This commit adds an option to turn off all encryption. This is a mode
used for tests, debugging, achieving protocol implementation interop,
learning about how the protocol works (nc ftw), and worst case
networks which _demand_ to be able to snoop on all the traffic.
(sadly, there are some private intranets like this...). (We should
consider at least _signing_ all this traffic.)
Because of the severity of this sort of thing, this is an
all-or-nothing deal. Either encryption is ON or OFF _fully_.
This way, partially unencrypted nodes cannot be accidentally left
running without the user's understanding. Nodes without encrypted
connections will simply not be able to speak to any of the global
bootstrap nodes, or anybody in the public network.

daemon output now includes initial swarm addresses. this is not a
full solution, as a change in network will not trigger re-printing.
We need a good way to do that.
This made me re-think how we're outputting these messages, perhaps
we should be throwing them as log.Events, and capturing some with
a special keyword to output to the user on stdout. Things like
network addresses being rebound, NATs being holepunched, external
network addresses being figured out, connections established, etc
may be valuable events to show the user. Of course, these should be
very few, as a noisy daemon is an annoying daemon.

Instead of just terminating right there and then, we cancel the
context, and let the daemon exit cleanly. This make take a few
seconds, as the node builder and its child processes do not
care too much about the context state while building nodes,
but this can be improved by injecting checks for ctx.Done()
before time-consuming steps.
Instead of assuming the command is the daemon command and closing
the node, which resulted in bugs like #1053, we cancel the context
and let the context children detect the cancellation and gracefully
clean up after themselves.
The shutdown logging has been moved into the daemon command, where
it makes more sense, so that commands like ping will not print out
the same output on cancellation.
We now consider debugerrors harmful: we've run into cases where
debugerror.Wrap() hid valuable error information (err == io.EOF?).
I've removed them from the main code, but left them in some tests.
Go errors are lacking, but unfortunately, this isn't the solution.
It is possible that debugerros.New or debugerrors.Errorf should
remain still (i.e. only remove debugerrors.Wrap) but we don't use
these errors often enough to keep.
this more clearly explains that the daemon is listening on the network. it also hints as to how to change the listening ports. this is also related to #874
This allows someone to host a static site by pointing a TXT record at their
content in IPFS, and a CNAME record at an IPFS gateway.
Note that such a setup technically violates RFC1912 (section 2.4; "A CNAME
record is not allowed to coexist with any other data."), but tends to work in
practice.
We may want to consider changing the DNS->IPFS resolution scheme to allow this
scenario to be RFC-compliant (e.g. store the mapping on a well-known subdomain
to allow CNAME records on the domain itself).

fix(cmd/daemon) set node on req context since it expects daemon to be
present when handling commands over the API
@jbenet revenge of the request context redux
- core: daemon stdout print to cmd + daemon init checks
- core: fixed bug where the gateway was printed as "API"
- sharness/test-lib: daemon init checks
- sharness/test-lib: portable TCP port check
- sharness/init: fix test bits output
- sharness: use common hashes in one place.
- move t0100-http-gateway -> t0111-gateway-writable
- sharness: test-lib funcs for gateway config
- sharness/t0111-gateway-writable: use sh funcs
- sharness/t0111-gateway-writable: fixes
- escape all vars (always `cmd "$VAR"` never `cmd $VAR`)
- use $FILEPATH, not $path
- last test seems to fail
