The new ipfs-test-lib.sh file contains generic test
functions.
We also start replacing fsh with a shell function named
test_fsh() in ipfs-test-lib.sh.
And we move our custom test_cmp in ipfs-test-lib.sh.

gc query queues

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.
