Jump statements, such as return and continue let you
change the default flow of program execution,
but jump statements that direct the control flow to
the original direction are just a waste of keystrokes.

To fix migration between 2.7 and 2.8, some fields have
been renamed and managed with the help of a PHB property
(pre_2_8_migration):
5c4537b spapr: Fix 2.7<->2.8 migration of PCI host bridge
So we need to add them to the white list:
dma_liobn[0],
mem_win_addr, mem_win_size,
io_win_addr, io_win_size
become
mig_liobn,
mig_mem_win_addr, mig_mem_win_size,
mig_io_win_addr, mig_io_win_size

If a field changed from something to unused, the checker wasn't flagging
if the field size mismatched. This was noticed in:
http://thread.gmane.org/gmane.comp.emulators.qemu/419802
where the 4->1 size change along with field name change to 'unused'
wasn't being flagged. Fix this.

While comparing qemu-1.0 json output with qemu-2.1, a few fields got
marked unused. These need to be skipped over, and not flagged as
mismatches.
For handling unused fields, the exact number of bytes need to be skipped
over as the size of the unused field.
Currently, only the term "unused" is matched. When more field names
turn up, this will have to be updated based on the whitelist matching
method to match more such terms.

Commit 292b1634 changed the section name of "ICH9 LPC" to "ICH9-LPC",
and that causes the static checker to flag this:
Section "ICH9 LPC" does not exist in dest
This patch introduces a function that checks for section renames and
also a dictionary that maps those renames.

This is a small patch to a script; doesn't break qemu and helps with the
static checker, so it's a very low-risk patch for 2.1.
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.
