[Qemu-devel] [PATCH v2] Acceptance tests: add Linux initrd checking test |

QEMU used to exits with a not accurate error message when
an initrd > 2GiB was passed. That was fixed on patch:
commit f3839fda5771596152b75dd1e1a6d050e6e6e380
Author: Li Zhijian <address@hidden>
Date: Thu Sep 13 18:07:13 2018 +0800
change get_image_size return type to int64_t
This change adds a regression test for that fix. It starts
QEMU with a 2GiB dummy initrd, and check it evaluates the file
size correctly and prints accurate message.

Changes in v2:
* disambiguous GB vs GiB in comments and commit msg [ehabkost]
* uses max_size variable [crosa]
* checks return code equals to 1 [ehabkost]
* checks expected message contain needed max_size [crosa]
