[PATCH 01/12] maint: rename md5sum.c to more general digest.c

[Pádraig Brady]

md5sum.c will be the base for all digest functions,
so rename accordingly.

* src/md5sum.c: Rename to ...
* src/digest.c: ... renamed from md5sum.c
* scripts/git-hooks/commit-msg: Allow digest: commit prefix.
* po.POTFILES.in: Adjust to new name.
* src/local.mk: Likewise.
