Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.
While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.
This changeset implements the following logic (only applied if WordPress is installed in the root directory):
* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.
Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.
New functions and hooks:
* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.

This change introduces a new Composer script, `compat` that will scan the codebase for (detectable) potential PHP compatibility issues using the `PHP_CodeSniffer` and a custom ruleset based off of the `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).
The command will be run as a separate job within each Travis build. While many compatibility issues and false positives have already been corrected in this commit and other Trac tickets, there are still some remaining. For that reason, the job is allowed to fail while the remainder of the potential compatibility issues are investigated and addressed. After those are resolved, the job should be set as required to pass to help prevent new compatibility issues from being introduced.

The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), JSON extension related polyfills and backwards compatibility code can now be removed.
This change removes code that supported JSON related functionality on older versions of PHP. This includes (but is not limited to) checks that `json_last_error()` exists, checking and setting the `JSON_UNESCAPED_SLASHES` and `JSON_PRETTY_PRINT` constants if not previously defined, and deprecating the `_wp_json_prepare_data()` function (which was 100% workaround code).
Follow up of [46205].

Removing the direct SQL query in `do_all_pings()` improves filterability.
As part of this change, the signature of `do_enclose()` is changed so that
a null `$content` parameter can be passed, with the `$content` then inferred
from the `$post` passed in the second parameter. In addition, the second
parameter was modified so that a post ID or a `WP_Post` object can be
provided. These changes make it possible to trigger enclosure checks with
a post ID alone (as in `do_all_pings()`) and also brings the function
signature in line with `do_trackbacks()` and `pingback()`.

This changes the "discourage search engines" option to output a `noindex, nofollow` robots meta tag. `Disallow: /` is removed from the `robots.txt` to allow search engines to discover they are requested not to index the site.
Disallowing search engines from accessing a site in the `robots.txt` file can result in search engines listing a site with a fragment (a listing without content).

* Add missing translator comments.
* Fix placement of some translator comments. Translator 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 translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

Convert `date_i18n()` into a wrapper for `wp_date()`.
