eda61ddfef Deprecate to_vec in favour of to_bytes (Tobin C. Harding)
Pull request description:
Currently we have to method names for the same thing "copy this object into a vector". The library is easier to use if we are uniform and just use one.
Elect to use `to_bytes`, for context see discussion in PR #2585.

ACK eda61ddfef Nice. IMO we should start deprecating stuff for two releases rather than one, so that people have a year to update.
