[Qemu-devel] [PATCH V4 2/3] tests/migration: Add migration-test header file

[Wei Huang <wei@redhat.com>]

This patch moves the settings related migration-test from the
migration-test.c file to a seperate header file. It also renames the
x86-a-b-bootblock.s file extension from .s to .S, allowing gcc
pre-processor to include the C-style header file correctly.
