They are both infallible wrappers of posix_memalign and valloc. There is also moz_xmemalign, which wraps memalign, which is mostly always available as of bug 1402647. None of them are actually used, but it's still desirable to at least have one infallible variant, so keep moz_xmemalign and remove the other two. While here, we actually make both memalign and moz_xmemalign always available. --HG-- extra : rebase_source : 1c3ca4b3e3310543145f3181dfa4e764be1d6ff8
