Return allocation error in deserialize instead of panicking - #238

There's no way to catch allocation errors since out of memory errors cause an abort. Fail gracefully by returning the error instead of panicking.

I happened upon this error when deserializing untrusted data with bincode. Bincode provides a byte limit bound but for sequences it's not possible to enforce this through serde since collection types like smallvec handle their own allocation.
