Merge filter_features_for_kvm() and kvm_check_features_against_host().
Both functions made exactly the same calculations, the only difference
was that filter_features_for_kvm() changed the bits on cpu->features[],
and kvm_check_features_against_host() did error reporting.

KVM never supported the MONITOR flag so it doesn't make sense to have it
enabled by default when KVM is enabled.
The rationale here is similar to the cases where it makes sense to have
a feature enabled by default on all CPU models when on KVM mode (e.g.
x2apic). In this case we are having a feature disabled by default for
the same reasons.
In this case we don't need machine-type compat code because it is
currently impossible to run a KVM VM with the MONITOR flag set.

Grub fails to boot from internal TFTP server when loading more than
3 initrd files.
Grub first opens a session to the TFTP server for every initrd file and
retrieves only the file size for all.
Then it wants to download the content using the old sessions which are
already expired.
Increasing the maximum number of session of the internal TFTP
server avoids this issue.

This script compares the vmstate dumps in JSON format as output by QEMU
with the -dump-vmstate option.
It flags various errors, like version mismatch, sections going away,
size mismatches, etc.
This script is tolerant of a few changes that do not change the on-wire
format, like embedding a few fields within substructs.
The script takes -s/--src and -d/--dest parameters, to which filenames
are given as arguments.
Example:
(in a qemu 2.0 tree):
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json
(in a qemu 2.2 tree:)
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \
qemu-2.2-m2.0.json
./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json
The script also takes a --reverse parameter to switch the src and dest
jsons. This is just a shorthand for reversing the src and dest.
The --help parameter shows usage information.

This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.
A Python script that compares the output of such JSON dumps is included
in the following commit.
