We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

It's unfortunate that we cannot fully embrace template strings, but
we aren't limited to "legacy" formatting either; replace the last
remaining places where we still use string concatenation to reduce
the difference between regular and legacy style a bit.

In addition to the changes in this commit, gjs now
restricts the use of the Format module and initFormat.
We can't really replace those for translatable strings
until xgettext gains support for template strings, so
leave that bit out for now.
The other notable change is that gjs now requires
jsdoc comments. We can't plainly enable those options
without a massive amount of work first, but let's see
how requiring doc comments for new code goes.

We have initTranslations() for binding an extension's
gettext domain, but nothing to help with using gettext
from an extension.
Such help would be useful though, as an extension that
calls textdomain() like a normal application would
inadvertently changes the default domain for the whole
gnome-shell process.
Instead, extensions have to use domain-specific versions
of the gettext functions:
```js
const Gettext = imports.gettext.domain('my-extension');
const _ = Gettext.gettext;
```
Make this a bit easier by adding those functions directly
to the extensions object when initTranslations() is called,
then expose helper functions for calling them.

As of mozjs68 (gjs-1.64) `globalThis` is recommended over `window` and
it makes more sense in this context anyways. Migrate the few instances
of `window` we use and adjust the eslint configuration.
`window` will continue to resolve to `globalThis`, so this won't affect
extensions or other downstream users.

The Extensions app code is now independent enough from the rest of the code
base to move it to its own subprojects, like we did for the extensions-tool.
This allows for stand-alone builds of the app, which we are about to use
for distributing it as flatpak.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1133
I misremembered that imports.package.start() would set up the correct
gettext domain, but the module only provides a convenience method
for doing that.
Use it to bring back translations in the Extensions app, whoops.

They didn't just allow for the style patterns they were added to,
but allowed for some messed up indentation to slip through. Now
that we adapted the code to not use the old style, it's time to
drop the exceptions.

Unused variables or arguments can indicate bugs, but they can also
help document the code, in particular in case of signal handlers
and destructuring.
Account for this by keeping the error, but set up patterns that allow
us to opt out of if for individual variables/arguments. For arguments
we pick a '_' prefix, while for variables we go with a suffix instead,
to not accidentally exempt private module-scope variables.

While all javascript functions have a return value - either an explicit
one from a return statement, or an implicit "undefined" - mixing both in
the same function is almost certainly an oversight, and more often than
not a bug.
Enable the corresponding eslint rule to catch those errors.

Regarding coding style, gjs is moving in a direction that departs quite
significantly from the established style, in particular when indenting
multi-line array/object literals or method arguments:
Currently we are keeping those elements aligned, while the gjs rules now
expect them to use the regular 4-space indentation.
There are certainly good arguments that can be made for that move - it's
much less prone to leading to overly-long lines, and matches popluar JS
styles elsewhere. But switching coding style implies large diffs which
interfere with git-blame and friends, so in order to allow for a more
gradual change, add a separate set of "legacy" rules that match more
closely the style we would expect up to now.
It also disables the rules for quotes and template strings - the former
because we cannot match the current style to use double-quotes for
translatable strings and single-quotes otherwise, the latter because
template strings are still relatively new, so we haven't adopted them
yet.

All variables should be in camelCase, so configure the corresponding
rule to enforce this. Exempt properties for now, to accommodate the
existing practice of using C-style underscore names for construct
properties of introspected objects.

We replaced all Lang.bind() calls with arrow functions or the standardized
Function.prototype.bind(), at least for the former eslint has some options
to ensure that the old custom doesn't sneak back in.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/609
gjs doesn't include any gettext wrappers, and obviously can't know
about the shell's global object, so include those in the list of
globals for all sources in the gnome-shell context.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/609
gjs started to run eslint during its CI a while ago, so there is an
existing rules set we can use as a starting point for our own setup.
As we will adapt those rules to our code base, we don't want those
changes to make it harder to synchronize the copy with future gjs
changes, so include the rules from a separate file rather than using
the configuration directly.
