sharness/t0110-gateway: fix /s fail on osx

Refactor/keyspace

fix locking in the pinner

the test cases were failing for me on osx. Removing /s fixes them.
It should be fine not to check the /s.

add /dev/crypto-notes.md

Fixes issue #924

test/bin: fix continueyn on Linux

It looks like there were two problems:

- "read" command probably needs the name of the variable
  it reads into

- [[ didn't work

This might be because on Linux /bin/sh is sometimes not
bash. For example on Ubuntu it is a symlink to dash.

There is no way this was safe before.

Be careful to unlock on the error paths.

No code attempts to open the same repo multiple times.

Error handling is still buggy, but it's starting to get clearer.

repo.Once now does refcounts on a whole Repo level, returning the same
pointer to multiple Openers. This removes the need for the weird model
of separate FSRepo instances pointing to the same underlying storage,
and the races caused by that.

This will replace the elaborate refcounting in fsrepo, to make it
easier to maintain.

Nobody calls At without immediately calling Open.

First step, a mechanical transformation. Cleanups will follow.

This is only called from `ipfs` command line tool well before it opens
the repo. The behavior change here causes a false positive if the
current process has already opened the repo. That's a bit late to ask
this question, anyway, and is not expected to have ever triggered.

The only caller is `ipfs init`, which at that time does not hold a
repository open, and refuses to run on existing repos anyway.

Dead code cleanup
