Comment:

 > Ideally stop using bit packing entirely in memory-only structures, and
 serialize to integer types of exact size when crafting packets

 I think that the "store these as unsigned rather than as enum" approach is
 far more reasonable.  (We never serialize a struct, I hope, and the reason
 we bit-pack these things is to save RAM.  In some cases, as for circuits
 or policies, we allocate a really huge number of these things.)


 This could go either 0.2.3 or 0.2.4, but I'm leaning 0.2.4 since it's a
 nontrivial fix and MSVC is a semi-supported build environment for 0.2.3.
