Mark Cave-Ayland 96e5c9bc77 migration: fix analyze-migration.py script 
Commit 61964 "Add configuration section" broke the analyze-migration.py script
which terminates due to the unrecognised section. Fix the script by parsing
the contents of the configuration section directly into a new
ConfigurationSection object (although nothing is done with it yet).

Alexander Graf b17425701d Add migration stream analyzation script 
This patch adds a python tool to the scripts directory that can read
a dumped migration stream if it contains the JSON description of the
device states. I constructs a human readable JSON stream out of it.

It's very simple to use:

  $ qemu-system-x86_64
    (qemu) migrate "exec:cat > mig"
  $ ./scripts/analyze_migration.py -f mig
