folly::readFile() doesn't work correctly on Windows. It was returning the incorrect size. I didn't check if the read contents were correct, because I was testing it on a binary data file.

The systemctl command requires XDG_RUNTIME_DIR to be configured. If it's not configured, 'eden start' should pick a sane default. The sane default includes the user's UID (e.g. /run/user/6986). I want this default to be configurable via Eden's config files.
Expose the ${USER_ID} token to Eden configs. This will let administrators can customize XDG_RUNTIME_DIR's fallback value in the future.

Summary:
Previously the default ignore path was `~/ignore`. This doesn't really seem
like a great path choice, and I suspect that no one is actually using an
ignore file at this location. This default was set in D8594297, but I it
looks like this was mostly accidental from just not separating out data for
the system ignore path (`/etc/eden/ignore`) vs the user ignore path.
Using `~/.edenignore` seems reasonable for now, and unlikely to conflict with
other paths. We used to use `~/.gitignore` as the default before D8906226,
but this did cause problems for a handful of users that treated their entire
home directory as a git repository, and had a `~/.gitignore` file that was
supposed to apply only to their home directory.

Summary:
Unfortunately, our current config parsing implementation is
forcing us to stringly-type all data, which partially defeats one
of the benefits of using a modern typed configuration file format
such as TOML.
This means that boolean options have to be specified as strings in
the config file.
I don't want to ship the Mononoke feature integration out and tell
folks to use `"true"` to turn it on as it will impose a future migration
concern on us.
This diff does the simple but gross thing: at parse time, rather than
ignoring boolean values, we convert them to string so that the upper
layer can convert them to bools again.

- We only update the stat struct of the FileChangeMonitor member when the file
is successfully opened/processed. This means that all file change checks are
done relative to the processed file (rather than the results of the previous
stat).
- We still skip open/fstat if the isChanged() check indicates a file change
because of a different stat error code. This will still result in the

Summary:
The headline changes of this revision are:
- Changes the format of the config file from INI to TOML
(the `edenrc` file under `~/local/.eden` has been replaced
with `config.toml`). This revision includes logic for automatically
performing the migration when Eden is restarted.
- Inlines data from `/etc/eden/config.d` into the TOML file.
Historically, the `edenrc` file for a client would contain the
name of the "configuration alias" defined in a config file like
`~/.edenrc` or `/etc/eden/config.d/00-defaults`. When Eden
loaded a client, it would have to first read the `edenrc` and
then reconstitute the rest of the client configuration by
looking up the alias in the set of config files that were used to
create the client in the first place.
This changes things so that all of the data that was being
cross-referenced is now inlined in the client's config file.
This makes loading a config considerably simpler at the cost
of no longer being able to change the config for multiple clients
that were cloned from the same configuration alias in one place.
It was questionable whether being able to modify a client from
a foreign config after it was created was a safe thing to do, anyway.
Eliminating the need for a historic link to the configuration alias
will make it easier to support running `eden clone` on an arbitrary
local Hg or Git repo. So long as `eden clone` can extract enough
information from the local repo to create an appropriate config file
for the new Eden client, there is no need for a configuration alias
to exist a priori.
Since we were already changing the data in the config file, this
seemed like an appropriate time to make the switch from INI to
TOML, as this was something we wanted to do, anyway.
In testing, I discovered a discrepancy between how boost's
`boost::property_tree::ptree` and Python's `ConfigParser` handled
the following section heading:
```
[repository ZtmpZsillyZeden-clone.LIkh32]
```
Apparently `hasSection("repository ZtmpZsillyZeden-clone.LIkh32")`
in boost would fail to find this section. Because
[[https://stackoverflow.com/questions/13109506/are-hyphens-allowed-in-section-definitions-in-ini-files | there is no spec for INI]],
it is not that surprising that boost and `ConfigParser` do not 100% agree
on what they accept. Moving to TOML means we have a configuration
language with the following desirable properties:
- It has a formal spec, unlike INI. This is important because there are parsers
in a wide range of programming languages that, in theory, accept a consistent
input language.
- It is reasonable for humans to write, as it supports comments, unlike JSON.
- It supports nested structures, like maps and arrays, without going crazy
on the input language it supports, unlike YAML.
Eden now depends on the following third-party TOML parsers:
* C++ https://github.com/skystrife/cpptoml
* Python https://github.com/uiri/toml
This revision also changes the organization of `~/local/.eden` slightly. For now,
there is still a `config.json` file, but the values are no longer hashes of the realpath
of the mount. Instead, we take the basename of the realpath and use that as the
name of the directory under `~/local/.eden/clients`. If there is a naming collision, we
add the first available integral suffix. Using the basename makes it easier to
navigate the `~/local/.eden/clients` directory.
Although the `edenrc` file under `~/local/.eden/clients` has been switched from INI
to TOML, the other Eden config files (`~/.edenrc` and `/etc/eden/config.d/*`) still use
INI. Migrating those to TOML will be done in a future revision.
Note this revision allowed us to eliminate `facebook::eden::InterpolatedPropertyTree`
as well as a number of uses of boost due to the elimination of
`ClientConfig::loadConfigData()` in the C++ code. Because `ClientConfig`
no longer does interpolation, a bit of `ClientConfigTest` was deleted as part of
this revision because it is no longer relevant.

Summary:
Moving the post-clone step out of C++ makes it so that
`ClientConfig` in C++ no longer knows about `hooks` and requires
`RepoConfig` to know about `hooks`. This helps us reduce
`ClientConfig`'s dependency on `ConfigData`, as my next step
is to move the remaining information that `ClientConfig` gets from
`ConfigData` directly into the client's `edenrc` file under
`~/local/.eden`.
