Subject: [PATCH v4 01/34] builtin rebase: use FREE_AND_NULL

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Tue, 16 Apr 2019 16:33:08 +0700

From: SZEDER Gábor <[email-masked]>

Use the macro FREE_AND_NULL to release memory allocated for
'head_name' and clear its pointer.

Patch generated with 'contrib/coccinelle/free.cocci' and Coccinelle
v1.0.7 (previous Coccinelle versions don't notice this).
