* Add missing translators comments.
* Fix placement of some translators comments.
Translators comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools.
The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translators comments.
Includes minor code layout fixes.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.
Fixes#44600.

In order to get the best result when running `phpcbf` across the codebase, there are some manual tweaks we need to make.
These fall into three categories:
- Fixing incorrectly indented code which has flow-on effects when auto-fixing.
- Tweaking the layout of inline PHP inside HTML tags.
- Moving more complex inline PHP inside HTML tags, to execute earlier.

New functions `wp_insert_site( $data )`, `wp_update_site( $id, $data )` and `wp_delete_site( $id )` are introduced to manage site rows in the `wp_blogs` table, forming the new CRUD API together with the existing `get_site()` / `get_sites()`. The new API provides various benefits over the previously existing API, fixing several cache invalidation issues and being hook-driven so that normalization and validation of the passed data can be fully customized.
New hooks introduced as part of this are the actions `wp_insert_site`, `wp_update_site`, `wp_delete_site`, `wp_validate_site_data` and the filter `wp_normalize_site_data`.
At this point, `wp_insert_site()` does not handle setting up the site's database tables, and `wp_delete_site()` does not handle dropping the site's database tables, so the two can not yet be used directly as full replacements of `wpmu_create_blog()` and `wpmu_delete_blog()`. Managing the site's database tables will be added via hooks as part of the follow-up ticket #41333.
The existing functions `wpmu_create_blog()`, `update_blog_details()`, and `wpmu_delete_blog()` make use of the respective new counterpart and will be obsolete once #41333 has been completed.

In many a strange and curious file of forgotten lore—
While I pondered, blaming Nacin, my notifications suddenly awakened,
As of someone quietly DMing;—DMing me, I can’t ignore.
“’Tis some contributor,” I muttered, “DMing me an idea or four—
Only this and nothing more.”
Ah, distinctly I remember, at WordCamp US, last December;
A mad proposal nearly laid me—down out cold—upon the floor.
Curious, I listened closely;—to a plan I agreed with, mostly—
A way to make our JavaScript—JavaScript which was a chore—
Maintainable, extendable, for the future, is what I saw.
Guten-ready for evermore.
Open here I switch to Slack, when, with many a patch and hack,
In there stepped Omar, a JavaScript developer hardcore;
Pronouncing all the changes fit; ready now to be commit;
“There’s nothing else for us to do,” DMing me, “It’s done!” he swore—
“No longer random guessing at which file need next be explored—
Let’s move on, we’re all aboard.”
Moved all together, grouped and managed, in folders all is packaged,
The code had all been cleaned and tidied, important parts moved to the fore,
“Though this change be useful here,” I said, “it is too large, I fear,
We couldn’t manage such a patch, we’ve done nothing like this before—
Tell me where doth go this change, change to make our codebase soar!”
Quoth Omar, “In WordPress Core.”

Previously, personal data exports were stored in `wp-content/uploads/exports`, which is generic enough that it's likely there are existing folders with that name, either created by plugins or manually by administrators. If that folder were reused by Core, then `wp_privacy_delete_old_export_files()` would delete all of the existing files inside it, which is almost certainly not what the site owner wants or expects.
To avoid that, the folder is being renamed to include a specific reference to Core, and a more verbose description of its purpose. With those factored in, it's very unlikely that there will be any conflicts with existing folders.
The `wp_privacy_exports_dir()` and `wp_privacy_exports_url()` functions were introduced to provide a canonical source for the location, and the `wp_privacy_exports_dir` and `wp_privacy_exports_url` filters were introduced to allow plugins to customize it.

Previously, the link used absolute positioning, in order to stick it at the bottom of the page. That was done in order to create visual separation between it and the "action" links, like "Lost Your Password?"
The absolute positioning can cause conflicts in some situations, though. For example, if extra text or error notices are added above the form, then the login link would be positioned on top of other elements.
Switching to relative positioning with extra margins avoids those issues, while maintaining the visual separation between the "action" links and the privacy policy link.

r43158 introduced a new admin pointer for the privacy tools added in 4.9.6. With the previous positioning, though, sometimes the `Dismiss` link would be fixed off screen, making it impossible for the user to dismiss the pointer. This happened when there were enough extra menu items, or when the viewport height was short enough.
This commit repositions the pointer to work around that problem. One down side of this workaround is that the arrow will not always be positioned next to the `Tools` menu, where it should be. That's an acceptable compromise given the current time constraints, though. A long term solution would be to make `WP_Pointer` robust enough to handle this use case.

