a VLAN ID is
selected the device will really peer with a hub port.

Checks can be performed to make sure that hubs have at least one NIC and
one host device, warning the user if this is not the case.
Configurations which do not meet this rule tend to be broken but just
emit a warning. This patch preserves compatibility with the checks
performed by net core on vlans.

Remove an out of date comment: this comment used to be attached to
cpu_register_physical_memory_log(), before commit 0f0cb164 accidentally
inserted a couple of other functions between the comment and its function.
It is in any case obsolete since (a) the function arguments it refers
to have been replaced with a single MemoryRegionSection* argument and
(b) the inability to handle regions whose offset_within_address_space
and offset_within_region aren't equally aligned was fixed as part of
the rewrite of this code.

Registering a multi-page memory region that is non-page-aligned results
in a subpage from the start to the page boundary, some number of full
pages, and possibly another subpage from the last page boundary to the
end. The full pages will have a value for offset_within_region that is
not a multiple of TARGET_PAGE_SIZE. Accesses through softmmu are unable
to handle this and will segfault.
Handling full pages through subpages is not optimal, but only
non-page-aligned mappings take the penalty.

subpage_register() expects "end" to be the last byte in the mapping.
Registering a non-page-aligned memory region that extends up to or
beyond a page boundary causes subpage_register() to silently fail
through the (end >= PAGE_SIZE) check.
This bug does not cause noticeable problems for mappings that do not
extend to a page boundary, though they do register an extra byte.

For command line options which permit '?' meaning 'please list the
permitted values', add support for 'help' as a synonym, by abstracting
the check out into a helper function.
This change means that in some cases where we were being lazy in
our string parsing, "?junk" will now be rejected as an invalid option
rather than being (undocumentedly) treated the same way as "?".
Update the documentation to use 'help' rather than '?', since '?'
is a shell metacharacter and thus prone to fail confusingly if there
is a single character filename in the current working directory and
the '?' has not been escaped. It's therefore better to steer users
towards 'help', though '?' is retained for backwards compatibility.
We do not, however, update the output of the system emulator's -help
(or any documentation autogenerated from the qemu-options.hx which
is the source of the -help text) because libvirt parses our -help
output and will break. At a later date when QEMU provides a better
interface so libvirt can avoid having to do this, we can update the
-help text too.

glibc 2.16 will remove the undocumented definition of 'struct siginfo'
from <bits/siginfo.h>.
This change is already present in glibc 2.15.90, so qemu compilation
of certain targets (eg. cris-user) breaks.
This struct was always typedef'd to be the same as 'siginfo_t' which
is what POSIX documents, so use that instead.

MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.
This patch:
- moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
- stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
- uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

The distinction between QEMU_CFLAGS and CFLAGS is that the
former is for flags without which QEMU can't compile, whereas
the latter is for flags like "-g -O2" which the user can

Don't run configure tests with -Werror in the compiler flags. The idea
of -Werror is that it makes problems very obvious to developers, so
they get fixed quickly. However, when running configure tests, failures
due to -Werror are far from obvious -- they simply result in the test
quietly failing when it should have passed. Not using -Werror is in
line with recommended practice in the Autoconf world.
This commit is essentially backing out the changes in commit 417c9d72.
Instead we fix the problem that commit was trying to address in a
different way: we add -Werror only for the test of the nss headers,
with a comment that this is specifically intended to detect a bug
in some releases of nss.
We also have to clean up a bug in the smartcard test where it was
trying to include smartcard_cflags in the test compile flags: this
would always result in a failure with -Werror, because they include
an escaped "$(SRC_PATH)" which is only valid when used in the final
makefile.

Split the configure test that checks for valgrind into two, one
part checking whether we have the gcc pragma to disable unused-but-set
variables, and the other part checking for the existence of valgrind.h.
The first of these has to be compiled with -Werror and the second
does not and shouldn't generate any warnings.
This (a) allows us to enable "make errors in configure tests be
build failures" and (b) enables use of valgrind on systems with
a gcc which doesn't know about -Wunused-but-set-varibale, like
Debian squeeze.

Added (msi|msix)_set_message() function for whoever might
want to use them.
Currently msi_notify()/msix_notify() write to these vectors to
signal the guest about an interrupt so the correct values have to
written there by the guest or QEMU.
For example, POWER guest never initializes MSI/MSIX vectors, instead
it uses RTAS hypercalls. So in order to support MSIX for virtio-pci on
POWER we have to initialize MSI/MSIX message from QEMU.

This per-device notifier shall be triggered by any interrupt router
along the path of a device's legacy interrupt signal on routing changes.
For simplicity reasons and as this is a slow path anyway, no further
details on the routing changes are provided. Instead, the callback is
expected to use pci_device_route_intx_to_irq to check the effect of the
change.
Will be used by KVM PCI device assignment and VFIO.

Device assigned on KVM needs to know the mode
(enabled/inverted/disabled) and the IRQ number that a given device
triggers in the attached interrupt controller.
Add a PCI IRQ path discovery function that walks from a given device to
the host bridge, and gets this information. For
this purpose, a host bridge callback function is introduced:
route_intx_to_irq. It is so far only implemented by the PIIX3, other
host bridges can be added later on as required.
Will be used for KVM PCI device assignment and VFIO.
Based on patch by Jan Kiszka, with minor tweaks.

BARs are registered in init functions from memory regions created
by the drivers. Exit functions destroy those memory regions.
By unregistering the io regions after exit(), we're calling
memory_region_del_subregion on freed memory. Don't do that. The
option rom comes along for the ride because it's more symmetric
to how it's created.

Not a single driver has any possibility of failure on their
exit function, let's keep it that way.

Finally, complete the fully specified interface. msix_add_config()
gets folded into msix_init() because we now have quite a few parameters
to pass and rolling it in let's us error earlier, avoiding the ugly
unwind exit path. msix_mmio_setup() also gets rolled in, just because
it's redundant to rediscover offsets when we already have them for
such a tiny function.
