Their usages are as follows: - commit_rewrite_person() takes a commit buffer and replaces the author and committer idents with their canonical versions using the mailmap mechanism - rewrite_ident_line() takes author/committer header lines from the commit buffer and replaces the idents with their canonical versions using the mailmap mechanism. This patch moves commit_rewrite_person() and rewrite_ident_line() to ident.c which contains many other functions related to idents like split_ident_line(). By moving commit_rewrite_person() to ident.c, we also intend to use it in git-cat-file to replace committer and author idents from the headers to their canonical versions using the mailmap mechanism. The function is moved as is for now to make it clear that there are no other changes, but it will be renamed in a following commit.
