[Qemu-devel] [PATCH 1/2] error-report: provide error_report_exit()

[Peter Xu <peterx@redhat.com>]

There are many places in current QEMU codes that needs to print some
error and then quit QEMU. Provide a macro for it.

Also, one coccinelle script is added to convert existing cases to
leverage this new macro.
