Also add symlinks from the old `bin/` and `tests/` locations to avoid
breaking scripts and other tools.
Motivations:
* Scripts and tests no longer have to do dubious things like:
require('ep_etherpad-lite/node_modules/foo')
to access packages installed as dependencies in
`src/package.json`.
* Plugins can access the backend test helper library in a non-hacky
way:
require('ep_etherpad-lite/tests/backend/common')
* We can delete the top-level `package.json` without breaking our
ability to lint the files in `bin/` and `tests/`.
Deleting the top-level `package.json` has downsides: It will cause
`npm` to print warnings whenever plugins are installed, npm will
no longer be able to enforce a plugin's peer dependency on
ep_etherpad-lite, and npm will keep deleting the
`node_modules/ep_etherpad-lite` symlink that points to `../src`.
But there are significant upsides to deleting the top-level
`package.json`: It will drastically speed up plugin installation
because `npm` doesn't have to recursively walk the dependencies in
`src/package.json`. Also, deleting the top-level `package.json`
avoids npm's horrible dependency hoisting behavior (where it moves
stuff from `src/node_modules/` to the top-level `node_modules/`
directory). Dependency hoisting causes numerous mysterious
problems such as silent failures in `npm outdated` and `npm
update`. Dependency hoisting also breaks plugins that do:
require('ep_etherpad-lite/node_modules/foo')
For some reason strings are sometimes passed to `findUnmet()`, which
is obviously unexpected given the way the code is written. Rather than
figure out why strings are passed and how to safely avoid passing
strings, just return early. The net effect is the same, but returning
early avoids setting a property on a string, which is prohibited in
strict mode.
Benefits of `callHookFnSync()` and `callHookFnAsync()`:
* They are a lot more forgiving than `hookCallWrapper()` was.
* They perform useful sanity checks.
* They have extensive unit test coverage.
* They make the behavior of `callFirst()` and `aCallFirst()` match
the behavior of `callAll()` and `aCallAll()`.
Define states and use them to properly handle multiple calls to
`start()`, `stop()`, and `exit()`. (Multiple calls to `exit()` can
happen if there is an uncaught exception or signal during shutdown.)
This should also make it easier to add support for cleanly restarting
the server after a shutdown (for tests or via an `/admin` page).
* lint: skin-variants
* for squash: Fix attachment of event listener
Before this PR the statement was outside the function. I'm assuming
the move into the function body was accidental, so move it back out.
* for squash: Preserve order of function calls
