when setting config keys, validate against struct before writing to disk

When setting config keys, the program doesn't know whether the
key-to-be-modified exists on the Config struct. (Perhaps, with
reflection, it is possible to find the field). To allow callers to write
non-existent keys, the program would...

Before:
1) converts the in-memory *Config to a map
2) sets the key on the map, and
3) writes this map to disk.
4) Then, it converts this map back into an in-memory struct.

This commit swaps 3 and 4 so the map can be validated against the struct
before being written to disk. This prevents the bug identified in #740.

<jbenet> Any idea why this job isn't finding Go?
  https://travis-ci.org/jbenet/go-ipfs/jobs/49296465 --
  we havent had problems for a while and now lots of
  builds fail like this.
<•meatballhat> jbenet: still around?
<•meatballhat> jbenet: the `release` name was something specific to
  gvm. As there is no `release` tag in the go repo, it's no longer a
  valid target. What you probably want is `1.4.1` or `master`.
<jbenet> meatballhat: ah thank you
<•meatballhat> jbenet: np, sorry about the switchup!  gvm had been
  woefully undermaintained since August, so we were long overdue in
  replacing it.

logs: removed all log.Errors unhelpful to users

Let's save log.Error for things the user can take action on.
Moved all our diagnostics to log.Debug. We can ideally reduce them
even further.

AddrSplosion III - Revenge of the granular TTL

TODOs:
- need to consolidate all the versioning stuff into one package
- need to do the version check as a handshake, before further
  communication happens. we used to do this.

this will help us introspect what's going on.

it keeps failing early.

so that we dont get stuck dialing bad addrs first always.
