This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored.
* When updating a plugin or theme, the old version is moved to a temporary backup directory:
* `wp-content/upgrade/temp-backup/plugins/[plugin-slug]` for plugins
* `wp-content/upgrade/temp-backup/themes/[theme-slug]` for themes.
* If the update fails, then the temporary backup kept in the `upgrade/temp-backup` directory is restored to its original location.
* If the update succeeds, the temporary backup is deleted.
To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen:
* A check to make sure that the `temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.
To avoid confusion: The `temp-backup` directory will NOT be used to "roll back" a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty.

This ensures that when multiple plugins or themes are updated and one succeeds and another fails, the error is reported accordingly.
Previously, both updates would end up treated as a success, due to `$this->result` containing the result of the previous operation and not the current one.
Follow-up to [12097].

Because of changes to how PHP handles arrays used in `foreach()` loops in PHP >= 7.0, [48397] resulted in a failing test for PHP 5.6.
This calls `reset()` after using the `$results` array in the `foreach()` to ensure the array is treated the same and as expected.

This change adds a throttle mechanism to plugin and theme auto-update failure emails using similar logic to the email sent for a Core auto-update.
The first time a plugin or theme auto-update fails, the package and `new_version` will be tracked in the `auto_plugin_theme_update_emails` option. An email for this specific update attempt will not be resent.
However, if this update fails again and non-repeat failures or successful updates are also present, then the failure information will be included in that email (an email needs to be sent for the new events regardless).

When an attempt is made to update an active plugin automatically, there is the potential currently for two negative scenarios:
- The plugin can be deactivated if the Plugins admin screen is loaded when the plugin update is incomplete, causing a PHP error.
- The WSOD protection could be triggered, sending a false alarm email to the site administrator.
By enabling maintenance mode before an active plugin update is attempted, these scenarios can be avoided.
This change implements the same approach as the `Theme_Upgrader` class of using the `upgrader_pre_install` and `upgrader_post_install` hooks to toggle maintenance mode.

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.

"Install" is not a noun, and while it might be acceptable to use the verb as a noun, it is not correct. Using the correct
noun, "installation", increases clarity, especially for non-native English speakers.
This change fixes the usage in user-facing text and in developer documentation.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

Due to the `clear_update_cache` parameter not being respected, update caches were being cleared incorrectly which prevented multiple plugins to be updated at the same time in background updates - failing with a `fs_unavailable` error message.
