Interesting migration include path. Similarly:
xbzrle.h is only exported for migration. Nothing else can use them.
So we can't put that on include/migration/*
$ git grep -F '#include "../' tests | egrep -v

Do the 4 files marked [*] belong to include/migration/?
The split is:
include/migration/* <- exported for everybody to use
migration/*.h <- Only for migration
Now, doing tests for migration makes this difference complicated,
because some tests really need things that are not exported.
This is the way that it is normally used in the tree, no?
