Update sha1dc from the latest version by the upstream maintainer[1]. This version includes a commit of mine which allows for replacing the local modifications done to the upstream files in git.git with macro definitions to monkeypatch it in place. It also brings in a change[2] upstream made for the breakage 2.13.0 introduced on SPARC and other platforms that forbid unaligned access[3]. This means that the code customizations done since the initial import in commit28dc98e343("sha1dc: add collision-detecting sha1 implementation", 2017-03-16) can be done purely via Makefile definitions and by including the content of our own sha1dc_git.[ch] in sha1dc/sha1.c via a macro. 1.cc465543b32.33a694a9ee3. "Git 2.13.0 segfaults on Solaris SPARC due to DC_SHA1=YesPlease being on by default" (https://public-inbox.org/git/CACBZZX6nmKK8af0-UpjCKWV4R+hV-uk2xWXVA5U+_UQ3VXU03g@mail.gmail.com/) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
