`PrintWriter#println` doesn't pay attention to the terminal
configuration that we specify so it breaks tests on Windows. If we
instead always use `PrintWriter#print('\n')` then the tests work
properly on windows *and* the CLI actually works properly on Windows.

This commit adjusts the invocation of the main response constructor as
these were changed upstream to remove a parameter.

The SQL CLI was being a bit cavalier about `null`, `ctrl-c`, and
`ctrl-d` while reading passwords to the point where it'd halt with
an exception if the user hit `ctrl-d` while typing a password. This
changes it so that the CLI will instead shut down if the user
`ctrl-c`s or `ctrl-d`s while on the password prompt with an
ENOPERM error code.
This also fixes a packaging test failure I caused by a copy and paste
error where the CLI was always enforcing things as though it was reading
a password all the time. This error was causing packaging test failures.

I'm really really sad to be removing the cli-fixture but I've had
trouble with it leaking recently it is pretty slow. Beyond that, we'd
prefer that our test fixture only fixture things that are external
depndencies.
So, yeah, I'm removing it. So we get faster tests and no chance of
leaking processes. We lose some "realness" in the tests. Instead of
interacting with the CLI like a real user we embed it in the test
process. That means we don't test the forking, we don't test the
executable jar, and we don't test the jLine console detection stuff. On
the other hand we were kind of forcing the jLine console detection stuff
in a funky way with the fixture anyway. And we test the executable jar
in the packaging tests. And that'll have to do.
I haven't renamed `RemoteCli` because it'd bloat this commit with
mechanical changes that'd make it hard to review. I'll rename it in a
followup commit.
This also updates jLine so we can disable blinking to matching
parentheses during testing. I have no clue why, but this wasn't
happening when we used the fixture. The trouble with the blinking is
that it is based on *time* so it slows things down. Worse, it works
inconsistently! Sometimes it spits out sensible ascii codes and
sometimes it, well, spits out weird garbage. When you use it in person
it works fine though. So we keep it on when not testing.
Cleans up some redundancy in when testing CLI errors. Less copy and
paste good.
I was tempted to disable the xterm emulation entirely while working on
this because upgrading jLine changed a few things and it was a real pain
to update. But If we turned that off then we'd have *nothing* testing
the colors and such. That'd be a shame because we use color in the
output to commicate stuff. I like it so I don't want to break it.
While I was there, I replaces the cli connector's `PrintWriter` with a
`BufferedWriter`. The `PrintWriter` was kind of a trap because `println`
would fail to work properly on windows because we force the terminal
into xterm mode and it doesn't know what to do with windows line
endings. Windows.....
Additionally I fixed a race condition between disabling echo when
reading passwords and fast writers. We were disabling the echo shortly
after sending the prompt. A fast enough writer could send us text before
the echo disable kicked in. Now I delegate to `LineReader#readLine`
with a special echo mask that disables echo. This is both easier to test
and doesn't seem to have the race condition. This race condition was
failing the tests because they are so much faster now. Yay!

This is the next step in removing the top level sql directory.
I named the directory `sql-cli` instead of `cli` because that puts it at
the maven coordinates `org.elasticsearch.plugin:sql-cli` instead of
`org.elasticsearch.plugin:cli`.
