Subject: [PATCH v4 4/9] checkout.[ch]: introduce an *_INIT macro

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 31 May 2018 19:52:47 +0000

Add an *_INIT macro for the tracking_name_data similar to what exists
elsewhere in the codebase, e.g. OID_ARRAY_INIT in sha1-array.h. This
will make it more idiomatic in later changes to add more fields to the
struct & its initialization macro.
