migration: Fix madvise breakage if host and guest have different page sizes
madvise(DONTNEED) will throw away the contents of the whole page at the
given address, even if the given length is less than the page size. One
can argue about whether that's the correct behaviour, but that's what it's
done for a long time in Linux at least.
That means that the madvise() in ram_load(), on a setup where
TARGET_PAGE_SIZE is smaller than the host page size, can throw away data
in guest pages adjacent to the one it's actually processing right now,
leading to guest memory corruption on an incoming migration.
This patch therefore, disables the madvise() if the host page size is
larger than TARGET_PAGE_SIZE. This means we don't get the benefits of that
madvise() in this case, but a more complete fix is more difficult to
accomplish. This at least fixes the guest memory corruption.

* qemu_opt_get(): returns NULL, which means "not set". Bug can bite
when value isn't the default value.
* qemu_opt_parse(): passes NULL to parse_option_bool(), which treats it
like "on". Wrong if the value is actually false. Bug can bite when
qemu_opts_validate() runs after qemu_opt_set_bool().
* qemu_opt_del(): passes NULL to g_free(), which is just fine.
* qemu_opt_foreach(): passes NULL to the callback, which is unlikely to
be prepared for it.
* qemu_opts_print(): prints NULL, which crashes on some systems.
* qemu_opts_to_qdict(): passes NULL to qstring_from_str(), which

dependent aspects of the QEMU GIC implementation:
* set the GIC_PMR.Priority field to all-ones, so that all

means all interrupts are masked, and QEMU only booted because
of a bug in the priority masking in our GIC implementation.
* add a barrier after GIC setup and before WFI to ensure that
GIC config is complete before we go into a possible low power
state. This isn't needed with the software GIC model but could
be required when using KVM and executing this code on the

There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.
This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)
To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.
I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

finally kill cpudef config section support
The external CPU models were removed on QEMU 1.2, and the support for
the "cpudef" config sections was documented as deprecated, but the
actual removal of the config section was pending.
Now that QEMU 1.3 was released, we can finally kill the support for
cpudef config sections, and support only the built-in CPU models from
target-i386/cpu.c.

curses: Remove OpenBSD workaround
I removed the same sort of workaround for OpenBSD within the
configure script with commit 4dcc3f5876fa638d5c35bd47be3b717ea74cc2e7
but didn't bother to grep further to come across this same chunk
of code in the curses code itself. So the following diff removes
the same workaround chunk within the curses code.

target-i386: Postpone cpuid_level update to realize time
Delay capping cpuid_level to 7 to realize time so property setters
for cpuid_7_0_ebx_features and "level" could be used in any order/time

Harmless, because we the error inevitably leads to another, fatal one

Fix it anyway.

qemu-options: Fix space at EOL
There's no need to add a space at the end of line.
Moreover, it can make problems in some projects that
store the help output into a file (and run couple of
tests based on that) and have space at EOL forbidden.

I'm guessing this is a hangover from a previous coreification of the mptimer
sub-module. This field is completely unused - removed.
