fuse: no longer require fuse to compile ipfs

This commit removes the dependency on go-fuse-version, and thus the
fuse headers. It also introduces an elaborate troubleshooting process
that diagnoses whether fuse installed -- and which version -- with as
little requirements as possible (attept to use sysctl, fall-back on
the go-fuse-version binary, etc). It then nicely instructs the user
what to do next.

p2p/net: dial log -> events

+ fixed race

Allow sharness to run daemon without FUSE

cc @whyrusleeping: you werent doing so
cc @mappum: you were trying to escape them, but
   were un-escaping them in cases with longer quotes.

In OSX, the `echo -n` was _somehow_ printing "-n" out... not
really sure why, as the bsd `echo` program supports -n. I changed
this to printf -- which is safer.

Let's use `>file`, not `> file`, as it makes it easier to parse.

This commit allows sharness tests to run daemon tests when the FUSE
option is off. Unsure why this was previously included.

Fix daemon initialization output change

initialize if not already initialized

remove gateway fs

add gateway server

Since commit 76d9d89a, there is
"Initializing daemon..." printed on the standard output when
the daemon is started.

This means that tests have to be fixed accordingly.

fixes breakages:
  - peer.Peer -> peer.ID
  - peer.X -> peer.PeerInfo
  - netmsg -> p2p streams

This commit turns all dial logs into log.Events.

Everything's great except for one problem:
The LoggableMap I'm using does not print out things
correctly. I gave it peer.IDs, and Multiaddrs
and both got logged as nothing `{}` (didn't even call
their String() methods!) So, for now, this function
encodes it when called... This is wrong and should be
fixed before being merged in. Otherwise we  will be
constantly encoding peer.IDs and Multiaddrs without
needing to.

@briantigerchow how do you suggest doing this?
I don't know my way around your Loggable.
