- Make `ipfs files rm --force /nonexistant` succeed when the path does not exist.
- Add shaness test for removing nonexistant paths
- Refactor duplicated code to find a parent dir into a function

I've been writing scripts against the files api, and having to stat things before removing them is a pain. So this PR aims to make --force do what I'd expect it to.

Just make sure we've removed all the blocks. We can't guarantee that the size
will revert.

Write the PID file after listening.

Otherwise, we could abort while fetching the graph and stay in a state where the
direct pin is removed.

We no longer spit out the annoying http error.

All the work was client-side. Unix domain socket multiaddrs already worked
server-side.

fixes #4218

We were pining Y then removing the pin for X. When X == Y, we'd remove the new
pin.

fixes #6648

The patches that required the replace directives have been merged upstream.
Unfortunately, those branches have now been deleted, breaking the build.

GAH!

1. This means those deps don't get pulled in unless we actually need to test.
2. It means we can cordon all the golangci-lint module replace hacks off into a
   separate package.

For now, configs specified in `daemon --init-config` and `init CONFIG` are not
available. We should fix this eventually but isn't necessary for now (and
supporting this will be annoying).

"identity" is the official name

We can no longer test this with bad keys. Unfortunately, good keys will likely
contain a newline and we have no way to send such keys to the server due to how
API requests are formatted.

IPFS doesn't build correctly under non-GNU make implementations.

1. Fix handling of PUT. The simple implementation was the correct
   implementation, I have no idea what was going on here.
2. Use MFS everywhere to reduce code duplication and add support for sharded
   directories.
3. _Correctly_ block IPNS.
4. Remove the dependency on `core.IpfsNode`.
5. Remove support for putting empty directories with a well-known CID. It was
   useless as directories are automatically created.

Allow passing --long or ?long=true as a more descriptive option name than "l".

This command is no longer necessary and is quite dangerous:

1. All lockfiles are now released by the OS when the daemon stops.
2. The API file is ignored when (a) the repo is initialized and (b) daemon is
off.

This helps with issues like #4190 by telling the user the path that failed to
parse.

The git plugin is built-in. Anyways, there's no reason plugin loading shouldn't
work in travis.
