Summary:
- Update "eden daemon" to wait until edenfs is healthy before returning.
- Accept additional command line arguments and pass them through to edenfs.
- When starting edenfs as a background daemon, direct stdout and stderr to a
log file in the eden config directory.
- Update "eden shutdown" command to wait for edenfs to exit.
- Update "eden shutdown" command to print an error message if edenfs was not
running.

Summary:
This adds a --foreground flag to the "eden daemon" command, which causes the
daemon to run in the foreground, rather than daemonizing as a background
process. Additionally, this drops the --preserve-environment flag and instead
updates the CLI to always build a sane environment to run with.
This also updates the integration test code to use this flag, and wait for eden
to shut down during test clean up. Without this, the test case code could try
to clean up temporary directories before they were unmounted, which would fail.
This would leave many temporary directories behind after test runs.
This also re-organizes the temporary directory set up a bit, so that each test
uses a single top-level temporary directory. All other directories it creates
are put inside this one directory.

Summary:
This changes the way that Eden is built and deployed.
* To build the binary that must be run as `root` (but quickly drops privileges), run `buck build eden-daemon`.
* To build the CLI that communicates with the daemon (and does not require privileges), run `buck build eden-cli`.
* To build both, run `buck build eden`.
There is an example of how to build the various parts of Eden using
Buck and how to package them up in the `install` script introduced by this revision.
While here, I also cleaned up some of our build files and changed them to be
parameterized between internal and external use. In both cases, the user gets the
"unadorned" version of their primary build targets. This ensures that shortcuts such as:
```
buck test eden/fs/integration
```
do the right thing by default.
Finally, I also made `find_default_config_dir()` and `find_default_daemon_binary()`
lazy whereas `find_default_config_dir()` was previously eager.

Summary:
The _get_hg_dir() function had an incorrect return statement caused "eden init"
to fail with mercurial repositories, unless the path pointed to a shared
working directory.
Also update the code to store the path to the mercurial repository, rather than
the path to the .hg directory. Unlike git, mercurial requires the repository
path itself, and refuses to work if given a path to the .hg directory.

Summary:
This revision introduces two complementary changes:
* `eden daemon` no longer runs in the foreground.
* There is now an `eden shutdown` command to kill the daemon.
When `shutdown` is called, it tells the Thrift server to shutdown.
In turn, this causes `EdenServer::runThriftServer()` to exit,
which causes `EdenServer::run()` to exit.

Summary:
Previous to this change, if `~/local/.eden` did not exist when `eden daemon` was
run, then it would fail.
Now the logic to create `~/local/.eden` is encapsulated in `_ensure_dot_eden_folder_exists()`.
We do not call this for all subcommands because we want to make sure that running
`eden --help` does not have the side-effect of writing `~/local/.eden` if it does not exist.

Summary:
When running the CLI "daemon" command, we try killing the underlying eden
process group when we receive SIGTERM or SIGINT. (We really only want to kill
the main eden process, but we currently have to kill the entire process group
due to how sudo works.)
Since the privhelper process runs as root and is part of this process group, we
can get an EPERM error back. This was causing the CLI to fail with an
unhandled exception backtrace. This diff updates the code to ignore EPERM.

Summary:
Update the CLI to support running "init" with a mercurial repository.
This is just some bare bones framework code at the moment. It doesn't actually
import any data from mercurial at the moment, and mounting doesn't work.
