Extend the the release_revisions() function so that it frees the "mailmap" in the "struct rev_info". The log family of functions now calls the clear_mailmap() function added in fa8afd18e5a (revisions API: provide and use a release_revisions(), 2021-09-19), allowing us to whitelist some tests with "TEST_PASSES_SANITIZE_LEAK=true". Unfortunately having a pointer to a mailmap in "struct rev_info" instead of an embedded member that we "own" get a bit messy, as can be seen in the change to builtin/commit.c. When we free() this data we won't be able to tell apart a pointer to a "mailmap" on the heap from one on the stack. As seen inea57bc0d41(log: add --use-mailmap option, 2013-01-05) the "log" family allocates it on the heap, but in the find_author_by_nickname() code added inea16794e43(commit: search author pattern against mailmap, 2013-08-23) we allocated it on the stack instead. Ideally we'd simply change that member to a "struct string_list mailmap" and never free() the "mailmap" itself, but that would be a much larger change to the revisions API. We have code that needs to hand an existing "mailmap" to a "struct rev_info", while we could change all of that, let's not go there now. The complexity isn't in the ownership of the "mailmap" per-se, but that various things assume a "rev_info.mailmap == NULL" means "doesn't want mailmap", if we changed that to an init'd "struct string_list we'd need to carefully refactor things to change those assumptions. Let's instead always free() it, and simply declare that if you add such a "mailmap" it must be allocated on the heap. Any modern libc will correctly panic if we free() a stack variable, so this should be safe going forward.