Previously, when a plugin updated its suggested privacy policy text, an admin notice was shown on all screens in the Administration Panels. That was done in order to make sure that administrators were aware of it, so that they could update their policy if needed. That was a very heavy-handed and intrusive approach, though, which leads to a poor user experience, and notice fatigue.
An alternative approach is to use bubble notifications in the menu, similar to when plugins have updates that need to be installed. That still makes it obvious that something needs the administrator's attention, but is not as distracting as a notice.
The notice will still appear on the Privacy page, though, since it is relevant to that screen, and provides an explanation of why the bubble is appearing.

Previously the pointer overlapped the menu in order to draw attention to the fact that it applies to both the `Tools` and `Settings` menus. That caused a conflict if the menu was collapsed, though, because the icons were covered by the pointer and therefore inaccessible.
Additionally, minor tweaks were made to the text order and formatting. The order of the two sections was swapped in the title and paragraph, in order to match the order of the corresponding menu items. The spacing around headings and paragraphs was tweaked to remove extraneous whitespace.

The personal data export and erasure tools allow plugins to register their own callbacks, in order to add additional data to the export and erasure processes. Previously, these were registered without specifying a constant identifier in the array of callbacks. Using mutable integers makes it difficult for plugins to modify the callbacks of other plugins, though.
Using associative array keys instead provides a covenient and reliable way to identify and interact with another plugin's callbacks.

In many common Multisite use cases, the network administrator will want to set a network-wide privacy policy -- via the `privacy_policy_url` filter -- for consistency and convenience. When that's done, the Privacy Settings screen on individual sites becomes unnecessary, and may confuse administrators of those sites when they see that their changes don't have any effect on the policy link in the footer.
Since we can't programatically determine which behavior the network admins would like, the safest default setting is to restrict the ability to super admins, and let them delegate it to individual site owners via a plugin, if they'd like to.

The page was originally placed under `Tools` so that it would be grouped with the pages to export and erase personal data, since they're all part of the effort to bring privacy management tools to Core ahead of GDPR's deadline. After more consideration, though, it makes sense to move this page to the `Settings` menu, since it's fundamental purpose is to configure an option, rather than to facilitate a recurring task. This keeps all of the configuration pages in a single place, making them consistent and easier to find.
Exporting and erasing personal data are recurring tasks, so they still make sense under the `Tools` menu.

Multisite networks have a variety of use cases, and in many of them single-site administrators are not trusted to take actions that affect the whole network, require making decisions about legal compliance, etc. By default, those actions should require super admin capabilities.

This runs immediately after the data export file has been successfully created, allowing plugins to introduce some workflow customizations. For example, a plugin could password-protect the export file, for peace of mind, even though the CSPRN in the filename makes brute force attacks nearly impossible.

git-svn-id: https://develop.svn.wordpress.org/trunk@43047 602fd350-edb4-49c9-b593-d223f7449a82
The primary means of protecting the files is the CSPRN appended to the filename, but there is no reason to keep the files after the data subject has downloaded them, so deleting them provides an additional layer of protection. Previously this was done from `wp_privacy_generate_personal_data_export_file()`, but that does not guarantee that it will be run regularly, and on smaller sites that could result in export files being exposed for much longer than necessary.
`wp_privacy_delete_old_export_files()` was moved to a front end file, so that it can be called from `cron.php`.
This introduces the `wp_privacy_export_expiration` filter, which allows plugins to customize how long the exports are kept before being deleted.
`index.html` was added to the `$exclusions` parameter of `list_files()` to make sure that it isn't deleted. If it were, then poorly-configured servers would allow the directory to be traversed, exposing all of the exported files.

The implementation fails gracefully when the new table is not yet available, which may happen especially shortly after the core update, before the network has been upgraded to the new database schema. The presence of the table is detected once and stored as a global setting on the main network.
Core does not yet use site metadata, but there are several use-cases to be implemented or explored in the near future, and it allows plugins to extend sites with arbitrary data, which will come in particularly handy with the upcoming REST API endpoint for sites.

For a number of years, the "Available Widgets" section has been off-limits for
keyboard users. Now it can be used also with the keyboard. This change introduces
also some improvements for assistive technologies.
- makes the widget toggles focusable and adds an `aria-expanded` attribute to indicate their state
- improves the toggles labelling to clarify context (add/edit)
- changes the controls to choose a sidebar from list items to buttons
- adds an `aria-label` attribute to the buttons to clarify their purpose
- adds an `aria-pressed` attribute to the buttons to indicate which one is selected
- improves color contrast of the selected button
- uses a `wp.a11y.speak()` message to announce to screen reader users when a widget has been added to a sidebar
- moves focus back to the toggle button when closing a widget
See #40677.
