Subject: [PATCH 07/23] midx: expand test data

From: Derrick Stolee <[email-masked]>
Date: Thu, 7 Jun 2018 10:03:22 -0400

As we build the multi-pack-index file format, we want to test the format
on real repoasitories. Add tests to t5319-midx.sh that create repository
data including multiple packfiles with both version 1 and version 2
formats.

The current 'git midx write' command will always write the same file
with no "real" data. This will be expanded in future commits, along with
the test expectations.
