Summary:
This diff includes the following changes:
- Typically, we stat the monitored file to check for changes. Then, if changes
are detected, we open/fstat the file. If open fails, on subsequent
operations, we can skip the stat check.
- 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
call-back being called.

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`.

Summary:
While testing with the fb-eden rpm installed, I hit some integration
test failures. These were caused by the integration tests picking up the
default post-clone hook configuration.
This diff changes our existing `systemConfigDir` option (which defaults to
`/etc/eden/config.d`) to `etcEdenDir` (which defaults to `/etc/eden`) and
adjusts the code that consumed `systemConfigDir` to construct the effective
value by computing `etcEdenDir + "config.d"`.
Doing this allows us to also default the `repoHooks` path to be
`etcEdenDir + "hooks"` rather than just hard coding `/etc/eden/hooks`.
The result of this is that our integration tests will now pass when `fb-eden`
is installed, because they override the `etcEdenDir` option and isolate their
`edenfs` processes from the globally installed configuration.

This is a utility class that I'd like to use in place of the raw boost
property tree in our ClientConfig code.
It encapsulates the underlying property tree and provides a couple of simple
methods; one for loading data from a config file and one for looking up
a configuration value.
The configuration value lookup will replace tokens of the form `${KEY}`
with the value of `KEY` from its internal replacements dictionary.
This mirrors the interpolation handling that we do in the equivalent python

Summary:
This cleans up construction of the EdenMount and Dirstate objects:
- The EdenMount constructor is now responsible for creating the Overlay and
Dirstate objects.
- The Dirstate constructor is now responsible for loading the
DirstatePersistence file.
- The EdenMount now takes ownership of the ClientConfig object, and stores it
for later use.
- The ClientConfig object now has a method to get the path to the
DirstatePersistence file.
- I added a ClientConfig::createTestConfig() method, so that the TestMount code
can now use the same EdenMount constructor as the normal code.
This simplifies the logic in EdenServiceHandler and TestMount, and makes some
of the initialization dependencies a little bit simpler.
This change is necessary in order for me to move some logic from
fusell::MountPoint into EdenMount. The Dirstate object will need a pointer
back to its EdenMount object, and this diff enables that.

Summary:
This design is inspired by that of Git hooks:
https://git-scm.com/docs/githooks
By default, `/etc/eden/hooks` should be the place where Eden looks for
hooks; however, this can be overridden in `~/.edenrc` on a per-`repository` basis.
This directory should be installed as part of installing Eden.
There is information in `eden/hooks/README.md` about this.
The first hook that is supported is for post-clone logic for a repository.
This change demonstrates the need for an `eden config --get <value>`
analogous to what Git has, as hooks should be able to leverage this in their
own scripts. There introduces a `TODO` in `post-clone.py` where such a
feature would be useful, so that I could add the following to my `~/.edenrc`
to develop the Eden extension for Hg:
```
[hooks]
hg.edenextension = /data/users/mbolin/fbsource/fbcode/eden/hg/eden
[repository fbsource]
path = /data/users/mbolin/fbsource
type = hg
hooks = /data/users/mbolin/eden-hooks
```
Note that this revision also introduces a `generate-hooks-dir` script that can be
used to generate the standard `/etc/eden/hooks` directory that we intend to
distribute with Eden. This is also useful in creating the basis for a custom `hooks`
directory that can be specified as shown above in an `~/.edenrc` file.
