Nikhil Benesch c0208dffbe arena: derive alignment unit from std::max_align_t 
Summary:
As raised in #2265, the arena allocator will return memory that is improperly aligned to store a `std::function` on macOS. Oddly, I'm unable to tickle this bug without adding a `std::function` field to `struct ReadOptions`—but my proposal in #2265 does exactly that.

In any case, here's a simple reproduction. Apply this bogus patch to get a `std::function` into `struct ReadOptions`

```
 --- a/include/rocksdb/options.h
+++ b/include/rocksdb/options.h
@@ -1035,6 +1035,8 @@ struct ReadOptions {
   // Default: 0
   uint64_t max_skippable_internal_keys;

+  std::function<void()> foo;
+
   ReadOptions();
   ReadOptions(bool cksum, bool cache);
 };
```

then compile `db_properties_test` *with ubsan* and run `ReadLatencyHistogramByLevel`:

```
$ make COMPILE_WITH_UBSAN=1 db_properties_test
$ ./db_properties_test --gtest_filter=DBPropertiesTest.ReadLatencyHistogramByLevel
```

ubsan will complain about several misaligned accesses:

```

```

So it seems the root cause is that the internal implementation of `std::function` on macOS (and perhaps with libc++ generally?) requires 16-byte aligned memory, but the arena allocator only guarantees that the returned memory will be `sizeof(void*)` aligned, which is only 8-byte alignment on my machine. This patch solves the problem by adjusting the allocator to derive the necessary alignment from `alignof(std::max_align_t)`, which is properly 16 bytes on my machine.

As I mentioned in #2265, none of RocksDB's tests will cause this unaligned access to actually abort the process, but, on macOS, linking CockroachDB against a version of RocksDB with the above patch and letting it run for just a few seconds will cause a SIGABRT.

```

```

I'd get you a backtrace, but [Go doesn't include cgo debug information on macOS](https://github.com/golang/go/issues/6942). I've also tried building against libc++ on Linux, where debug information would be available, but I can't seem to trigger the bug there.

In any case, this PR both fixes the segfault in CockroachDB and fixes the warnings reported by ubsan.
Closes https://github.com/facebook/rocksdb/pull/2347
